Description
● 90 mm, P-01 housing, DIN-Rail
mounting
● Relay outputs, positive-guided:
– 3 safety contacts (N/O)
● Connection between base unit,
control unit and between
expander moduls via P-01-Bus
through connector plug on the
rear of the unit.
● LEDs for channel 1/2, supply
voltage and fault
Function Description
PNOZ po3.3p supplies 3 safety
contacts for the modular safety
system PNOZpower. It must be used
in conjunction with a base unit or
PNOZ e1p control unit
The output contacts can be opened
via an external start/stop input. This
enables loads to be switched under
normal operating conditions, without
energising the E-STOP circuit.
