Applications
The 420 Type-P was used in industrial process control systems, particularly in manufacturing and utility applications requiring proportional control. These controllers were commonly integrated into larger control systems and instrumentation racks for temperature, pressure, and flow regulation. Historical use spans utility automation, chemical processing, and industrial HVAC applications.
This Leeds & Northrup 420 Type-P process controller has been inspected and appears to be in good used condition overall. The aluminum housing shows general surface soiling and light wear consistent with industrial service, and the rating plate and front panel markings are legible. The four internal adjustment knobs (Proportional Gain, Rate Time, Repeats/Minute Reset, and Approach) are present and intact. The front panel percentage indicator strip and circular setpoint dial are visible and appear undamaged. The card-edge connector on the rear is present. This unit was previously labeled for an ETEC system application (Unit 2 ZIC-120 MFL Feed Valve) as seen on the front panel tags. It has not been powered or tested at our facility.
