Relay Interface and Protection Signal Handling

The MES114 expands Sepam protection relay I/O capability through direct connection of external status signals and command circuits. The module receives 24...250 V DC logic inputs and provides relay contacts for control and indication functions.

The control relay output supports switching circuits with a continuous current rating of 8 A, while the indication relay outputs support continuous current operation up to 2 A. Relay characteristics include defined making capacity limits and breaking capacities according to AC and DC load conditions.

The module uses Schneider Electric Sepam I/O architecture for integration with protection relay functions, allowing external circuit states to be processed by the connected Sepam device.

Field Installation Guidelines

Install the MES114 module according to the Sepam relay hardware configuration requirements. Verify that the relay platform supports the additional I/O module before mechanical installation.

Use suitable field wiring practices for digital input and relay output circuits. Separate signal wiring from high-current conductors where possible, and maintain proper grounding and shielding methods for control cabinets containing protection equipment.

Connect external circuits using the specified screw-type terminal connections and verify cable sizing compatibility before energizing the module. Confirm relay output wiring polarity and load characteristics during commissioning.

The module was discontinued on September 3, 2024, with end-of-service scheduled for September 3, 2026. Schneider Electric recommends the PowerLogic P5 Protection Relay range as the replacement product range.
