Property
Description
Consequence if the inputs are connected incor-
rectly
Defect possible
Type of input
Type 1
Arrangement and binary status of indicators
Switching status "high" is indicated by green LEDs on
the left side of the contact strip.
Consequence of removing or inserting an input
module when the voltage is live
Not permitted, defect possible
Specifications for signal evaluation
Digital inputs static, DI0 and DI1 can be operated as
interrupt inputs.
Table A.10 Digital inputs (current-consuming)
A.2.3
Digital outputs for direct voltage (current-supplying)
Property
Description
Protection class
Short circuit proof
Output short circuit proof: replace/reset the safety
device
Short circuit scan: defective output is checked every 3
s to see whether the short circuit is still present.
Existence of common potentials between the
channels
Reference potential: common GND for all digital out-
puts
Number and type of outputs
14 semiconductor outputs, not isolated
Properties of the protective circuit installed in the
output circuits against voltage peak values when
switching off inductive loads
Limitation to max. -62 V (U
Group
= -65 V)
Max. inductive load rating per channel: 1 J at 0.2 Hz
Consequence if the outputs are connected incor-
rectly
Defect possible; return feeding to other group sup-
plies possible
Tapping points of the indicators within the channel LED on the load side
Reaction of the output to malfunctions
In the event of controller failure: RESTART
Working method
Non-storing
Consequence of multiple overloads on multi-
channel modules
Defect possible, since not overload-proof

A.2.4
Analogue inputs
Property
Description
Input impedance in the signal range
<200 Ω
Measurement error at the input (at T=25°C, tem-
perature coefficient)
+/- 0.01 % of the full scale value
Greatest error across the full temperature range
+/- 20 ppm of the full scale value
Data format delivered to the application program
Binary
