GE IC693MDL231 240 VAC Isolated Input Module – Series 90-30 PLC
When a discrete input module fails on a live production line, the consequences are immediate and costly: the PLC loses visibility into field devices, safety interlocks go blind, and operators are forced into manual override — or a full shutdown. In high-voltage AC environments running at 240 VAC, the risk compounds further, as incompatible or degraded input cards can introduce ground loops, false signals, or outright electrical faults. The GE IC693MDL231 eliminates this vulnerability by providing eight fully isolated 240 VAC discrete input channels, each galvanically separated to protect the controller backplane from field-side transients and noise.
Within GE’s IC693 Series 90-30 family — one of the most widely deployed modular PLC platforms in North American and global industrial automation — the IC693MDL231 occupies a critical niche: it is the designated solution for high-voltage AC field wiring where isolation is non-negotiable. The Series 90-30 platform has been a backbone of process control, discrete manufacturing, and utility automation for decades, and the IC693MDL231 continues to be sourced as both an OEM build component and a maintenance replacement across thousands of installed systems worldwide.

Key Features & Benefits
- 8-Point High-Voltage AC Input: Handles 240 VAC field signals directly — no interposing relays or signal converters required.
- Full Galvanic Isolation: Each input channel is optically isolated from the PLC backplane, protecting the CPU and other modules from field-side voltage spikes and ground potential differences.
- Drop-In Series 90-30 Compatibility: Slots directly into any IC693 rack without hardware modification, minimizing downtime during replacement.
- Noise Immunity: Designed for electrically noisy industrial environments — motor drives, contactors, and high-current switching do not induce false input states.
- Proven Field Reliability: Part of a platform with decades of installed-base history in demanding industrial applications.
- Simplified Wiring: Accepts standard 240 VAC field wiring conventions, reducing commissioning time for maintenance teams.
Industry & Equipment Applications
- Power Generation & Utilities: Monitoring high-voltage limit switches, breaker status, and relay feedback in substation and generation control panels.
