R. STAHL 9002/10-187-020-001 Intrinsic Safety Barrier

Description:

The R. STAHL 9002/10-187-020-001 Safety Barrier is used to provide intrinsic safety between hazardous and safe areas by limiting electrical energy transmitted to field devices in explosion-hazardous environments. Commonly installed in process control systems, oil and gas facilities, chemical plants, pharmaceutical manufacturing, and industrial automation systems utilizing intrinsically safe instrumentation. Maintenance technicians and system integrators use this safety barrier for equipment repair, retrofit, expansion, and replacement to maintain certified explosion protection and reliable signal transmission.

Applications:

The R. STAHL 9002/10-187-020-001 is a dual-channel INTRINSPAK safety barrier designed for the intrinsically safe operation of field devices such as load cells, strain gauges (DMS), sensors, HART transmitters, solenoid valves, and potential-free contacts. It provides energy limitation for hazardous-area circuits while maintaining accurate signal transfer to the control system. Its compact DIN-rail design and standardized fuse system make it suitable for industrial process automation, instrumentation panels, and explosion-protected installations.
