The industrial process interface provides the following inputs and outputs:
Name Description max range 1) / status
A IN 1 / 2 Analog input 1 and 2 0-10 V 2)
D IN 1 Digital input
(active-
low = 0…0,6 V)
24 V
AO1 / 2 / 3 Analog output 1, 2 and 3
Alarm output 1, 2 and 3 0/4-20 mA
DO1 / 2/ 3 Relay output 1, 2 and 3 3) open/ closed (red LED on) / 0...30 V, 400 mA
FS Fail-safe relay open/ closed (green LED on)/ 0...30 V, 400 mA
1)
depending on supply voltage; for 0-20 mA on the AO the PIF has to be powered with min. 5V < (1.5 + working resistance * 0.021) <
24 V; Example: R
Load
= 500 ohm
→ U
min
= 1.5 + 500 * 0.021 = 12 V, R
Load
= 100 ohm
→ U
min
= 1.5 + 100 * 0.021 = 3.6 V
→ min. 5 V
2)
the AI is designed for max. 24 V, the voltage level above 10 V is not interpreted
3)
active if AO1, 2 or 3 is/ are programmed as alarm output
The alarm output can be configured as a threshold between 0-4 mA for no alarm and between
10-20 mA as alarm . For values outside the respective range, the relay does not switch on the
DO.
