Overview
The REL52813 is a Schneider Easergy VIO12ACSE analog temperature module that accepts 12 RTD inputs plus one PTC, with four 4 mA analog outputs and four 4 mA analog inputs, all on a 24 V DC supply and a Serial link Fiber optic interface.
Schneider discontinued the REL52813 on 2024-12-01; remaining units are available through surplus and broker channels rather than current distribution, so an RFQ confirms actual quantity and lead time for a last-time-buy or line-down need.
Selection vs REL52811
The REL52813 adds a PTC input alongside the 12 RTD inputs, while the REL52811 carries 12 RTD inputs only and runs on a 230 V AC supply instead of 24 V DC. Pick the REL52813 when the BOM requires the extra PTC channel and a 24 V DC control voltage; the REL52811 suits a 230 V AC panel with no PTC need.
