IC693MDL931 GE Fanuc 8-Point NC Form C Relay Output

Product Overview

The GE Fanuc IC693MDL931 is an 8-point isolated relay output module designed for the Series 90-30 PLC environment. It is distinguished by its "Isolated" architecture, meaning each output point has its own common return, providing maximum electrical separation between channels. With a highly compact net weight of only 0.2 kg (0.44 lbs), this module delivers significant switching power. It supports Form C and NC relay contacts, making it suitable for applications that require normally closed logic or changeover capabilities for 24VDC or 120/240VAC loads.

Core Technical Advantages

The IC693MDL931 is built for high-capacity performance, featuring a maximum resistive load rating of 8 Amps per output. This 0.2 kg lightweight module offers professional-grade protection with a 1500 VAC isolation rating (for 1 minute) between field points and the PLC backplane. It consumes a mere 6 mA from the 5V bus, while the relay coils draw 110 mA from the 24V bus when fully energized. Its rapid response time of 15 ms and low leakage current (1 mA max) ensure precise and reliable operation for safety-interlock systems and motor starter control.

Technical Specifications

Installation & Thermal Management

Installation of the GE Fanuc IC693MDL931 is seamless within any Series 90-30 I/O slot. Despite its 0.2 kg frame, the module can carry up to 20 Amps total for UL installations. It is crucial to monitor ambient temperature, as the total module current may require derating in hotter environments to prevent internal component fatigue. Wiring should account for the isolated nature of the points; because each output has an independent return, engineers can mix different power phases or DC sources across the eight channels without risk of cross-talk or short circuits.

Engineering Advantages

The IC693MDL931 is an engineer's choice for complex signaling where isolation is paramount. The 8A inrush current capacity allows it to handle the initial surge of inductive loads like solenoids or small contactors. The module's 0.2 kg design includes Form C relays, providing both a normally open and normally closed contact for each point, which is essential for "fail-safe" logic applications. Furthermore, the point-to-point isolation eliminates the need for external interposing relays in many scenarios, saving both cost and panel space while maintaining 250 VAC continuous isolation.

Technical FAQs

Q1: What is the physical weight of the GE Fanuc IC693MDL931?
A1: This module has a net weight of 0.2 kg (0.44 lbs), making it one of the lighter yet most robust relay modules in the Series 90-30 lineup.

Q2: What is the benefit of an "Isolated" relay module?
A2: Isolation allows each of the 8 relay outputs to operate with its own dedicated common, enabling you to switch different voltages or different phases on the same module safely.

Q3: Does the IC693MDL931 support high-speed switching?
A3: It has a response time of 15 ms for both On and Off states. While typical for mechanical relays, it is best suited for general control logic rather than high-speed pulse applications.
