SST Series
4-20mA Loop Surge Protection Device
Transient Voltage Surge Suppression for discrete signaling 4-20mA protocols. Units provide protection against Transient Voltage that exceeds the nominal signaling voltage. Each line is protected against surge current impulses up to 10kA.
The SST Series is configured to work in series with the measurement/control lines being protected, diverting harmful transient energies while maintaining a tight clamp at the peak voltage. SST Signaling units protect 1 circuit consisting of 2 wires (1 pair) plus ground.
Units are designed to operate in a wide temperature range and are ideal for the protection of 4-20mA current loop transducers, and similar instrument/control applications.
Consult the factory with any special package and circuit performance requirements.
