GC-RB23

Description

GC-RB23 is a B-BC class BACnet LAN communication integration controller. It has router function. Operate independently. The GC-RB23 has two network communication abilities, For upper level, it can link to a 100 Bases-TX BACnet Ethernet with selectable either the BACnet Ethernet (ISO-8802-2) or the BACnet/IP communication method. For lower level, it can link to three network of BACnet MS/TP, each MS/TP network can link up to 32 controllers, its communication speed can reach 76,800 BPS.

The MS/TP RS-485 interface has 1000V electrical isolated protection. GC-RB23 has programmable function and standard BACnet object, such as schedule, calendar and the event enrollment...etc. GC-RB23 device in conformity with international BACnet network communication and fully compatible with any BACnet system.

Features
