INBACPAN128O000 – Gateway for Panasonic VRF to BACnet IP/MS/TP Integration, 128 Indoor Units

INBACPAN128O000 – Panasonic VRF to BACnet IP/MS/TP Gateway for 128 Indoor Units

The newer version of this device is IN771AIR00LO000

The INBACPAN128O000 gateway enables seamless bidirectional integration of Panasonic ECOi and PACi air conditioning systems (including PAC and VRF lines) with BACnet IP and MS/TP networks. Designed for large-scale HVAC installations, it supports up to 128 indoor units and ensures reliable control and monitoring of all key AC functionalities via a standard building automation system (BMS), SCADA, or BACnet-compatible controller.

The device connects directly to an indoor unit and offers control over essential parameters like mode selection, fan speed, setpoint temperature, and additionally provides monitoring of system errors, alarms and internal variables. The setup is fast and straightforward: just wire the device to the indoor unit and configure the DIP switches—no additional software or power supply is required. A built-in web interface allows real-time access for status checks, IP configuration, and simple remote operation.

With support for both Ethernet-based BACnet/IP and serial-based BACnet MS/TP communication, this gateway ensures wide compatibility. Its compact design fits neatly onto a DIN rail or wall surface and provides plug-and-play integration into automation networks. The device also complies with major international certifications (CE, RoHS, EMC), and its extended operating temperature range (0°C to 70°C) makes it suitable for demanding environments.
