Feature
Specification
24 V power supply IN
External supply 24 V DC (20.4 V … 28.8 V) via X01 connector.
Use a power supply with PELV (PELV= Protective Extra Low Voltage
according EN 61800-5-1), Class 2.
The 0 V of the power supply must be connected with low resistance to the
PE of the system.
Maximum current consumption of unswitched power supply 1L+
(supplies control unit, encoder and fan)
1.2 A
Maximum current consumption of switched power supply 2L+
(supplies the two digital outputs)
1 A
Maximum load of the X01 connector (due to daisy chaining)
8 A
The converter is fully protected against reverse voltage
24 V power supply OUT The converter is fully protected against short circuit
Digital inputs
6 programmable digital inputs; PNP, SIMATIC-compatible, low < 5 V, high
> 10 V, maximum input voltage 30 V
Pulse inputs
DI 1 (X07.2)
DI 3 (X08.2)
Maximum frequency 32 kHz
Digital outputs
2 programmable, 24 V DC / 0 A …0.5 A (resistive). The maximum current
output is 0.5 A in total when using both or a single digital output.
Update time of all DO: 2 ms
