TCA-SDI digital input safety barrier (with SIL functional safety)          

·  Functional safety meets SIL 2 of IEC 61508. 1 in 1 out, 1 in 2 out, 2 in 2 out. Contact switch, NAMUR proximity switch, OC signal or level signal, intrinsically safe input. Line fault detection alarm function. Relay contact output, OC signal or level signal output.

·  The DSA-SDI digital input barrier is suitable for OC, level, contact switch or NAMUR proximity switch input in hazardous areas on site. After isolation, it is transmitted to the control system of the safety zone or other instruments by relay contact output (or OC output, level output).

·  Functional safety up to SIL 2 of IEC 61508.

·  Available in multiple channel styles (optional).

·  Line fault detection function (optional).
