Hi, Dear! Welcome to our online store...
XSA-SPI /SPD/ SII power distribution or current input barrier (compliant with SIL functional safety)
· Functional safety and reliability are certified by SIL. 1 in 1 out, 1 in 2 out, 2 in 2 out. 0/4~20mA intrinsically safe input. The output signal is 0/4~20mA and supports HART pass. Terminal supply or DIN rail power supply is available.
· XSA-SPI (SPD, SII) is designed to be connected to a transmitter or current source in a hazardous area of the field, to provide power 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 safety zone control system or other instruments.
· SIL functional safety complies with the IEC61508 standard.
· Input signal 4~20mA or 0~20mA; output signal 4~20mA or 0~20mA.
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
