Acromag, Inc. 1771-Y-U-1-M Lead Lag Module 4-20mA 250 Ohm 115V AC

Acromag 1771-Y-U-1-M Lead Lag Module is a signal-conditioning accessory that provides a controlled 4-20 mA output into a 250-ohm burden while powered from 115 V AC. It is designed to implement lead/lag dynamics in industrial control loops, helping stabilize and shape the response of current-loop signals used by sensors and actuators. The 4-20 mA current-loop interface and the 250-ohm burden are the principal electrical characteristics, dictating how the module drives downstream instrumentation and how voltage drops are developed across the load. With 115 V AC input power, the module operates on standard utility power in a wide range of industrial environments. This compact module offers a practical option for projects needing a dedicated lead/lag signal-conditioning stage within an automation or instrumentation installation that requires robust 4-20 mA signaling and reliable AC-powered operation. Common applications include process sensors, control valves, and other devices that rely on precise 4-20 mA signaling and where lead/lag compensation improves stability.
