BRIDGE

Series 100
BRG-N100
RS-485 Network Bridge with Configurable Display and Alarm Capability

The BRG-N100 functions as an analog input to RS-485 network bridge. It supports both BACnet MS/TP and Modbus RTU. In addition, it can bind to a remote BACnet object (AO, AI or AV) to read BACnet devices without a dedicated B.A.S. network.

  • Analog Input to RS-485 Bridge
  • Make any Sensor a Network Sensor
  • Accurate Voltage Measurement
  • Scalable Signal Conversion
  • Display Custom Units of Measure
  • RS-485 BACnet/Modbus Connection
  • Substitute BACnet AI for Analog Voltage
  • Alarm Capability
  • Dry Contact Relay
  • 1-year Warranty

Typical Applications

  • Analog Signal to RS-485 Network Bridge
  • Remote Display for RS-485 or Analog Signal Device
  • Low/High Setpoint Alarm

Benefits

  • Convert any Analog Output Sensor to an RS-485 Network Sensor
  • Display any BACnet MS/TP Device without a B.A.S. Network
  • Satisfy Alarming Requirements of Codes and Standards

Product Highlights

  • Stand-alone Bridge
  • Fixed or % Tolerance Alarming
  • Simple Pushbutton Interface
  • No Additional Devices Required for Setup

General

User Interface: 16-character LCD display and 4 button interface

Input

Type: Analog input (AI1)
Ranges:
Voltage: 0-10 VDC
Current: 4-20 mA (from 4 wire source, no excitation voltage)

B.A.S. Connectivity Options

BRG-N100 Bridge: One field selectable (BACnet MS/TP or Modbus RTU) and non-isolated RS-485 network connection for the scaled network value of AI1, including units of measure – A remote BACnet network object (AO, AI or AV) may be substituted for the physical analog input (AI1) in applications that require an RS-485 BACnet device be read without a B.A.S. network.
Note: this functionality is not available for Modbus devices. Provide individual 24 VAC transformers at each BRG-N100 bridge for applications requiring isolated RS-485.

Relay
