The Yokogawa UT152-AN/RET is a single-channel intrinsically safe (IS) isolator designed for installation in Yokogawa UTSX Series rail-mounted housings. It functions as a rectifier-type isolator with an additional retransmission output, providing both safety isolation and signal replication. The module accepts a 4-20 mA signal from a 2-wire transmitter in a hazardous area, supplies loop power to it, and outputs two isolated 4-20 mA signals: one for the control system and one for retransmission to secondary devices (e.g., recorders, displays). The "AN" suffix indicates compliance with specific safety standards (e.g., ATEX, IECEx), while "RET" denotes the retransmission output feature.
