Product Overview
When a Series 90-30 line goes down, every hour of downtime costs money. The IC693MDL241D is the 16-channel discrete input module that keeps those lines running. Built by GE Fanuc / GE Intelligent Platforms and now owned by Emerson, this revision D module carries 16 input channels in a single slot, so you get dense field sensing without giving up rack space.
This module is discontinued (End of Sale), which makes availability the real question. Oil AutoTech specializes in fast-dispatch spares for oil, gas and industrial automation, so you can secure a tested replacement instead of redesigning a working panel.
Technical Specifications
The IC693MDL241D accepts 24 VAC or 24 VDC at its rated voltage, with an input voltage range of 0 to 30 VAC or 0 to 30 VDC at 50/60 Hz. That flexibility matters on mixed-voltage plants where AC pilot devices and DC field switches share the same cabinet.
Each channel draws roughly 7 mA at rated voltage, a light load that suits long field runs. The module supports positive or negative logic, so it adapts to sinking or sourcing field devices without extra hardware. All 16 channels sit in one group with a single common, which simplifies terminal planning.
Field-to-logic isolation is rated 1500 V RMS. That barrier protects the backplane from transients and ground loops common in process areas. Operating temperature spans 0 to +60°C ambient, covering typical control-room and sheltered cabinet conditions.

Where It Fits
Oil and gas operators use the IC693MDL241D to read limit switches, pressure and flow contacts, and valve position feedback. Its 24 VAC/VDC rating matches the field voltages already present on many skids and pump stations, so retrofits stay simple.
Water treatment and packaging lines rely on the same module for high-density status monitoring. With 16 channels in one slot, a single module replaces several lower-density cards, freeing rack space for future expansion.
Replacement and Upgrade Guidance
Because this module is discontinued, plan replacements before a failure stops production. Confirm your revision level, channel count, and logic configuration match your existing installation. The IC693MDL241D uses positive or negative logic, so verify how your field devices are wired before swapping modules.
For integration, confirm rack compatibility and terminal assignments against your Series 90-30 documentation. If your system uses a fieldbus network, wiring may require an external gateway or connection module — check cables and gateways with your supplier first.

Practical Maintenance Notes
Inspect modules periodically for loose terminals, dust buildup, and heat stress. Keep cabinet ambient within the 0 to +60°C operating range, and follow the manufacturer’s safety manual for all service work. Stocking a spare IC693MDL241D shortens recovery time when a channel fails.
