Design
The solid-state safety relays can be used in EMERGENCY-STOP
devices to EN 418 and in safety circuits to EN 60204-1 (11.98),
for example, for moving covers and protective doors.
Depending on the device type and the external circuit, the
maximum category that can be achieved is Category 4 of
EN 954-1 or SIL 3 according to IEC 61508.

The internal circuit is configured with redundancy and
diversity. The processors monitor each other dynamically.
The output drivers are also redundant and diverse. They are
monitored by a cyclic self-test.
All sensor signals are dynamically tested. This enables faults
to be detected on the sensors, wires (cross-circuit) etc.
The field-effect transistor (FET) is switched by both
processors. The output driver must be activated
simultaneously by one of the two processors. Only then is the
voltage connected safely from power supply terminal A1 to
output terminals 14 + 24.
All solid-state switches (FET + output driver) are dynamically
monitored by the processors.
The required functionality (1-channel or 2-channel), monitored
start or autostart, EMERGENCY-STOP, protective door and
cascading is set by means of jumpers at the connection
terminals.

1) The outputs are only safe when an external contactor is used.
Installation
For snap-on mounting on 35 mm standard mounting rail
according to EN 50022. Screw fixing is also possible for the
devices by means of 2 additional 3RP19 03 push-in lugs.
