GE IC694MDL940 – PACSystems RX3i 16-Channel Relay Output Module

In stock

Product Introduction:

The IC694MDL940 is a high‑reliability relay output module for the Emerson PACSystems RX3i PLC platform, providing 16 normally open (NO) electromechanical relay contacts. It switches DC or AC loads up to 2A per channel, 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 for factory automation, process control, and building automation applications.

Key Features

16 High‑Power Relay Outputs: Each channel handles up to 2A resistive loads for direct control of solenoids, motor starters, contactors, and heaters.
4‑Way Electrical Isolation: Four isolated groups eliminate cross‑group interference and enhance safety in mixed‑voltage systems (DC/AC).
Wide Voltage Compatibility: Supports both DC (5–30V) and AC (5–250V) loads for maximum application flexibility and global deployment.
LED Status Indicators: Individual green LEDs for each channel enable immediate visual diagnosis of output status and fault detection.
Hot‑Swappable: Allows replacement during system operation to minimize downtime in critical applications.
Rugged Construction: Industrial‑grade housing withstands vibration, shock, and harsh environmental conditions (dust, moisture) for long‑term reliability.
High Inrush Current Capability: Handles up to 5A inrush current per channel for inductive loads (motors, transformers).

Application Scenarios

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