Part description

Description of article
Hexagon screwdriver with cross-grip and pilot tip, size 4 
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.

Long specification

Ex isolating switch amplifiers for Namur sensors, 2 channels
2-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 per channel with opening function
and a common alarm contact ("a" contact) for status/error messages.
The component can be configured using standard FDT/DTM software.
