496 - Masoneilan 496 Series Non-Contact Opto-Electronic Positioner Transmitter, 4-20mA Output, NEMA 4X/IP66/67 Enclosure

496

496 is a non-contact opto-electronic positioner transmitter designed for rotary and reciprocating valves, providing a 4-20mA analog output signal proportional to valve position. The device features a robust NEMA 4X (IP66/67) enclosure for reliable operation in demanding environments. The 496 Series transmitter is engineered for accurate valve position feedback and includes built-in lightning protection rated at 1500W (10/1000µs). It supports both direct and alternative power supplies, with options for intrinsic safety and polarity inversion protection. The wiring connection is made directly to mechanical switches, and the transmitter is suitable for integration with a variety of valve actuation systems.
