TP24/7
Safeguards 4 wire process transmitters against induced surges and transients from field cabling

 Specifi cally designed for Multivariable Transmitters and Level Transmitters
 Four wires protected, one pair at 12V to 24V and one pair at 7V (e.g. RS485)
 Easy and direct mounting - simply screws into spare conduit entry
 Intrinsically safe and fl ameproof to CENELEC standards
 FM for US and Canada and ATEX approved
