Part description

Product description
The devices of the ACT20X-HDI-SDO-S family transmit digital signals galvanic isolated from potentially explosive atmospheres to non-hazardous or less hazardous areas.
For this purpose the input circuits are designed intrinsically safe. They can process NAMUR sensor signals according to EN 60947-5-6 or be connected to potential-free contacts (with or without resistor circuitry).
Single and dual channel versions are available with relay or transistor outputs.

Ex isolating switch amplifiers for Namur sensors
1-channel isolating switch amplifiers in 22.5 mm width with an external power supply,
to transmit and isolate Namur sensor signals from Ex zones 0,1,2 into the safe zone.
On the output side there is a potential-free relay contact with closing function and an alarm contact for
status/error messages.
The component can be configured using standard FDT/DTM software.
