It provides a galvanically isolated RS-422 pulse-train output with a 50 mA maximum load, enabling precise frequency control for motion devices while remaining isolated from the E-bus. The terminal converts a binary input into a variable-frequency pulse train and supports incremental encoder simulation, useful for testing drives and controllers without a physical encoder. As an EtherCAT terminal, it communicates over the E-bus while delivering the output signal to the field device with galvanic isolation, improving noise immunity in compact automation cabinets.\u003c\/p\u003e\u003c\/div\u003e","brand":"Beckhoff","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46266728317162,"sku":null,"price":181.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-073.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/beckhoff-el2521-io-module","provider":"GTG Hardware","version":"1.0","type":"link"}
