The Yokogawa UT150-RR/RS is a single-channel alarm trip module designed for rail mounting in Yokogawa UTSX Series housings. It monitors 4-20 mA DC signals and provides two configurable alarm setpoints with relay outputs. The "/RS" suffix denotes its remote reset functionality, allowing alarm conditions to be reset either locally via a front button or remotely via a dry contact signal. The "RR" designation indicates operation with a 120 V AC, 60 Hz power supply, making it suitable for North American and other 120V AC markets.
