• Mounting: Occupies one I/O slot in a 5-slot or 10-slot baseplate

Functional Features

• Reactive Input Circuits: Each of the 16 input points uses a resistor and capacitor network for signal conditioning. Current flow into an input results in a logic 1 status in the %I table.

• Wide Input Device Compatibility: Input characteristics are compatible with pushbuttons, limit switches, and electronic proximity switches.

• LED Status Indication: Two horizontal rows of eight green LEDs on the module top panel provide ON/OFF status for each point. The top row (A1-A8) corresponds to points 1-8, and the bottom row (B1-B8) corresponds to points 9-16.

• High-Voltage Identification: The insert card inside the hinged door features a red color-coded left edge to indicate a high-voltage module.

• Field-to-Logic Isolation: Provides 1500 Volts RMS isolation between field wiring and the PLC backplane to prevent high-voltage surges from damaging logic components.

• Documentation Insert: A hinged door includes a dual-purpose insert; the inner surface displays circuit wiring information, and the outer surface allows recording of circuit identification data.

Application Scenarios
This module is deployed in industrial automation systems where 120 VAC field devices must interface with the Series 90-30 PLC:

• Motor Control Center (MCC) Monitoring: Interfaces directly with 120 VAC contactor auxiliary contacts to monitor motor running status without requiring intermediate relays.

• Discrete Device Interfacing: Connects pushbuttons, selector switches, and limit switches to the PLC for machine control and operator input.

• Proximity Sensor Integration: Reads signals from electronic proximity switches for part present detection and position sensing.

• Legacy Equipment Retrofits: Enables older machinery with 110/120 VAC control circuits to integrate with modern PLC-based automation systems, preserving existing field wiring.

Important Clarification on Data Inconsistency
Search results for IC693MDL240 contain significant contradictions from various third-party sources. The specifications above are drawn from the most consistent descriptions identifying this product as a 16-point 120 VAC discrete input module for the Series 90-30 PLC. Several sources present conflicting information, including claims that the module is a power supply with 24 VDC input or an analog output module. Specifications such as dimensions, weight, input current, and operating temperature also vary across distributor websites. For precise integration and replacement planning, consult official GE documentation or examine the module label directly.
