MicroSmart Pentra RS232 Communication Module

• Up to 5 modules can be added to a MicroSmart Pentra Slim CPU

• Allows MicroSmart Pentra Slim to communicate with up to 7

serial devices

• Up to 3 modules can be added to a MicroSmart Pentra All-In-One

CPU allowing communication with up to 5 serial devices.

• Communicate with HMIs, variable frequency drives (VFD),

barcode readers, RFID equipment, printers, additional CPUs,

displays, PCs, web servers, etc.

• Screw termination for easy wiring

• The communication circuit is isolated from the internal circuit

allowing for high noise resistance

• Maximum baud rate: 38.4 kbps
