Appendix | Industrial Process Interface for thermoIMAGER TIM 40 (Optional)
thermoMETER TIM 8 / thermoIMAGER TIM 40
The industrial process interface provides the following inputs and outputs:
Designation
Description
max. range
1)
/ status
A IN 1 / 2
Analog input 1 and 2
0 - 10 V
2)
D IN 1
Digital input
(Low-active = 0…0.6 V)
24 V
AO 1 / 2 / 3
Analog output 1, 2 and 3
Alarm output 1, 2 and 3
0/4 - 20 mA
0/4 - 20 mA
DO 1 / 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. 5 V <
(1.5 + working resistance * 0.021) < 24 V. Working resistance = Load bzw. Measuring resistance;
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.
i
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.
