21.3 Wiring for digital and analog inputs and outputs
Digital inputs can be wired to connector X2 and X5 and digital outputs can be
wired to connector X3 and X4.
The digital input, as defined in the EN 61131-2 type 1 with a 0.5 ms input
delay, is particularly suitable for connecting electronic switching devices,
sensors and switches, etc. It is used to convert a signal with two possible
states into a one-bit binary value.
The eight short-circuit proof digital outputs are provided on connectors X3
and X4 with +24 V/0.5 A.
On connector X1 the U+ and U- signals of the analog input can be wired to an
analog output signal. A differential measurement will be carried out without
connecting either input cable to ground (GND). The signal being measured
must fall within the input's permissible common mode range. Please refer to
 Table 7, page 144.
An additional I+/I- analog input can be wired on connector X1. A measuring
range of 4–20 mA with open wire monitoring is supported, as is a measuring
range of 0–20 mA without open wire monitoring.
The current input channel uses a differential voltage measurement at an
internal module resistor with a resistance of 50 .
It must be ensured that the input signal's voltage level falls within the
permissible common mode range.Please refer to  Table 8, page 145.
