ABB 3BSE036456R1 AI825 Analog Input Module

Core Performance & Industrial Application

The ABB 3BSE036456R1 is the AI825 four-channel analog input module of S800 I/O series for ABB System 800xA DCS.

Each channel adopts independent galvanic isolation design to collect bipolar current and voltage field signals.

It supports multiple signal types including -20~+20mA, 4~20mA, -10~+10V and 0~10V.

It has built-in channel fault diagnosis function to detect open circuit and abnormal signal status.

It needs to cooperate with TU8xx series terminal unit to complete field wiring connection.

It supports hot swap replacement without affecting the operation of other modules on the station.

It is widely used for pressure, flow and level signal acquisition in process control system.
