Part description

Product description
The ACT20X-HAI-SAO-S current supply isolator is a HART-protocol, transparent isolator for analogue DC current signals from Ex-zone 0. The input may also operate as an active current loop (the loop current provided by the device). The device provides an 4...20 mA current signal for the safe zone on the output side. The device is available as single-channel or dual-channel version.

Long specification

Ex supply isolator for standard DC current signals, 2-channel, HART transparent
2-channel supply isolator in 22.5 mm width with external power supply,
for transmitting and isolating 4...20 mA standard signals from Ex Zones 0,1,2 to the safe
zones. This component has active and passive inputs. External sensors can be supplied with
> 15 VDC. The 4...20 mA output circuit can be operated either passively or actively.
Status and error messages are available via a relay contact (NO).

The component can be configured using standard FDT/DTM software.
