ABB DSTA155P (DSTA 155P) 3BSE018323R1 THERMOCOUPLE CONNECTION UNIT PCB

ABB DSTA155P (Part No.3BSE018323R1) is a 14-channel thermocouple connection unit PCB for ABB Advant Master / MOD300 legacy DCS process control system. This thermocouple terminal interface board receives raw millivolt signals from 14 thermocouple temperature sensors, provides terminal wiring, surge protection and signal routing to DSTA156P analog input module. This connection unit supports multiple thermocouple types, galvanic isolation and EMI filtering, designed for industrial boiler, power plant and marine automation control cabinets.

This unit is a vital industrial DCS spare part for power plant and process facility cabinet overhaul. The DCS spare part collects temperature signals from thermocouple probes in pipelines and furnaces. The DCS spare part forwards conditioned thermocouple signals to DCS I/O modules for temperature calculation and trend recording. The DCS spare part can replace faulty PCB to restore multi-channel thermocouple temperature measurement.

It delivers reliable thermocouple signal routing & surge protection for distributed control systems. The thermocouple signal routing & surge protection handles weak millivolt temperature signals from field thermocouples. The thermocouple signal routing & surge protection suppresses electrical interference and protects backend DCS modules from transient voltage spikes. The thermocouple signal routing & surge protection provides continuous temperature monitoring for critical industrial process supervision.

DSTA155P PCB is rack-mounted inside ABB Advant Master DCS I/O rack. It is original ABB spare part for legacy process temperature monitoring system.
