Product Description

PR electronics 2231D Programmable f/I – f/f converter

The PR electronics 2231D is a versatile and programmable frequency converter designed for industrial applications. It accepts a wide range of frequency input signals, including NAMUR sensors, NPN/PNP sensors, tacho generators, and TTL encoders. The device converts these inputs into standard analog current/voltage signals or frequency/pulse outputs. Featuring high galvanic isolation between input, output, and supply, the 2231D ensures signal integrity and protects connected equipment. Configuration is easily managed via the PReset software, allowing users to tailor the device to specific application needs. Its compact design allows for easy DIN rail mounting.
