DS-WPD/WII two-wire loop power distribution isolator (two-wire loop current signal isolator)

 

· Two-wire system, 4~20mA isolated transmission. 1 in 1 out, 2 in 2 out. Small plug-in structure, universal base type terminal, standardized wiring, easy installation and convenient maintenance.
· DS-WPD 2-wire loop power distribution isolator or DS-WII current input isolator is a supplement to the four-wire equivalent meter. It features only two power supply lines and output current signal lines. The signal current is equal to the supply current, so the structure is simple, eliminating the need for 2 terminals and their wiring. In the case of small usage and low load, it is a viable option.
· Two-wire system, 4~20mA isolated transmission.
· Small plug-in structure, universal base type terminal, standardized wiring, easy installation and convenient maintenance.
