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.
