GENERALDESCRIPTION

The Model GMDIO14 module is a digital I/O module designed for use
with the Graphite products. This module offers eight inputs and six
outputs that can be used to monitor contact or sensor inputs and actuate
relays, solenoids, PLC inputs, etc.

The inputs accept standard DC inputs or contact closures, and are
configured for Sink/Source signals via external switches. Additionally,
each input has a switch selectable input filter that can be used to prevent
contact bounce. Each input may also be software configured as a high­active or low-active input.

The module is available with relay or NFET outputs that are capable of
switching up to one amp each (NFET DC only). For applications
requiring large loads to be controlled, several DIN rail mount relays are
available.

The modules connect and communicate via proprietary USB
connection to the various Graphite host devices. The Graphite host
devices, equipped with serial ports as well as an Ethernet port(s), allows
the system to share data with PCs, PLCs, and SCADA systems. The
maximum number of modules varies for each Graphite host device, see
specific models for details.

DIMENSIONSIninches(mm)

ForModelNo.GMDIOS00Only

Once programmed, the module will continue to operate/control
independent of the Graphite host device as long as power is applied.
Remove power from the host device before installing or replacing any
modules.

CONFIGURATION

The Graphite is configured with Windows® compatible Crimson
software. The software is an easy to use, graphical interface which
provides a means of configuration and commissioning of new systems,
as well as routine module re-calibration.

SAFETYSUMMARY

All safety related regulations, local codes and instructions that appear
in this literature or on equipment must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment
connected to it. If equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.

Do not use this unit to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially
harmful to persons or equipment in the event of a fault to the unit.

EMCINSTALLATIONGUIDELINES

Although Red Lion Controls products are designed with a high degree
of immunity to Electromagnetic Interference (EMI), proper installation and
wiring methods must be followed to ensure compatibility in each
application. The type of the electrical noise, source or coupling method
into a unit may be different for various installations. Cable length, routing,
and shield termination are very important and can mean the difference
between a successful or troublesome installation. Listed are some EMI
guidelines for a successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly

connected to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield

connection should be made as short as possible. The connection point

for the shield depends somewhat upon the application. Listed below

are the recommended methods of connecting the shield, in order of

their effectiveness.

a. Connect the shield to earth ground (protective earth) at one end

where the unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually

when the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with

AC power lines, conductors, feeding motors, solenoids, SCR controls,

and heaters, etc. The cables should be run through metal conduit that

is properly grounded. This is especially useful in applications where

cable runs are long and portable two-way radios are used in close

proximity or if the installation is near a commercial radio transmitter.

Also, Signal or Control cables within an enclosure should be routed as

far away as possible from contactors, control relays, transformers, and

other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI

suppression devices such as Ferrite Suppression Cores for signal and

control cables is effective. The following EMI suppression devices (or
equivalent) are recommended:

Fair-Rite part number 0443167251 (Red Lion Controls #FCOR0000)
Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls #LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize
radiated and conducted noise (EMI), some type of contact protection
network is normally installed across the load, the contacts or both. The
most effective location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal

oxide varistor (MOV) across an AC inductive load is very effective at
reducing EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a

transistor switch, care must be taken not to exceed the breakdown
voltage of the transistor when the load is switched. One of the most
effective ways is to place a diode across the inductive load. Most
Red Lion products with solid state outputs have internal zener diode
protection. However external diode protection at the load is always a
good design practice to limit EMI. Although the use of a snubber or
varistor could be used.
Red Lion part numbers: Snubber: SNUB0000

7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided,
they should not be mixed. Therefore a sensor common should NOT be
connected to an output common. This would cause EMI on the
sensitive input common, which could affect the instrument’s operation.

INPUTSWITCHES

Each input is independently configurable for sinking or sourcing

signals. A filter capacitor is also selectable for avoiding contact bounce.

SNK/SRC:

ON-SRC - Connects an internal 10K pull-down resistor to common.
OFF-SNK - Connects an internal 20K pull-up resistor to +5V.

FILTER:

ON - Connects a capacitor to the input, thereby reducing the input

response to 50 Hz.

OFF - Provides maximum input response of 300 Hz.
