IDEM Viper Safety Relay with Added Diagnostics

IDEM Viper Safety Relay with Added Diagnostics

Datasheet

The SCR-31-i internal logic uses force guided relays to achieve cross monitoring, ensuring single faults are detected at or before the next demand upon the safety function.

The Viper Safety Relays range from IDEM are designed to meet the latest safety standards and offer enhanced LED diagnostics and simplified wiring.

FEATURES:

• Outputs 3NC contacts and 1NO contact.
• Dual Channel Safety Inputs.
• Up to PLe, SIL 3, Category 4.
• LED Indication for Reset Circuit Status.
• Single or Dual channel operation.
• Monitored Manual or Auto Start/Reset.
• Up to 3 Safety output contacts 1 Auxiliary output contact (Depending on model No.).
• Contactor feedback check.
• Easy diagnosis of status via 6 LEDs.
• 22.5mm DIN rail mounting.
• 24V AC/DC operation.
• Emergency stop and guard interlock monitoring.
• Output expansion units available to increase number of outputs. 

APPLICATIONS:

• Safety interlock switches.
• Emergency e-stop devices.
• Door guard monitoring.

The SCR-31P-i is designed to be compatible with devices offering OSSD/PNP outputs (e.g. safety light curtains, “Z” range switches from IDEM).

 The SCR-31-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.

*Note: For items using PNP inputs such as safety light curtains and safety mats please choose SCR-31P-i model.
