Hi, Dear! Welcome to our online store...
XSA-AO output safety barrier
· 1 in 1 out, 2 in 2 out. 0/4~20 mA intrinsically safe output. Support for HART adoption. Terminal supply or DIN rail power supply is available.
· XSA-AO is suitable for the connection between the control system output signal and the on-site intrinsically safe circuit. After isolation, the standard DC signal is output to intrinsically safe equipment (such as valve controller and electrical converter) in the hazardous area of the site.
· Input signal 4~20mA or 0~20mA. The output signal is 4~20mA or 0~20mA.
· Support for HART pass (optional).
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
