I/O modules

Versatile Relay Control for VersaMax Systems

The GE IC200MDL940 output module provides 16 individually isolated Form A relay outputs for the VersaMax I/O platform. This module directly drives AC and DC loads, eliminating the need for external interposing relays. Manufacturing and process control applications benefit from this module’s robust switching capabilities.

Output Specifications and Electrical Ratings

This output module features 16 normally open relay contacts, each rated for 2.0 amperes of continuous current. The outputs support a wide range of voltages, from 0 to 125 V DC and 0 to 265 V AC. Each output point includes an individual LED indicator for convenient visual status verification. Furthermore, the module provides full isolation between channels, ensuring reliable operation.

Relay Design and Protective Features

The GE IC200MDL940 employs fixed coil relays with moving armatures and silver alloy contacts. This design ensures reliable switching over an extended operational life. The module provides 1500 V AC isolation between input logic and frame ground, protecting the backplane from electrical surges. Furthermore, the module does not include internal snubbers or fuses; users should install external protection as needed.

Physical Design and Installation

This output module features a compact design suitable for VersaMax I/O racks. The front panel includes a lock/unlock lever for secure module retention. A green OK LED indicates backplane power presence, while individual green LEDs per point show output status. The module draws primary power from the backplane, but external power sources must supply the load circuits.

System Integration and Addressing

You can install this output module in any VersaMax I/O rack with compatible CPU or NIU. The module maps its 16 output points to the controller’s output table. A logic “1” from the CPU closes the corresponding relay contact. Furthermore, the module supports hot-swap capability, enabling module replacement without system shutdown.

Application Guidelines and Environmental Ratings

This output module operates reliably from 0°C to 60°C and carries a Class 1 Division 2 rating for hazardous locations. Typical applications include solenoid control, contactor switching, and indicator lamp actuation. For inductive loads, limit the switching frequency to 20 cycles per minute. Always use appropriately sized external fuses to protect output circuits.
