MTL SD series surge protector

　　Thinner design - easy to install, automatically grounded through DIN rail

　　Thinner design - saves space inside the cabinet

　　Multi level hybrid protection circuit - capable of withstanding surge currents up to 10KA

　　Automatic Recovery - No Maintenance Required

　　Complete range of types - suitable for most process input/output applications

　　High bandwidth, low impedance, specially designed for RTD, PSTN, and three wire instrument circuits

　　The compact design of the SD series surge protection products can save more cabinet space and is widely suitable for various process control requirements. The internal reliable hybrid protection circuit, combined with the optional "circuit fuse protection" function, can provide better surge protection solutions for various process control system applications.

　　The thinner card slot design makes the entire module more compact, and more protectors can be installed in the same cabinet space without affecting usage and operation. Any two wire or three wire circuit can be fully protected by a separate module.

　　Design products that work under different voltage requirements for different applications, providing surge protection measures for RTD, THC, 4-20mA circuits, field stations, emergency shutdown systems, and fire and gas systems in control systems.

　　The optional "circuit disconnect" function allows customers to install, debug, and maintain without disconnecting the surge protector in the circuit, simply unplugging the fuse. The third terminal on each side of the protector allows users to safely disconnect the hazardous and safe sides of the cable.

　　Specially designed for three wire applications, SDRTD (for RTD) and SD32T3 (for 24V three wire circuits) can provide protection while ensuring lower impact on signal accuracy. For the protection of three wire sensors, SDxxR3 series products can be selected.

　　For certain communication circuits that require higher bandwidth response, the SDR series products can meet the needs of these high-speed communication systems. SDPSTN is suitable for protecting PSTN communication/modulation adapter circuits. For certain circuits with high operating voltages, 120V and/or 240V power supply circuit protection can be provided for field instruments. When the current is below 3A, the SD series also has corresponding products.

　　Simple manual operation can embed SD into DIN rail and automatically complete reliable grounding connection through DIN rail. One guide rail can accommodate multiple SD series surge protectors. If installed incorrectly (not reliably connected to DIN), it is very easy to detect and can be reinstalled correctly. The standard T-shaped DIN rail is suitable for installing SD series products, and for special environmental requirements, special coating products can also be provided. Optional series installation accessories are also available.
