AMETEK B CONTROLS 5200-HV4 Solid State Relay

The AMETEK B/W Controls 5200-HV4 Solid State Relay is a rugged, electrode-driven switch that enables level-control systems to turn pumps, valves, or other loads on or off based on a sensed liquid level in a tank or well. It operates from 115 or 230 VAC at 50/60 Hz and provides double-pole, double-throw load contacts plus a holding circuit contact, with a maximum load of 10 A at 120/240 VAC (28 VDC) and horsepower ratings of roughly 1/4 HP at 120 VAC and 1/3 HP at 240 VAC. The HV4 variant features a highly adjustable sense range via a variable R1 resistor, covering about 0.007 to 1.0 megohms to accommodate a wide range of electrode resistances and sensor configurations. This relay is designed for direct operation from submerged electrodes in industrial tanks or wells, delivering solid-state switching for common liquid-level applications without moving parts and enabling precise electrical discrimination of the sensor signal.
