Most Adcon RTU's require voltage input signals.
Most industrial installations supply mA-signals.
Therefore: A502!
The Adcon A502 is a state-of-the-art 4-20 mA Interface. It is designed to operate in existing facilities that are already equipped with sensors or data loggers as well as in new installations and enables continuous and accurate monitoring of important remote facilities and measurement points. There is no more need for time consuming and inconvenient visits for on-site data reading. An A502 can convert up to three 4-20 mA signals into voltage signals. An A723 addIT can operate up to 2 converters (=6mA values) , an A733 addWAVE up to 4 (=12 mA values). Conversion of mA signals into the respective unit is done by
device-specific drivers in the Adcon software.
The A502 interface comes in a robust IP 65/67 housing allowing for operation even in harsh environments. The 4-20 mA loops are galvanically isolated from the Adcon radio station and are either powered by an external power supply or directly by the attached sensors. If using self-supplying sensors the minimal loop voltage required is 6,5 Volts.
