Product Description

The GE Fanuc IC693MDL655 is a 24-volt DC Positive/Negative Logic Input module. This module has been designed to work with the Series 90-30 Programmable Logic Controller. It has 32 discrete input points, divided into four groups of eight. Each group is isolated and has a shared common between the eight points. All input points on the module operate at a maximum level of 30V. They are able to operate with either positive or negative logic. There are opto-couplers on this module, which provide backplane isolation between the field side and logic side. This is in addition to the isolation from each group of inputs. On the top of the module there is an LED block, which has a corresponding ON/OFF status indicator for each of the 32 points on the module. When using field devices with the IC693MDL655, the user can hook up a power supply or else use the isolated +24 VDC supply, which is available at the I/O connectors on the module.

Users may install the input module in the baseplate of a Series 90-30 PLC system – it will work in any I/O slot. On the front of the module, there are two male 24-pin connectors. These enable user input devices to be connected to the input circuits. The right-hand side connector provides an interface for groups A and B, while the left-hand side connector is for groups C and D. To wire from the connectors to a field device, it is necessary to get a cable with tinned wires on one end and a mating female connector on the other end. Part numbers IC693CBL327 and IC693CBL328 are pre-wired cables that users may implement in their application.

The IC693MDL655 PLC is a 24 Volts DC positive/negative logic PLC manufactured by GE Fanuc. It is designed with 32 inputs. This Series 90-30 module is an industrial module. This programmable logic controller comes with 4 isolated groups of 8 with each group having its own common. The positive and negative logic inputs can operate at up to 30 Volts. An isolation of 1500 Volts exists between field side and logic side with 250 Volts of between groups. The input current rating of the IC693MDL655 PLC is 7 milliamps. The on-state voltage of the module ranges between 11.5 and 30 Volts DC and the off state ranges between 0 and 5 Volts DC. The internal power consumption rating of the controller is 195 milliamps with 5 Volts bus voltage on the backplane and 224 milliamps with 24 Volts bus voltage on the backplane. 


The front side of the IC693MDL655 PLC module has both RS 232 and RS 485 ports along with LED indicators to show different status updates. The controller is CE certified and listed with the cULus standards. The operating temperature should be set between 0 and 60 degrees Celsius for regular operation. The IC693MDL655 PLC uses 32 bits of input data. The current into an input point results in a logic 1 with the input status table. The module can be easily installed on a 5-slot or 10-slot baseplate in the PLC system. For wiring and connections, the IC693MDL655 PLC uses pre-wired cables with proper connectors.The module is manufactured with an open enclosure and it is meant to be used inside the system cabinet only.
