TCA-AO output barrier

·   1 in 1 out, 2 in 2 out. 0/4~20 mA intrinsically safe output. The output load resistance is 0~550Ω. Support for HART adoption. Terminal supply or DIN rail power supply is available.

·    TCA-AO is suitable for the connection between the control system output signal and the intrinsically safe circuit. After isolation, it outputs standard DC signal to intrinsic safety equipment (such as valve controller and electric 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.
