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 ‘doubleup’ as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection. Modules with a comprehensive range of voltage ratings cover all process related signals such as RTDs, THCs, 4 to 20mA loops, telemetry outstations, shut-down systems and fire and gas detectors.
