(1) All IO contacts are programmable contacts.
(2)
The max. load of the internal voltage source 24V_OUT is 100 mA.
Maximum total load
The sum of all output currents IO4 to IO15 (if the voltage supply is 24V_EXT)
must not exceed the max. allowed current of 1 A. A self-resetting fuse limits
the current consumption.
Specification of terminal connections
▶ Conductor cross-section solid/stranded: 0.2 – 1.5 mm²
