Details

DS-PI /PD/ II Power distribution or current input isolator

· 1 in 1 out, 1 in 2 out, 2 in 2 out. Distribution voltage ≥17V (at 20mA). 0/4~20mA input. 0/4~20mA output. HART passed. Terminal supply or DIN rail power supply is available.
· DS-PI (PD, II) is designed to be connected to a field transmitter or current source to provide power distribution to the field transmitter and to accept current signal input from the transmitter. Current source signal input can also be accepted separately. After isolation, interference suppression, etc., output standard current signals to the control system or other instruments.
· Output signal 4~20mA or 0~20mA.
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
