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.
