Discrete Output Module | GE IC200MDL330B

The GE Fanuc IC200MDL330B is a 16-channel discrete output module engineered for the VersaMax I/O platform. Operating on a 24 VDC nominal supply, this sinking (NPN) module controls DC field devices such as solenoids, relays, and indicator lamps. It features dual-group circuit isolation, electronic short-circuit protection, and channel-level LED diagnostics for reliable automation system operation.

Channel Configuration and Switching Performance

The module features 16 NPN sinking output channels organized into 2 isolated groups of 8 channels each. Each channel delivers up to 0.5 A output current, supporting up to 4 A per group and a total module capacity of 8 A. With fast output response times under 1 ms for both ON and OFF states, the module supports switching frequencies up to 500 Hz for resistive loads.

Protection Features and Electrical Limits

Built-in protection mechanisms include electronic short-circuit protection, over-temperature protection, and transient voltage suppression across all outputs, with automatic protection reset following fault removal. The unit draws 120 mA from the 5 VDC backplane bus alongside an external 80 mA 24 VDC field supply, maintaining a maximum power dissipation of 2.5 W.

Physical Characteristics and System Integration

Housed in an IP20 enclosure, the module mounts directly onto VersaMax I/O bases and accepts field terminal wiring sizes from AWG 24 to AWG 14 (0.2 to 2.5 mm2). Front-panel diagnostic LEDs include 16 green channel status indicators and a dedicated power LED. System setup and parameterization are managed via VersaPro or Machine Edition Logic Developer configuration software.

Frequently Asked Questions

Q: What is the output type of the GE IC200MDL330B VersaMax module? A: The IC200MDL330B features 16 NPN sinking outputs, which switch the negative side of connected 24 VDC loads to circuit common.

Q: How does the IC200MDL330B reset when a short circuit or over-temperature condition occurs? A: The module incorporates built-in protection circuits that automatically reset output operation once the fault condition is cleared and internal temperatures stabilize.

Q: How is the total output current structured across the module? A: The module is divided into 2 isolated groups of 8 channels. Each group supports up to 4 A maximum, allowing a total maximum load current of 8 A across all 16 channels.
