The Model C111 is a DIN rail mount I/O module with four analog input channels and four discrete channels that can be used for either inputs or outputs. It may be configured for either Profibus or Modbus communications on its isolated RS-485 serial port. The C111’s comprehensive math, logic, control and diagnostic func-tions and highly configurable I/O make it an ideal choice as a stand alone controller, as remote I/O for Profibus and Modbus-based control systems or as an I/O interface for data acquisition systems.
