Alarms and Bridges

GA Series

Remote Display, Alarms and Network Bridges

The GA Series offers versatile solutions for managing and monitoring analog and network signals with advanced display and alarm functionality.

The GA-100 converts analog signals into visible alarms with LED indicators and contact closure, making it ideal for sensors requiring a binary alarm output. With no setup required, it supports 0-10 VDC or 4-20 mA inputs, activating alarms when signals exceed preset thresholds.

The GA-200 expands functionality by acting as a display, alarm, and analog-to-network bridge. It converts analog sensors to BACnet MS/TP or Modbus RTU, while also displaying outputs on a 16-character LCD with customizable units. Built-in alarms support high, low, or high/low setpoints with user-defined tolerances and delays. The GA-200 simplifies sensor integration into BAS networks and allows any analog sensor to function as a network sensor.

Both models feature reliable alarm activation with LED indicators, contact closure relays, and straightforward operation for seamless implementation in any system.
