Ocean Controls Modbus Mixed I/O Module 4DI+2DO+4AI+2AO
Four analog inputs(4-20mA, 12 bit), two analog outputs (4-20mA, 12 bit), four digital inputs with high speed counters, two relay outputs. USB and dual RS-485 ports; can be polled by multiple masters simultaneously.
The KTA-308 is a Modbus Slave device that allows control of a full mixture of I/O from a single Modbus Slave, negating the need to use multiple slave devices to meet your I/O needs. This single device features four analog inputs, two analog outputs, four digital inputs with high speed counters, and two relay outputs.
Dual RS-485 ports can be set up with their own Modbus address, baud rate, and parity and can be polled simultaneously by separate Modbus Masters. An additional USB port offers a third Modbus slave, useful to interface with a PC for configuration, logging, etc.
