ABB SIGMA R1050 ANALOG INPUT MODULE

ABB SIGMA R1050 is a rack-mounted industrial analog input module for legacy ABB Sigma series distributed automation systems, widely used in marine engine room monitoring and land-based process control. This analog input module receives 4‑20mA field signals from pressure, temperature, level and flow transmitters, converts analog measuring signals into digital data and transmits to the main system controller. This analog input module supports multi-channel signal acquisition, with built-in signal filtering circuit to suppress electromagnetic interference in vibration-rich industrial and marine environments. This analog input module works on 24VDC system power supply and is installed inside instrument racks.

This unit is a vital legacy process automation spare part for factory and marine control cabinet overhaul. The legacy process automation spare part continuously collects machinery field measuring data for alarm monitoring and trend recording. The legacy process automation spare part supports parameter configuration for different sensor types and signal scaling. The legacy process automation spare part can replace faulty module to restore analog signal acquisition for process monitoring system.

It delivers reliable multi-channel field analog signal processing for industrial automation systems. The multi-channel field analog signal processing samples process measurement values continuously. The multi-channel field analog signal processing filters noise to guarantee stable measurement accuracy. The multi-channel field analog signal processing sends alarm signals to central workstation when process parameters exceed safe preset limits.

ABB Sigma R1050 belongs to discontinued Sigma series automation I/O modules, commonly deployed in water treatment, power plants and old marine engine monitoring cabinets.
