Signal relay 2
PELV: The output is galvanically separated from other circuits. Therefore, you can connect the supply voltage or protective extra-low voltage to
the output as desired.

Function
Signal relay 1. LIVE or PELV.
Signal relay 2. PELV only.
Digital input/output, configurable.
Open collector: Maximum 24 V resistive or inductive.
Analog input:
0-20 mA or 4-20 mA
0.5 - 3.5 V, 0-5 V or 0-10 V.
Digital input, configurable.
Digital input 1 is factory-set to be start or stop input where an open circuit results in stop. A
jumper has been factory-fitted between terminals 2 and 6. Remove the jumper if digital input 1
is to be used as external start or stop or any other external function.
Power supply to a potentiometer or sensor.
Protective earth.
GENIbus, A (+).
