A553 Digital Port Extender
Please note: when connecting an A553 to I/O Port A, which also provides SDI-12 functionality through the digital pin, you will loose this functionality.
To operate the A553 your RTUs need to run firmware version 2.3.5 or higher. On the A850 Telemetry Gateway firmware 2.1.4 or higher is required.
The A553 Port Extender comes in a plastic box for DIN rail mounting. A cable to connect it to an ADCON RTU, featuring a 7-pin Binder connector, is included. It needs to be connected to a 24V power source, available within the electrical cabinet.
