Product Description

The barrier is designed for intrinsically safe transmission of the current control signal of actuators (I/P regulators, converters) from a safe area to a hazardous area using galvanic isolation.

Advantages

Allows transmission of HART signals.
The electronic circuits of the barriers are coated with varnish, which additionally protects the elements from external factors.
High conversion accuracy ±0.1%
These products are designed with functional safety in mind and are SIL2/SIL3 compliant.
Mounting on a standard 35mm wide DIN rail.
Easy installation/dismantling of the product.
The compact body allows for tighter installation.
Availability of power indicator.
