GENERAL DESCRIPTION

The Model GMDIO14 module is a digital I/O module designed for use with the Graphite Series. 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 high-active 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 module connects and communicates 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 device, see specific models for details.

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 Series is configured with Windows® compatible Crimson® software. The software is an easy to use, graphical interface that provides a means of communication configuration, as well as commissioning and calibration of new systems.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the manual 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 the module 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 module.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

CAUTION: Risk of electric shock.

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 (screened) cables for all Signal and Control inputs. The shield

(screen) pigtail 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.

c. Connect the shield to common of the module and leave the other end of the

shield unconnected and insulated from earth ground.

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.

Therefore, keep cable runs as short as possible.

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 (RLC part number FCOR0000) TDK part number ZCAT3035-1330A Steward part number 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (Red Lion Controls # LFIL0000) Schaffner # FN670-1.8/07 Corcom # 1 VR3

Note: Reference manufacturer’s instructions when installing a line filter.

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 RLC 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.

RLC part numbers: Snubber SNUB0000

Varistor ILS11500 or ILS23000

Note: Reference manufacturer’s instructions when installing any EMI

suppression device.

7. Also 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 effect the instrument’s operation.

guidelines, Safety and CE issues as they relate to Red Lion Controls products.

INPUT SWITCHES

Each input is independently configurable for sinking or sourcing signals. A filter

capacitor is also selectable for avoiding contact bounce.

SNK SRC

SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER SNK/SRC FILTER

FILTER ON

SNK/SRC: ON-SRC - Connects an internal 10KΩ pull-down resistor to common. OFF-SNK - Connects an internal 20KΩ 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.
