Bailey/Babcock & Wilcox 1612K40G0001 Proportional Delay Unit

The Bailey 1612K40G0001 is a Proportional‑Delay Unit designed for Bailey NET‑90 / 7000‑series control racks. This analog module provides adjustable signal delay and ramping functions to ensure smooth transitions in process‑control loops. It prevents sudden step changes in actuator or control outputs by applying a controlled, adjustable ramp. These units are widely used in power‑generation, steam‑control, and industrial plant automation systems. Technical Specifications Model: 1612K40G0001 Proportional‑Delay Unit Function: Provides adjustable delay/ramp of control signals to ensure smooth, bumpless transfer in process loops Front Controls: RAMP TIME rotary adjustment (0–10 scale) Status Indicators: E1, E2, S0 LED indicators Signal Types (family‑specification): Bailey delay units typically accept 1–5 VDC or 4–20 mA control signals; output tracks input with controlled ramping behavior Ramp Range: Adjustable ramp time (0–5 minutes per 10% span change for Bailey proportional‑delay modules) Input Impedance: > 1 MΩ (family specification) Power Requirements: 24 VDC supplied by Bailey rack backplane (0.150 A typical for Bailey modules) Operating Temperature: 5 °C to 49 °C typical Bailey spec (0 °C to 60 °C extended) Mounting: Bailey Type 761‑series rack slot module (plug‑in card) Dimensions: Approx. 1.4 in × 7 in × 11.5 in (Bailey module frame standard) Application Areas: Boiler & furnace control, steam plants, industrial control loops, nuclear & conventional power generation Manufacturer: Bailey / Babcock & Wilcox, Wickliffe, Ohio Country of Manufacture: USA Please review pictures carefully and let us know if you have any questions!
