1.1 Module Introduction

CAR series module using RS485 communication port,Based on the standard Modbus protocol, with extensive use of significance. Including the extension of the model input and output modules, analog input module, analog output module, temperature acquisition module. EX Series PLC, MD series of text display, and other related equipment to support Modbus protocol has been widely used in temperature, flow, level, pressure and other process control systems.

1.2 Module size:
