b Common contact
The power supply module (the gateway or PLC, for example) must provide a
minimum supply voltage to the relay output module. This voltage depends on
the ambient temperature, as shown in the table below:

NOTICE
In order for the relay coil to pick up correctly, the relay output
module needs a minimum supply voltage.
