DSA-PI(PD,II)  Power distribution or current input barrier

1 in 1 out, 1 in 2 out, 2 in 2 out. 0/4~20mA intrinsically safe input. Distribution voltage ≥16V (at 20mA). 0/4~20mA output. HART passed. Terminal supply or DIN rail power supply is available.

·   DSA-PI (PD,II)  It is suitable for connection to a transmitter or current source in a hazardous area on site, provides power distribution to the field transmitter, and accepts 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 safety zone control system or other instruments.

·   Input signal 4~20mA or 0~20mA.

·   Output signal 4~20mA or 0~20mA.

·   Support HART pass (optional)

·   Input and output channel types are 1 in 1 out, 1 in 2 out, 2 in 2 out.

·   This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.

·   Small plug-in structure. Universal base type terminal block, terminal function is fixed, wiring is standardized, M3 screw is fastened.
