SIL and PL are dependent on the upstream safety module).
- Possibility for 1- or 2-channel control.
- Connection of input channels of opposite potentials.
- Output contacts: 5 NO safety contacts, 1 NC auxiliary contact, 1 NC feedback
contact.
- LED indicators for switching state of the channels 1 and 2.
- Screw terminals or plug-in terminals with screw connections or spring terminals (de-
pending on the model).
- Snap-mounting on DIN rails.
