CT-5321 Modbus Serial Port Module 1 Module Description The Modbus serial port module supports 1 channel RS485/RS232 /RS422 (optional), supports Modbus RTU/ASCII protocol, and supports master, slave and free transparent transmission mode. The serial Module CT-5321 could be applied with the adapter modules, so it could convert Modbus into other protocols such as Modbus TCP, Profinet, EtherCAT, EtherNet/IP, etc. When the module is used, serial port parameters and Modbus instructions should be configured in IO Config software. Devices with RS485/RS232/RS422 interface, which support modbus-RTU /ASCII, could be applied with CT-5321 to realize interconnection with upper PLC or upper computers. CT-5321 could be applied with devices such as: PLC, DCS, remote IO, VFD, motor start protection device, intelligent high and low voltage electrical apparatus, power measurement device, intelligent field measurement equipment and instruments, etc. 2 Technical Parameters General parameters Power: Max.500mA@5.0Vdc Isolation: I/O to internal bus: opto-couple isolation (3KVrms) Field Power: Nominal:24Vdc, Range:19.2～28.8VDC I/O Wiring：Max.1.5mm²(AWG 16) Mounting Type: 35mmDIN-Rail Size: 115*14*75mm Weight: 65g Environment Specification Operational Temperature: -40~85℃ Operational Humidity: 5%~95% RH(No Condensation) Protection Class: IP20 Serial Port Parameters M/S/F: Channel Number 1Channel M/S/F: Interface RS485/RS232/RS422 M/S: Protocol Modbus RTU/ASCII - Note: M represents the valid parameters of master mode, S represents the valid parameters of slave mode, and F represents the valid parameters of free transparent transmission mode.
