Current Loop Surge Suppressor One Wire

One Wire 4 to 20 mA
Current Loop Surge Protector


Type: TSP-WG4-20MA-xxxV-01 (Unipolar)
Type: TSP-WG4-20MA-xxxV-03 (Bipolar)


Where: xxx = Compliance Voltage

Features:

Application: Transient surge protectors provide common and differential mode protection for toll booths, drawbridges, street light controllers and railroad crossing gates/signals. Electronic equipment is extremely susceptible to transient voltages and surge currents due to its relatively fragile semiconductor construction. A surge protector is a cost effective method of ensuring that equipment will have maximum life.

Function: The module has a PROTECTED side which is connected to the transducer output or to the data acquisition system input and a LINE side which is connected to the transmission wire. The EARTH connection of the modules must be terminated to earth by low impedance heavy gauge wire.

Description:
The transient surge protector features a three stage protection mechanism which provides over-voltage and surge current protection for 1 wire +/- 4 to 20 mA current loops. Internally, the module has 100% redundancy to safeguard the system and prevent nuisance failures. This series of modules is for systems using a separate power supply for the transducer and the data acquisition system.

Technical Specifications: All specifications typical at nominal input voltage and 25°C unless otherwise specified.
