IN7004851K20000 – BACnet/IP & MS/TP Client to Modbus TCP/RTU Server gateway, 1200 points, DIN rail, 24 VDC, UL/BTL certified

IN7004851K20000 – industrial BACnet/IP & BACnet MS/TP Client to Modbus TCP/RTU Server gateway, supporting up to 1200 points, DIN rail mount, 24 VDC powered.

IN7004851K20000 is an advanced gateway from the Intesis IN700-485 series, designed to integrate BACnet/IP and BACnet MS/TP devices with systems using Modbus TCP or Modbus RTU. The device acts as a BACnet Client and simultaneously as a Modbus Server, making BACnet objects available to Modbus-based networks. With support for up to 1200 points, it is the ideal solution for medium to large building automation and industrial projects requiring reliable interoperability.

The gateway supports both BACnet/IP and BACnet MS/TP, as well as Modbus TCP and Modbus RTU simultaneously. With its integrated BACnet Explorer function, devices and objects can be automatically discovered on the network, greatly simplifying commissioning. Support for up to 6 simultaneous Modbus TCP clients ensures stable communication even in complex systems. Configuration and monitoring are carried out through the intuitive Intesis MAPS software, offering project templates, validation tools, and easy firmware updates.

The device is designed for DIN rail mounting and operates with 24 VDC ±10% or 24 VAC power supply. Its compact enclosure (90 × 88 × 58 mm) allows easy integration in control cabinets. Front panel indicators include LEDs for power, error, and communication status, as well as buttons for factory reset and sending BACnet I-Am messages. Two RS-485 ports provide flexibility for Modbus RTU and BACnet MS/TP networks, while the Ethernet port enables Modbus TCP and BACnet/IP communication. A USB mini-B port is available for configuration and firmware updates, and a USB host port can be used for logs, project files, and software upgrades.
