The General Electric IC693MDL230 is an 8-point, 120 VAC isolated input module designed for the Series 90-30 Programmable Logic Controller (PLC) platform. This module features reactive input circuitry, providing robust signal detection for industrial field devices such as limit switches, pushbuttons, and proximity sensors. Each of the eight input points is electrically isolated, ensuring reliable operation in environments where signal separation is required.

Features

• 8 isolated input points for 120 VAC operation
• Compatible with Series 90-30 PLC baseplates (5-slot and 10-slot)
• Reactive (resistor/capacitor) input circuitry
• Integrated LED status indicators for each point (A1-A8)
• High-voltage module identification via red color-coded edge
• User-supplied field power required for input devices

Technical Specifications

Applications

• Packaging and material handling conveyor coordination
• Water and wastewater pump status and level monitoring
• Industrial manufacturing processes including injection molding
• Building infrastructure and HVAC control systems

Installation Guidelines

• Always power down the PLC baseplate before inserting or removing the module to prevent electrical shock or hardware damage.
• The module can be installed in any available I/O slot of a Series 90-30 5-slot or 10-slot baseplate.
• Align the module carefully with the top and bottom rails, slide it into the rack, and ensure the backplane connector is fully seated.
• Secure the module by tightening the captive screw located at the bottom of the faceplate.
• Ensure field wiring is properly routed and shielded according to local electrical codes to minimize EMI.

FAQ

What is the IC693MDL230?

The IC693MDL230 is an 8-point 120 VAC isolated input module for the GE Series 90-30 PLC system, used to interface field devices with the controller logic.

Can this module be used with DC power?

No, this module is specifically designed for AC input signals and cannot be used with DC power sources.

How are the inputs isolated?

The module provides 1500 volts RMS isolation between the field side and the logic side, and 500 volts RMS isolation between individual input points.

What do the LED indicators signify?

The eight green LEDs on the front panel indicate the ON/OFF status of each corresponding input point. When an LED is lit, the input point is in the ON state.
