AL-2004 Analog Signal Isolation Transmitter Module

Feature & Principle

It adopts isolation transformer and optocoupler isolation design. It receives analog signal from field transmitters, after isolation and conversion, outputs standard analog signal to DCS or PLC. It effectively eliminates ground potential difference and common-mode interference. Zero and span can be calibrated on site. It has short-circuit protection and fault indication function, suitable for long-distance analog signal transmission.
