Interface safety relays

Safety relays from the Interface range are for monitoring emergency stop circuits, safety door circuits and two-handed control systems.

The series includes options for one or two channel control, man-ual or automatic activation and a full range of relay output configurations.

Special modules are available for contact expansion, light barriers and process control (SIL 3). Modules with safe time function are also available for dynamic processes, allowing precise operation up to safety category 4. All connections are pluggable and coded, and are now available with optional spring cage or screw connection technology.

The modules have reinforced insulation between input and output and between the enable and signal circuits.

Special modules to SIL3/IEC 61508 standard are available for applications in combustion plants and process technology.
