mounting
● Positive-guided relay outputs:
– 4 safety contacts (N/O)
– 1 auxiliary contact (N/C)
● Connection for feedback control
loop
● Delay-on energisation and delayon de-energisation can be
programmed
● Single or dual-channel operation

Function Description
PZE 5V is used to increase
the number of safety contacts
available and the timed delay
switching of an E-STOP command
for
● E-STOP relays
● Safety gate monitors
● Two-hand relays
All base units must have a feedback
control loop.
