Product Overview
When a Series 90-30 line goes down, every hour of downtime costs money. The IC693MDL240G is a 16-point, 120 VAC discrete input module built for GE Fanuc / GE Intelligent Platforms Series 90-30 racks. Emerson now owns the line, and this module remains a practical spare for plants that still run 90-30 hardware.
Each unit packs 16 inputs into one group with a single common, so field wiring stays simple. If you maintain oil, gas, or industrial automation panels with legacy GE control, this is the kind of spare you want on the shelf before you need it.
Key Parameters at a Glance
| Specification | Value |
|---|---|
| Input points | 16, 120 VAC, one group with single common |
| Input voltage range | 0 to 132 VAC, 50/60 Hz |
| Input current | 12 mA typical at rated voltage |
| On-state voltage | 74 to 132 VAC |
| Off-state voltage | 0 to 20 VAC |
| Isolation | 1500 V RMS, field side to logic side |
| Backplane current | 90 mA from 5 V bus (all inputs on) |
| Operating temperature | 0 to +60°C ambient |
What the Specs Mean in Practice
The 74 to 132 VAC on-state window gives you margin against supply sag. A 120 VAC signal that dips slightly still registers as ON, which matters in plants where voltage fluctuates. The 0 to 20 VAC off-state threshold keeps leakage from false-triggering an input.
Response times are 30 ms maximum ON and 45 ms maximum OFF. That suits limit switches, pushbuttons, selector switches, and relay contacts — not high-speed counting. Isolation of 1500 V RMS between field and logic sides protects the backplane from field transients.
Backplane draw is 90 mA from the 5 V bus with all inputs on. Check your power budget when populating a full rack.
Where It Fits
Oil and gas facilities often keep Series 90-30 racks running well past their design life. This module reads status from valve position switches, pump run contacts, and level switches on 120 VAC control circuits.
In water treatment and packaging lines, the single-common grouping simplifies wiring for panels with many discrete devices sharing a common return. The IP20 rating suits clean cabinet environments; keep it out of washdown areas.
Installation Notes
Mount the module in a Series 90-30 rack slot and land field wiring on the front terminal block. Keep 120 VAC field wiring separated from low-level analog and communication cables to reduce noise. Verify the common grouping matches your field device arrangement before terminating.
Operating ambient is 0 to +60°C. Provide cabinet ventilation if surrounding equipment runs hot. Storage range is -40 to +85°C, and humidity tolerance is 5 to 95% non-condensing.
Lifecycle and Sourcing
This module is legacy/obsolete in aftermarket listings, and the official Emerson EOS date is not verified. That makes availability the real question. Oil AutoTech supplies ready-to-ship spares for oil, gas, and industrial automation, with hands-on help matching the right module to your rack. Contact Oil AutoTech today for pricing and availability.
