Genuine Durable Car Component SRI983-BIDLFDZN - High Quality

The SRI983-BIDLFDZN is a high-performance, single-acting analog electro-pneumatic positioner designed for precise control of pneumatic linear actuators. It accepts a standard 4–20 mA DC two-wire loop-powered input signal and operates on direct-action logic (increasing input increases output).
