16 Analog in, 4 Digital in, 2 Relay, 2 Analog out

Intech 2400-A16 I/O multiplexer

The Intech 2400-A16 is a capable Input/Output multiplexer, compatible with the ezeio Controller. The A16 has 16 isolated analog inputs capable of connecting directly to RTD or Thermocouple devices, as well as current loops or voltage sources. Each input can be individually configured.

The two on-board relays can be expanded to up to 32 additional relays using the 2400-R2 relay expansion device.

The A16 communicates with the ezeio Controller via Modbus. The ezeio makes the data from all the inputs available remotely via the web securely.
