X1-NIS-RLI-01-S

SIL3 24/220-Vdc/Vac Voltage Transistor-Out Detector

The Vdc/Vac Voltage Detector X1-NIS-RLI-01 module is a unit suitable for applications requiring SIL 3 level in safety related systems for high risk industries. The module is able to reflect the presence of a 24 to 220 Vac/Vdc nominal input signal to the output by closing an optically coupled open-collector transistor, which guarantees reinforced insulation to the field. The input voltage presence is also indicated by a yellow LED on the front panel. DC signals have a separated interface for a faster response time. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.
