31CSP2E24 - SEQUENCE RELAY CSP2E 24VAC

Why Choose the 31CSP2E24?

The Lovato 31CSP2E24 is a start-up priority change relay designed for reliable duty/standby management. This plug-in version features two relay outputs and operates from a 24VAC supply for straightforward integration. Housed in an 11-pin socket format (S11), it enables the possible starting of a stand-by motor to maintain continuity. Built on the CSP2E platform, it delivers robust performance in industrial control panels where automated changeover and sequencing are essential.

Engineered for harsh environments, the 31CSP2E24 withstands impulse voltages up to 4 kV and provides an Ith of 5 A to align with IEC/EN 60255-5. It operates from -20 to +60 °C with storage from -30 to +80 °C, and weighs just 150 g for compact installations. With its 11-pin plug-in housing, maintenance and replacement are fast, supporting minimal downtime and dependable service.
