Number of the digital inputs
Maximum 4
�-"10.10-Digital I/Os" on page 93
Type
Type 1 according to IEC 61131-2, current consuming
Wire lengths
In the control cabinet: The voltage drop must be taken into consideration
when choosing the wire cross section; there are
no other practical limitations.
Field wiring: All relevant national regulations as well as the requirements
of IEC 61131-3 must be fulfilled.
Load rated voltage L2+
24 V DC (safety extra-low voltage SELV according to DIN EN 60950-1)
Reverse polarity protection
Digital inputs are protected against reverse polarity
Potential isolation
Achieved with optocouplers
Status display
One status LED per I/O
�-"10.10.1-Display of the Operational State" on page 93
Alarms
Can be implemented in the application program
Input delay (hardware)
From 0 to 1: max. 100 µs
From 1 to 0: max. 100 µs
Sampling time
The sampling time corresponds to the task interval of the application
program that reads the input.
�-"10.10.4.2-Pulse Detection and Disturbance Suppression" on
page 97
The task interval (and thereby the sampling time of the inputs) is set
in the task configuration of the MACS development environment.
Input capacitance
Max. 10 nF
Power consumption for the internal control circuit (L2+/M2)
≤ 100 mA
