GE IC693MDL940H – Series 90-30 16-Channel Relay Output Module

In stock

Product Introduction:

The IC693MDL940H is a high‑reliability relay output module engineered by GE Fanuc (now Emerson) for the Series 90-30 PLC platform. It provides 16 normally‑open relay contacts to switch DC or AC loads, serving as an electromechanical interface between the PLC’s low‑voltage logic and high‑power field devices. Designed for heavy‑duty industrial environments, it delivers superior isolation, noise immunity, and load‑driving capability.

Key Features

16 High‑Power Relay Outputs: Each channel handles up to 2A resistive loads for direct control of solenoids, motor starters, and contactors.
4‑Way Electrical Isolation: Four isolated groups eliminate cross‑group interference and enhance safety in mixed‑voltage systems.
Wide Voltage Compatibility: Supports both DC and AC loads (5–250VAC/5–30VDC) for maximum application flexibility.
LED Status Indicators: Individual LEDs for each channel enable immediate visual diagnosis of output status.
Hot‑Swappable: Allows replacement during system operation to minimize downtime.
Robust Construction: Industrial‑grade housing withstands vibration, shock, and harsh environmental conditions.

Application Scenarios

Factory Automation: Controls solenoid valves, pneumatic actuators, and motor starters on assembly lines.
Process Control: Drives pump relays, valve actuators, and alarm beacons in water/wastewater and chemical plants.
Building Automation: Governs HVAC dampers, fan motors, and lighting contactors in commercial facilities.
Power & Energy: Controls auxiliary relays and circuit breakers in power distribution systems.
