GE IC693MDL231 Input Module 8 Points 240V AC

IC693MDL231 GE Fanuc Isolated Input Module Series 90-30

Product Introduction

The IC693MDL231 is an isolated input module manufactured by GE Fanuc for the Series 90-30 programmable logic controller platform. This module provides 8 isolated input points, each with a single power input terminal, and operates on a nominal voltage of 240 Volts AC at 50/60 Hz. Each point draws 15 mA at rated voltage, ensuring compatibility with a wide range of field devices. Furthermore, the module offers 1500 V RMS isolation between the field side and the logic side, providing robust protection against voltage transients and electrical noise. The IC693MDL231 is designed to work seamlessly with Series 90-30 PLCs, supporting input devices such as electronic proximity switches, limit switches, and pushbuttons. Eight LED indicators display the ON/OFF status for each input point, while a front door panel with an insert allows clear circuit identification and wiring documentation.

Technical Specifications

The IC693MDL231 delivers reliable AC input sensing across diverse industrial applications. Below are the key technical parameters:

• Nominal Voltage: 240 V AC

• Frequency: 50/60 Hz

• Number of Inputs: 8 isolated points

• Input Current at Rated Voltage: 15 mA

• Isolation (Field to Logic): 1500 V RMS

• AC Power: Yes

• DC Power: No

• LED Indicators: 8 (one per input point)

• Baseplate Compatibility: 5-slot or 10-slot Series 90-30 baseplates

• Front Panel: Door with insert for circuit identification and wiring information

Additionally, the module's high isolation rating ensures safe operation in electrically noisy environments. This feature protects the PLC logic from field-side disturbances, thereby enhancing overall system reliability.

Input Device Compatibility

The IC693MDL231 supports a variety of AC-powered input devices commonly found in industrial automation. Specifically, it works well with:

• Electronic proximity switches

• Limit switches

• Pushbuttons

• Other dry-contact or AC-powered sensing devices

These devices require an external power source, which is supplied through the module's input terminals. Because the IC693MDL231 is an AC-only module, it does not accept DC power, so users must ensure that their field devices and power supplies match the AC specification.

Moreover, each of the 8 input points is fully isolated from the others and from the logic side, enabling the module to handle inputs from different sources without ground loop issues. Consequently, system integrators can connect diverse field devices with confidence.

LED Indicators and Front Panel Design

The IC693MDL231 features a row of 8 LEDs located on the top of the module. These indicators display the real-time ON or OFF status for input points 1 through 8, respectively. This visual feedback greatly simplifies troubleshooting and system monitoring, as technicians can quickly verify input states without accessing the PLC logic.

In addition, the module includes a front door panel with an insert that fits between the interior and exterior surfaces. The outer surface of this insert records circuit identification information, visible when the door is closed. Meanwhile, the interior surface displays detailed circuit wiring information, accessible by opening the door. The insert has a red edge, which serves as a visual warning that the IC693MDL231 is a high-voltage device (240V AC). Therefore, operators should exercise caution during installation and maintenance.

Installation Guidelines

Installing the IC693MDL231 is straightforward when following these steps:

1. Power Down – Disconnect power from the PLC rack before installation or removal.

2. Baseplate Slot Selection – Choose any available I/O slot in the 5-slot or 10-slot Series 90-30 baseplate.

3. Insertion – Slide the module along the card guides until it seats firmly into the backplane connector.

4. Wiring – Connect AC power and field device wiring to the input terminals, ensuring correct polarity and voltage levels.

5. Front Panel Setup – Insert circuit identification information on the insert as needed.

6. Power Up – Restore power and monitor the LED indicators for proper input status.

Remember that the IC693MDL231 is an AC-only module, so do not apply DC power to the inputs. Additionally, always verify that the external power source matches the 240V AC specification and that all wiring complies with local electrical codes.
