SAFETY
MONITORING RELAY. 2NC and 1NO CONTACTS.

The VIPER
SCR-21-i safety monitoring relay with added diagnostics from IDEM had been
designed and manufactured in the United Kingdom to meet the latest safety
standards and offer enhanced LED diagnostics and simplified wiring.

Applications
include the monitoring of safety interlock switches (guard door monitoring),
emergency stop devices and sensors.

The
SCR-21-i internal logic uses force guided relays to achieve cross monitoring,
this ensures that a single fault does not lead to the loss of the safety
function and that all faults are detected at or before the next safety demand.

FEATURES:

·       Outputs 2NC contacts and 1NO contact.

·       Feedback circuit to monitor external contacts.

·       Easy diagnosis of status via visual indication of
LEDs.

·       Up to PLe, SILCL 3, Category 4.

·       Monitored manual or automatic start.

·       Single and dual channel operation.

·       Output expansion units available to increase number
of outputs.
