PR Electronics 5202 Pulse Isolator

Feature & Principle

It is PR electronics 5202 dual-channel pulse isolation safety barrier. It receives NAMUR proximity switch or dry contact pulse signal, realizes electrical isolation between field hazardous side and safe control side. It can detect cable break and short circuit fault, output relay or open collector signal to PLC. Different suffix versions support different power supply and output types, compact DIN rail installation, widely used in chemical explosion-proof zone speed, flow, position pulse signal transmission.
