IDEMSafety module product details

IDEMSafety module expansion unit

Professional Series IDEM VIPER Safety module with pluggable and screw terminal blocks. The safety module includes an expansion unit. Relays can be wired directly to increase the number of safe output contacts. Designed to meet ** safety standards and provide enhanced LED diagnostics and simplified wiring. Typical applications include safety interlock switches and emergency stop devices for guard door monitoring.

The expansion unit is designed for use with any SCR base unit. MultipleSEU expansion units can be used together.

SCR-21-i / SCR-31-i / SCR-31P-ito the safety module base unit to increase the number of safe outputscontacts. The expansion module provides instantaneous or delayed outputcontacts.

SEU-31-i uses force-guided relays to provide additional output contacts and fault monitoring

Via feedback contacts from the basic unit, this ensures that a single fault does not lead to loss

of safety functions, and that all faults are detected at or before the next safety demand

relays.When the input of the basic unit safety module output is closedthe expansion unit is activated, and the expansion unit outputis off. When the input is disabled, the expansion unit output opensor in the event of a power failure. Due to feedbackchecking of the expansion unit contacts and the logic of the basic unitthe safety module system requires two internal relays to move tothe open position before the safety module can be reactivated.
