PROTECTOR4 Four-Channel System Controller with Analog Inputs

Brand: GDS Corporation
Request Information
The GDS Corp PROTECTOR4 System Controller is designed to provide power for and monitor signals from up to four industry-standard 4-20 mA devices, including all GDS Corp gas monitors, sample draw monitors and process monitors.

The PROTECTOR4 has four 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 PROTECTOR4 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 PROTECTOR4 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 optional AC power supply, the Protector4 can supply up to 65 watts of external DC power for connected devices.
Features
  • Four 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 65 watts for external devices
  • Five pushbutton user interface
  • Four dry-contact alarm relays with 4A replaceable fuses
  • RS-485 serial MODBUS port
  • Relays support latching or non-latching mode
  • Operating temperature -40°C to +70°C
