I. Product Overview

51204162-125 (MU-TAIY52) is a 16-channel analog input field terminal component of Honeywell UCN (Universal Control Network), serving as a signal interface unit between APM/HPM controllers and field instruments, responsible for collecting, conditioning, isolating 4-20mA standard analog signals and transmitting them to the control system. It is widely used in signal acquisition in the fields of petroleum, chemical engineering, and power control.

II. Core Specification Parameters

V. Installation and Application Key Points

Standard DCS cabinet mounting rail installation, supports vertical / horizontal installation

Analog signal lines use shielded twisted pair cables, laid separately away from power cables

Single-ended reliable grounding of the shield layer to avoid circulating interference Strictly distinguish between positive and negative signals and the common terminal connections

Application scenarios:

Signal acquisition of pressure transducer

Signal connection of temperature transducer (4-20mA)

Signal input of flow and level instruments

Signal acquisition of valve positioner feedback
