Product Overview

XpertIO DC-28P is a simple and stable monitoring module that supports independent communication, high performance, and standard open protocols, which can be satisfied with general or special applications.Supports BACnet IP/MSTP and ModbusTCP/RTU mainstream communication protocols.


The DC-28P, which can be connected to the local area network (LAN) through the field bus, can remotely control and manage the remote controlled equipment to meet the general or special applications.

The DC-28P is suitable for use both as a simple input/output monitoring module and as a controller for controlled devices that require specific logic independent monitoring internally.

DDC-28P also has the Modbus bridge function, which transfers a Modbus RTU packet from the device to Modbus TCP communication in the way of a bridge.
