Ocean Controls Modbus TCP I/O Module 8DO+4DI+3AI
Modbus RS-485, USB, and Ethernet I/O module. DIN rail mountable. 8 relays, 4 opto-isolated inputs, 3 analog inputs.
The KTA-324 is a Modbus Slave I/O module for interfacing to any PLC or PC using the Modbus (RTU and TCP/IP) protocol. It behaves as a Modbus Slave and Relays, Inputs and Outputs are controlled by writing to and reading from the Coils and Holding Registers. It can be used for many applications such as controlling lights and sprinkler systems, reading sensors and monitoring switches and other digital signals, or even for industrial control.
The module can connect to a standard RS-485 2-wire half duplex network, to a computer via USB, or over the Internet using Ethernet. When connected via USB, the module acts as a USB to RS-485 converter and multiple IO units (or other Modbus devices) can be connected to the RS-485 bus. USB drivers are available for Windows, Mac and Linux.
The user can save a set of output statuses to be loaded when the unit is powered up or reset. A watchdog timer can be configured to reset the unit after a user-definable number of seconds since the last communication from a Modbus master.
