Terminator I/O System Components

PROFIBUS

Terminator I/O is a modular system which combines the functions of terminal blocks and I/O
modules for distributed I/O. Each Terminator I/O system has the following components: a
Power Supply, a Base Controller, and one or more I/O Module(s). Terminator I/O systems
can contain up to 16 I/O modules per slave (node). Each slave (node) system can be divided
into one row of base I/O plus two rows of local expansion I/O using a base expansion cable.

Power Supplies

120/240 VAC and 12/24 VDC power supplies are available. The AC version has a built-in
24VDC supply. A power supply must be the leftmost component in a slave system followed
by the base controller. Additional power supplies should be added between I/O modules to
meet power budget requirements.

I/O Modules

A Terminator I/O module assembly consists of an I/O module and a separate base,
as shown below. A complete range of discrete modules which support 12/24 VDC,
110/220 VAC and up to 7A relay outputs is offered. The analog I/O modules provide 12-bit
and 14-bit resolution and several selections of I/O signal ranges (including bipolar). The
temperature input modules provide 16 bit resolution with several temperature input range
selections. All Terminator I/O modules can be Hot Swapped (replaced) without removing
system power (except for the base controller and power supply). Refer to the I/O Module Hot
Swap section in Chapter 3 for details.

Safety Guidelines

NOTE: Products with CE marks perform their required functions safely and adhere to relevant standards
as specified by CE directives provided they are used according to their intended purpose and that the
instructions in this manual are adhered to. The protection provided by the equipment may be impaired if this
equipment is used in a manner not specified in this manual. A listing of our international affiliates is available
on our Web site: http://www.automationdirect.com

WARNING: Providing a safe operating environment for personnel and equipment is your responsibility
and should be your primary goal during system planning and installation. Automation systems can fail
and may result in situations that can cause serious injury to personnel or damage to equipment. Do not
rely on the automation system alone to provide a safe operating environment. You should use external
electromechanical devices, such as relays or limit switches, that are independent of the PLC application
to provide protection for any part of the system that may cause personal injury or damage. Every
automation application is different, so there may be special requirements for your particular application.
Make sure you follow all national, state, and local government requirements for the proper installation
and use of your equipment.

Plan for Safety

The best way to provide a safe operating environment is to make personnel and equipment
safety part of the planning process. You should examine every aspect of the system to determine
which areas are critical to operator or machine safety. If you are not familiar with PLC system
installation practices, or your company does not have established installation guidelines, you
should obtain additional information from the following sources.

• NEMA — The National Electrical Manufacturers Association, located in Washington, D.C.
publishes many different documents that discuss standards for industrial control systems. You can
order these publications directly from NEMA. Some of these include:

ICS 1, General Standards for Industrial Control and Systems

ICS 3, Industrial Systems

ICS 6, Enclosures for Industrial Control Systems

• NEC — The National Electrical Code provides regulations concerning the installation and use of
various types of electrical equipment. Copies of the NEC Handbook can often be obtained from
your local electrical equipment distributor or your local library.

• Local and State Agencies — many local governments and state governments have additional
requirements above and beyond those described in the NEC Handbook. Check with your local
Electrical Inspector or Fire Marshall office for information.

Terminator Installation and I/O Manual, 3rd Edition, Rev. C

Three Levels of Protection

The publications mentioned provide many ideas and requirements for system safety. At a
minimum, you should follow these regulations. Also, you should use the following techniques,
which provide three levels of system control.

• Emergency stop switch for disconnecting system power

• Mechanical disconnect for output module power

• Orderly system shutdown sequence in the PLC control program

Emergency Stops

It is recommended that emergency stop circuits be incorporated into the system for every
machine controlled by a PLC. For maximum safety in a PLC system, these circuits must not
be wired into the controller, but should be hardwired external to the PLC. The emergency
stop switches should be easily accessed by the operator and are generally wired into a master
control relay (MCR) or a safety control relay (SCR) that will remove power from the PLC I/O
system in an emergency.

MCRs and SCRs provide a convenient means for removing power from the I/O system
during an emergency situation. By de-energizing an MCR (or SCR) coil, power to the input
(optional) and output devices is removed. This event occurs when any emergency stop switch
opens. However, the PLC continues to receive power and operate even though all its inputs
and outputs are disabled.

The MCR circuit could be extended by placing a PLC fault relay (closed during normal
PLC operation) in series with any other emergency stop conditions. This would cause
the MCR circuit to drop the PLC I/O power in case of a PLC failure (memory error, I/O
communications error, etc.).

Emergency Power Disconnect

A properly rated emergency power disconnect should be used to power the PLC controlled
system as a means of removing the power from the entire control system. It may be necessary
to install a capacitor across the disconnect to protect against a condition known as “outrush”.
This condition occurs when the output Triacs are turned off by powering off the disconnect,
thus causing the energy stored in the inductive loads to seek the shortest distance to ground,
which is often through the Triacs.

After an emergency shutdown or any other type of power interruption, there may be
requirements that must be met before the PLC control program can be restarted. For example,
there may be specific register values that must be established (or maintained from the state prior
to the shutdown) before operations can resume. In this case, you may want to use retentive
memory locations, or include constants in the control program to ensure a known starting
point.

Orderly System Shutdown

Ideally, the first level of fault detection is the PLC control
program, which can identify machine problems. Certain
shutdown sequences should be performed. The types o f
problems are usually things such as jammed parts, etc. that d o
not pose a risk of personal injury or equipment damage.

WARNING: The control program must not be the only form of
protection for any problems that may result in a risk of personal
injury or equipment damage.

Panel Mounting and Layout

It is important to design your panel properly to help ensure that the Terminator I/O products
operate within their environmental and electrical limits. The system installation should
comply with all appropriate electrical codes and standards. It is important that the system also
conforms to the operating standards for the application to ensure proper performance.

1. Only mount the unit horizontally as shown to provide proper ventilation.

2. If you place more than one unit in a cabinet, there should be a minimum of 7.2 in. (183mm)
between them.

3. Provide a minimum clearance of 2in. (50mm) between the units and all sides of the cabinet.
There should also be at least 1.2 in. (30mm) of clearance between the base and any wiring ducts.

Chapter 2: Installation and Wiring

4. There must be a minimum of 2in. (50mm) clearance between the panel door and the nearest
Terminator I/O component.

5. The ground terminal on the Terminator I/O power supply must be connected to a single point
ground. Use copper stranded wire to achieve a low impedance. Copper eye lugs should be
crimped and soldered to the ends of the stranded wire to ensure good surface contact. Remove
anodized finishes and use copper lugs and star washers at termination points. A general rule is
to achieve a 0.1 ohm of DC resistance between the Terminator I/O slave and the single point
ground.

6. There must be a single point ground (i.e. copper bus bar) for all devices in the panel requiring
an earth ground return. The single point of ground must be connected to the panel ground
termination. The panel ground termination must be connected to earth ground. For this
connection you should use 12AWG stranded copper wire as a minimum. Minimum wire sizes,
color coding, and general safety practices should comply with appropriate electrical codes and
standards for your region. A good common ground reference (earth ground) is essential for
proper operation of the Terminator I/O. There are several methods of providing an adequate
common ground reference, including: a) Installing a ground rod as close to the panel as possible.
b) Connection to incoming power system ground.

7. Properly evaluate any installation where the ambient temperature may approach the lower or
upper limits of the specifications. Place a temperature probe in the panel, close the door and
operate the system until the ambient temperature has stabilized. If the ambient temperature
is not within the operating specification for the Terminator I/O system, measure points in the
panel in consideration for installing a cooling/heating source to provide the ambient temperature
to meet the Terminator I/O operating specifications.

8. Device mounting bolts and ground braid termination bolts should be #10 copper bolts or
equivalent. Tapped holes instead of nut-bolt arrangements should be used whenever possible.
To ensure good contact on termination areas impediments such as, paint, other coating or
corrosion should be removed in the area of contact.

9. The system is designed to be powered by 110/220 VAC or 24VDC normally available
throughout an industrial environment. Isolation transformers and noise suppression devices
are not normally necessary, but may be helpful in eliminating/reducing suspect power problems.

Enclosures

Your selection of a proper enclosure is important to ensure safe and proper operation of
your Terminator I/O system. Applications of Terminator I/O systems vary and may require
additional features. The minimum considerations for enclosures include:

• Conformance to electrical standards

• Protection from the elements in an industrial environment

• Common ground reference

• Maintenance of specified ambient temperature

• Access to equipment

• Security or restricted access

• Sufficient space for proper installation and maintenance of equipment

Multiple Power Supplies / Local Expansion Configurations

Multiple Power Supply Configuration

It is possible to have multiple power supplies in a single slave (node) system to meet power
budget requirements. One power supply is required in the leftmost component position
followed by the base controller. Additional power supplies should be added between I/O
modules as necessary to meet power budget requirements. There are some restrictions on where
power supplies can be placed in the system when using the T1K-05CBL-RR(-1) expansion base
cable. Each power supply powers the modules to its right, but is interrupted by the next power
supply. Each slave (node) system can be divided into one row of base I/O plus two rows of
local expansion I/O up to a total of 16 I/O modules.

Expansion cables are available in two configurations: one that allows 24VDC base power to
pass and one that does not (both cables pass the 5VDC base power). The “-1” version of the
expansion cables, pass 24VDC on an isolated wire. Any local expansion DC input modules
configured for “internal power” (current sourcing) must either have a power supply preceding
it on the same base or have a “-1” version cable pass 24VDC from a power supply on the
preceding base.
