Configured for isolated discrete switching in VersaMax control networks, the GE Fanuc IC200MDL940E (IC200MDL940E Relay Output Module) provides direct physical/electrical execution. This hardware component utilizes onboard mechanical relays to switch field-side AC or DC loads, effectively isolating the controller logic from field-level potential.

Suffix Breakdown & Model Matrix

The IC200MDL940E is a multi-point relay output assembly. The "E" suffix designates the current hardware revision level, which includes optimized mechanical relay contact ratings and backplane interface circuitry compliant with the VersaMax I/O platform standards.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IC200MDL940E utilizes the VersaMax backplane bus to execute relay state changes commanded by the host controller. Integration into deterministic networks requires precise mapping of output data words, accounting for the inherent mechanical switching latency associated with relay-based outputs. Users must ensure that the software scan rate is synchronized with the relay response time to maintain deterministic operation across the I/O array. Firmware compatibility must be verified against the host I/O scanner to ensure full support for the 16-point output mapping structure.

Frequently Asked Questions

Q: Does the relay output module support inductive load switching?

A: Yes, but the use of external suppression (e.g., MOV or RC networks) is required to prevent contact pitting and excessive arcing, which would otherwise reduce the mechanical service life of the relays.

Q: What is the maximum contact rating for this relay module?

A: The module is designed for standard low-to-medium power industrial loads; users should consult the technical manual to ensure the current and voltage ratings are not exceeded, as mechanical contact failure may occur under overload conditions.

Field Installation Guidelines

• Ensure the terminal base is securely mounted to the DIN rail before installing the module electronics to ensure proper electrical contact with the backplane.
• Route field wiring through dedicated conduits, keeping high-current power lines separated from sensitive communication or signal wiring to prevent electrical noise coupling.
• Ground the module chassis at the designated earth point to ensure proper shielding and protection against static discharge.
• Verify that the total load current per common does not exceed the maximum rating for the internal relay common bus to prevent overheating.
• Confirm that the terminal block locking mechanism is fully engaged to prevent accidental signal disconnection due to vibration in the industrial cabinet environment.
