Details

TCA-DI digital input safety barrier       

·   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 TCA-DI 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).

·   Available in multiple channel styles (optional).

·   Line fault detection function (optional).

·   This product requires a separate DC power supply. Power-input-output and isolation between channels.
