Product Description

CompactLogix Modbus TCP Network Adapter C4374

Brief introduction

The C4374 supports the mounting of 32 IO modules, and the CPU and IO modules are designed separately, which can be freely combined according to the needs of the site, and can achieve lower cost requirements in the case of a large number of points. The module has 3*RJ45/1*RS485/1*CAN interfaces, supports Modbus RTU, Modbus TCP, EtherCAT, CANOpen protocol access, easy configuration, fast debugging.

-30°C~70°C wide temperature of the whole machine, it can cope with various industrial sites, EMC performance to meet IEC61131-2, IEC61000-4 standards. The expansion module is mainly divided into 6 categories, digital input module, digital output module, analog input module, analog output module, special module and hybrid IO module.
