• Configurable analog input support for ±10 V or 4–20 mA signals.
• Robust contact ratings for switching applications up to 5 A at 250 V AC/DC.

Technical Specifications

Installation Guidelines

• Ensure all power is disconnected from the drive system before attempting to install or remove the interface board.
• Handle the module using proper ESD (Electrostatic Discharge) protection measures to prevent damage to sensitive internal circuitry.
• Verify that the mounting environment is free from excessive dust, moisture, and corrosive gases.
• Ensure adequate ventilation around the drive cabinet; derate performance if the ambient temperature exceeds 40 degC.
• Check all terminal connections for tightness and ensure wires are properly routed to avoid interference from high-voltage power cables.

FAQ

Is this module compatible with other SIMOVERT series?

This specific board is identified by order code C98043-A7002-L4-12 and is often cross-referenced with spare model 6RY1703-0DA02. Please verify your existing drive's part number or consult your system manual to ensure full compatibility with your specific drive revision.

What should I do if the ambient temperature exceeds 40 degC?

The module is rated for operation up to 55 degC; however, you must apply appropriate derating to the performance specifications if the ambient temperature in the cabinet rises above 40 degC to prevent thermal stress on the components.
