ACT20X-HAI-SAO-S
Description:
- Ex-supply isolator for standard DC current signals, a two-channel, transparent HART supply isolator with an external power supply of 22.5 mm in width.
- It can be used to transmit and isolate standard signals ranging from 4 to 20 mA from Ex Zones 0, 1, and 2 to the safe zones.
- The input to the component is both active and passive.
- More than 15 VDC can be given to external sensors.
- There are two ways to run the 4...20 mA output circuit: passively and strongly.
- Through a relay contact, status and error messages can be obtained (NO).
- The component can be set up with the help of common FDT and DTM software.
- Extra housing for mounting on TS35 rails.
- Dimensions: screw connection; nominal cross-section: 2.5 mm2; L/W/H: 119.2/ 22.5/ 113.6.
- IP 20 is the protection level.
