It supplies a 26 V RMS, 2,381 Hz reference to excite the resolver and reads the resolver’s 11.8 V RMS sine and cosine feedback signals, returning a digital representation of position to the PLC. The module provides 12‑bit resolution per revolution with a 2‑bit revolution counter, enabling precise tracking of angular position across revolutions. Sampling rate is configurable from 500 microseconds to 32.767 seconds, with an external strobe input to synchronize with external events and the option to interrupt on every sample. Power is supplied from 120\/240 VAC, and the unit is rated for operation from 0 to 50°C and 0 to 95% relative humidity non‑condensing. Faceplate indicators include ISP OK, CCLK OK, FDBK OK, DIRECTION, and a green OK LED, helping operators monitor operation at a glance. Connections are on a front‑face terminal block with -TRIG+, -COS+, -SIN+, and REF-OUT+, and the module plugs into the AutoMax backplane in the DCS 5000 rack, secured by two mounting brackets.\u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"New Surplus No Box","offer_id":46285441401066,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/reliance-electric-57c411-resolver-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
