Order now IC693MDL930 GE Fanuc Series 90-30 Isolated Relay Output Module
Order now IC693MDL930 to deploy incredibly robust and versatile load switching across your manufacturing facility. The GE Fanuc IC693MDL930 is a premium 8-Point Isolated Relay Output Module explicitly designed for the Series 90-30 Programmable Logic Controller (PLC) architecture. Unlike solid-state transistor modules, this unit relies on heavy-duty, electromechanical Form-A (Normally Open) relay contacts. This design provides the ultimate in load flexibility, allowing a single module to switch a diverse mix of AC and DC voltages without requiring external interposing relays. Each of the 8 output points is completely electrically isolated from the others, meaning you can control a 120 VAC motor contactor on channel one, and a 24 VDC hydraulic solenoid on channel two, with absolutely zero risk of cross-contamination. Capable of handling up to 4 Amps of continuous current per point, the IC693MDL930 is the definitive choice for applications requiring high-current switching, electrical isolation between disparate power phases, and undeniable mechanical reliability in severe industrial environments.

Expert Maintenance and Output Protection Tips
While the internal electromechanical relays of the IC693MDL930 are exceptionally robust, they are not immune to the laws of physics. When switching highly inductive loads—such as large motor starter coils, heavy mechanical brakes, or industrial solenoids—a massive voltage spike is generated the moment the relay contacts open. If left unsuppressed, this electrical arc will rapidly pit and erode the silver-alloy contacts, drastically shortening the module’s lifespan. To maximize the longevity of your hardware, it is an absolute industry best practice to install external suppression devices directly across the field loads. For AC loads, utilize properly sized RC (Resistor-Capacitor) snubber networks. For DC loads, install reverse-biased flyback diodes. Furthermore, be aware that this module does not contain internal field-side fusing. You must provide external fast-acting fuses on the terminal blocks to protect the internal relay traces from dead-short conditions on the factory floor.
Frequently Asked Questions (FAQs)
Can the IC693MDL930 be used for high-speed PWM or pulse applications? No. Because this module uses mechanical relays, it has a typical response time of 15 milliseconds. It is strictly designed for standard ON/OFF logic and will quickly degrade if subjected to high-frequency switching or rapid pulsing operations.
Why is my load remaining powered even when the PLC output is OFF? If an output remains powered when the logic is off, it is highly likely that the internal relay contacts have micro-welded themselves closed due to an unsuppressed overcurrent spike or an inductive arc. The module will need to be replaced and external snubbers installed.
Do the 8 points share a common power source? No, and this is the primary advantage of the IC693MDL930. Every single point has its own isolated input and output terminal, allowing you to run completely separate and distinct voltage sources through each individual relay.
