Description

Product Description

The IC694MDL741 discrete output module is part of the GE Fanuc / Emerson PACSystems RX3i family, designed to deliver reliable DC switching for industrial control systems. It provides 16 positive-logic outputs organized into two electrically isolated groups, allowing flexible wiring and load distribution across field devices.

Each output channel is capable of driving standard 12 VDC or 24 VDC loads, making the module suitable for actuating relays, solenoids, indicator lamps, and other DC-powered equipment. Optical isolation and fast switching performance ensure dependable operation in electrically noisy environments.

FAQ

Q: Are the outputs sourcing or sinking?
A: The module uses positive logic, meaning it provides sourcing outputs.

Q: What is the maximum load current per channel?
A: Each output can supply up to 0.5 A, with a maximum of 2 A per group.

Q: Can different voltage levels be used across groups?
A: Yes, the two groups are electrically isolated, allowing independent wiring configurations.

Q: How fast are the outputs?
A: The module supports switching times of 2 ms or less for both ON and OFF transitions.
