GuardPLC 16-Digital Inputs and 8-Digital Outputs Module 5

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as "open type" equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for additional installation requirements pertaining to this equipment.

Preventing Electrostatic Discharge

ATTENTION

This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate static

safe packaging.

Mount the Module

IMPORTANT

The module cannot be panel-mounted. Mount the module to a DIN rail by following the four steps below.

1. Hook the top slot over the DIN rail.

2. Insert a flathead screwdriver into the

gap between the housing and the latch and pull the latch downward.

3. Hold the latch down as you push the housing back onto the DIN rail.

4. Release the latch to lock the device onto the rail.

TIP

For effective cooling:

• Mount the module horizontally.

• Provide a gap of at least 100 mm (3.94 in.) above and below

the module.

• Select a location where air flows freely or use an additional fan.

• Do not mount the module over a heating device.

(2)

Latch

To remove the module from the DIN rail, insert a flathead screwdriver into the gap between the housing and the latch and pull the latch downward as you lift the module off of the rail.

(1) Top Slot

DIN Rail

IP Address Label

A transparent label shipped with the module can be used to note the IP address and system ID (SRS).

IMPORTANT

Publication 1753-IN011A-EN-P - October 2005

If you attach the label to the module, make sure you do not cover any of the ventilation slots.

GuardPLC 16-Digital Inputs and 8-Digital Outputs Module 7

Wire the Module

The following sections describe how to wire the module.

Ground the Module

You must also provide an acceptable grounding path for each device in your application. For more information on proper grounding guidelines, refer to the Industrial Automation Wiring and Grounding Guidelines, publication number 1770-4.1.

The module is functionally grounded through its DIN rail connection. A protective earth ground connection is required and is provided through a separate grounding screw, located on the upper left of the housing and marked with the grounding

symbol .

ATTENTION

This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (e.g. aluminum, plastic, etc.) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.

Connections for Safety-Related Communications

Ethernet Switch

The module has two 10/100BaseT, RJ-45 connectors to provide communications via GuardPLC Ethernet to GuardPLC controllers, and with the programming software. The connectors are located on the bottom side on the left. The connectors and the module are connected together by an internal Ethernet switch. The switches are auto-detect. Either cross-over or straight-through shielded Ethernet cabling can be used.

Star or line configurations are available. Make sure that a network loop is not generated. Data packets must only be able to reach a node via a single path.

MAC Address

The Media Access Control (MAC) Address of the module can be found on the label positioned over both lower RJ-45 connections.

8 GuardPLC 16-Digital Inputs and 8-Digital Outputs Module

Connect the Voltage Supply

The 24V dc voltage supply must feature galvanic isolation (in accordance with EN 60950 or UL 1950) since inputs and outputs are not electrically isolated from the processor. In order to comply with CE Low Voltage Directives (LVD), you must use either a NEC Class 2, a Safety Extra Low Voltage (SELV) or a Protected Extra Low Voltage (PELV) power supply to power this adapter. An SELV supply can’t exceed 30V rms, 42.4V peak or 60V dc under normal conditions and under single fault conditions. A PELV supply has the same rating and is connected to protected earth.

IMPORTANT

The supply voltage is connected via a 4-pin connector. See page 22 for the appropriate wire size. You only need to connect one wire to L+ and one wire to L-. Both L+ and L- terminals are internally connected, so you can daisy-chain 24V dc

power from the module to other devices in the panel using the remaining terminal.

ATTENTION

Protect the module with a 12 A slow-blow fuse.

Do not reverse the L+ and L- terminals or damage to the module will result. There is no reverse polarity protection.
