SCR Safety Relays (First Generation)

IDEM’s range of SCR and SEU Safety Relays are designed in accordance with EN60204-1 for safety circuits and can be used in conjunction with Mechanical Interlock Guard Switches, Emergency Stop Switches, Non-Contact Guard Switches or Light Curtains to achieve redundant monitoring and fault checking up to PLe Category 4 ISO13849-1.

Using dual channel circuitry, the SCR-i range monitors safety contacts for opening and closing, short circuits and can be configured to check for correct opening of external machine contactors/relays.

Applications include the monitoring of safety interlock switches (guard door monitoring), emergency stop devices and sensors. For applications requiring time-controlled delay after opening of the guard switch, special time delayed output contacts are available (selectable between 0 to 30 seconds).
