Socket Module with LED and Varistor, Finder 99.02.0.230.98, green indicator, for Series 90

Finder socket module 99.02.0.230.98 is an interchangeable accessory designed for use with Finder Series 90 relay bases. It integrates a green LED indicator for visual status feedback and a built-in varistor to limit voltage transients and provide basic surge suppression. The compact module snaps into the relay socket without altering the relay footprint, allowing retrofit or new installations in control panels and automation systems where clear indication and transient protection are needed.

Advantages

The integrated LED provides immediate visual confirmation of relay coil energization, improving diagnostics and reducing troubleshooting time. The varistor offers protection against short-duration voltage spikes, helping to safeguard the relay coil and associated control circuitry. As an interchangeable socket accessory compatible with Series 90, the module enables easy replacement and flexible configuration of relay assemblies without modifying panel layout.

Suitable for

• Control panels and industrial automation systems using Finder Series 90 relays
• Applications requiring visual coil status indication for maintenance and monitoring
• Environments where basic transient suppression protects relay coils and nearby electronics
• Retrofit projects where compact, drop-in accessory modules are preferred

Key specifications

• Indicator: integrated green LED for coil status visualization
• Surge suppression: built-in varistor for transient voltage protection
• Compatibility: designed to fit Finder Series 90 relay sockets
• Mounting: socket-mounted accessory that installs without changing relay footprint
• Form factor: compact module suitable for panel and DIN-rail relay assemblies

How to use

Install the module into the matching Finder Series 90 relay socket by aligning and pressing it into place until it seats securely. The green LED will illuminate when the relay coil is energized, providing visual confirmation of operation. The varistor operates automatically to clamp transient voltages within its designed characteristics; no separate configuration is required. When replacing or retrofitting modules, ensure power is removed and follow standard safety procedures for working on control equipment.

Recommendations

Use this socket module in applications with nominal coil voltages and transient levels within the varistor’s suppression range. Avoid relying on the module alone for protection in systems subject to frequent or high-energy surges; combine with appropriate surge protection devices and follow equipment manufacturer guidelines for full system protection.
