Ultra-slim user-friendly devices for protecting electronic equipment and systems against surges on signal and I/O cabling
The SD Series is a range of surge protection devices combining unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional ‘loop disconnect’ facilities – features which make the series the ultimate surge protection solution for process equipment, I/O systems and communications networks. The exceptionally high packing densities are the consequence of an ultra slim ‘footprint’ for individual modules which can thus ‘double-up’ as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.
SDM - NEW MODULAR DEVICE
The SD Modular (SDM) combines the tried and tested protection of the well established SD series and adds modularity for ease of maintenance. The user can change the surge protection module without any interference with wiring. The SDM is backwards compatible with the SD series which means users can upgrade to the SDM when next carrying out maintenance upgrades. Available in all of the voltages, 7,16,32 & 55 with a current capacity of 700mA, the SDM represents a step forward in surge protection designed for process control applications.
SDX units, available in 7V, 16V, 32V and 55V versions (SD07X, SD16X, SD32X and SD55X respectively) are suitable for a wide range of applications including THCs, 4-20mA loops, shut-down systems and fire and gas detectors.
In addition to the many beneficial features offered by SDX devices, the SD variants fuse/disconnect package provides both fused protection against fault currents and a convenient method of isolating field circuitry from protected circuitry without needing additional disconnect terminals. Also provided is a third connection on the field and safe side of the protector in order to terminate screens safely to earth.
The SDR Series has been specially designed to meet the requirements for high speed data links with an extremely high bandwidth. SDR units are available in a range of voltage variants enabling a wide range of communication systems to be protected e.g. RS232, RS422, RS485, Bus powered systems etc. These devices are classed as simple apparatus and can therefore be used in hazardous areas without affecting the certification of the circuit.
SD32T3, SDRTD, SDR3
This series of SD surge protectors offer excellent levels of protection over all three wires in conjunction with minimal footprint requirements. This is the most compact 3-wire surge protector on the market.
SD32T3 is a three terminal SPD for 3-wire transmitters or sensors
SDRTD is designed specifically for Resistance Temperature Detectors
SDR3 is a three terminal SPD for high bandwidth applications
