The PC4304 is a microtran programmable circuit module manufactured by Rockwell Automation. It is a 4-channel, 16-bit size module with pulse width modulation, constant voltage transformer and logic circuits. The PC4304 is used for controlling and monitoring applications in industrial automation, data acquisition, pulse width modulation, and motion control applications. It is compatible with many different PLCs, motors, and drives and can be interconnected with other PC4304 modules or to other devices using CAN, Ethernet IP, Profibus, or Modbus RTU protocol. It features up to 16-bit/channel resolution and 4, 8, 16 or 32 pulse width modulation outputs, which can be connected to a motor or motor-controlled drive. The PC4304 also includes analogue inputs, relay, threaded terminal blocks and several configurable I/O options, enabling multiple configuration options.
