Description
Overview
The IC200MDL750 is a high-density discrete output module designed for the GE Fanuc / Emerson VersaMax I/O system. It provides 32-channel sourcing (positive logic) DC outputs for distributed control applications requiring reliable switching of field devices such as solenoids, relays, indicators, and similar DC loads.
The module installs on VersaMax I/O carrier bases and communicates through the backplane while using an external field power supply for load energization.
Functional Architecture
The output structure is divided into two independent banks of 16 channels, allowing structured field wiring and load separation.
Key functional characteristics:
-
32 sourcing DC output channels
-
Positive logic high-side switching configuration
-
Two isolated 16-point output groups
-
Individual LED status indicators per channel
-
OK and Field Power diagnostic LEDs
-
Backplane-powered control logic with external field supply
Electrical Performance Specifications
-
Output Voltage Range: 10.2 to 30 VDC (12/24 VDC nominal systems)
-
Output Current: 0.5 A per channel (resistive load)
-
Inrush Current Capability: up to 2 A for 100 ms per point
-
Backplane Current Consumption: approximately 90 mA at 5 VDC
-
Switching Speed:
-
Turn ON: 0.2 ms
-
Turn OFF: 1.0 ms
-
Output Type: DC sourcing (positive logic only)
These parameters support fast-response discrete control in compact I/O architectures.
Isolation and Protection
-
Field-to-backplane isolation: 250 VAC continuous
-
Dielectric withstand: 1500 VAC for 1 minute
-
Group isolation between two 16-channel banks
-
No point-to-point isolation
Inductive loads should be externally suppressed using flyback diodes, RC snubbers, or equivalent protection methods to ensure long-term reliability.
