Product Brief:

1172C29H01 is legacy analog output module manufactured by Emerson. It is key AO I/O card for distributed control system. It receives process control data issued by main controller, completes D/A conversion and outputs standard 4‑20mA analog signals to drive field regulating instruments and actuators. Built‑in signal isolation improves anti‑interference performance of field loop. On‑board LED provides visual diagnosis for power, channel working and fault state. This is EOL discontinued spare part,widely used for maintenance and renovation of legacy power plant DCS equipment. Please confirm hardware revision, backplane matching and firmware version before purchase. Strict ESD anti‑static protection shall be performed during installation.
