Description
The Schneider Electric (Barber Colman) AK-42309-500 is a direct-acting positive positioning relay designed to provide precise, repeatable positioning of pneumatic actuators in commercial HVAC and building automation systems. Supplied with mounting linkage for straightforward field installation, this relay is factory set with a 5 lb (5#) span, ensuring accurate signal-to-stroke response right out of the box.
Positive positioning relays are essential in pneumatic control systems where accurate actuator positioning is critical — eliminating the effects of friction, hysteresis, and varying supply pressures to deliver consistent, reliable control of dampers, valves, and other pneumatically operated devices.
