7.2 ACT20X-HTI-SAO (Temperature/mA Converter)
7.2.1 Description
The modules of the ACT20X-HTI-SAO family transmit analog signals galvanic isolated from hazardous areas
to the safe area. The input circuits are designed intrinsically safe.
The ACT20X-HTI-SAO converts and isolates current and temperature sensor signals (mA, RTD and TC).
The two-channel version ACT20X-2HTI-2SAO can be used as a signal splitter for mA signals.
For the higher accuracy of thermo couple signals, the use of special cold junction terminals ACT20X-CJC-
HTI-S recommended:
1160640000 ACT20X-CJC-HTI-S PRT 11 (1-channel)
1160650000 ACT20X-CJC-HTI-S PRT 21 (2-channel)
