PROTECTOR2 Dual Channel Alarm & Display Controller

Brand: GDS Corporation
Request Information
The GDS Corp PROTECTOR2 System Controller is designed to provide power for and monitor signals from one or two industry-standard 4-20 mA devices, including all GDS Corp gas monitors, sample draw monitors and process monitors.

The PROTECTOR2 has two ESD-protected analog inputs that operate over the full range of 4-20 mA devices.

The calibrated value of each input is shown on the graphical LCD screen along with alarm and status information.

The PROTECTOR2 includes four dry-contract alarm relays with user-adjustable alarm settings that may be set to either latching or non-latching operation.

When latched, the RESET / ESC button can be used to clear the latched alarm.

The PROTECTOR2 controller also includes an RS-485 serial MODBUS output that can allow remote PLCs or DCSs to monitor the input channels in real time.

When configured with an external AC power supply, the Protector2 can supply up to 25 watts of external DC power for connected devices.
Features
  • Two surge-protected 4-20 mA analog inputs
  • Three user-programmable alarm levels per channel
  • Power input +12 to +35 VDC or 110/220 VAC
  • Optional AC power supply provides up to 15 watts for external devices
  • Four pushbutton user interface
  • Four dry-contact alarm relays with 4A replaceable fuses
  • RS-485 serial MODBUS port
  • Wet-contact FAULT relay
  • Operating temperature -40°C to +70°C
