Overview

The RKI AirLink T3A is an explosion proof fixed gas detector with a wireless radio. It runs on 12 to 35 VDC and also has 4-20 mA and RS-485 Modbus outputs as standard, with electrochemical, infrared or catalytic bead sensors.

  • Wireless 900 MHz or 2.4 GHz radio plus 4-20 mA (3-wire) and RS-485 Modbus outputs
  • Electrochemical, infrared or catalytic bead sensor for LEL, CO, H2S, O2, CO2 and toxic gases
  • Wire powered (3-wire) 12 to 35 VDC, 2 W maximum
  • 2 configurable alarms with amber and red LEDs; 2 optional dry-contact relays
  • Sunlight readable 102 x 64 graphic LCD with white LED backlight
  • Magnetic switches for non-intrusive calibration, settings and diagnostics
  • CQPSUS explosion / flame proof Class I Div 1 and 2 Groups B C D (certification for select gases)
  • Works with AirLink 7010 / 7032 wireless controllers and RKI Beacon 110, 200, 410A, 800 and MC-6400 controllers

Built to order: choose the sensor (gas and range), the 900 MHz or 2.4 GHz radio, alarm relays and the optional remote sensor kit. Request a quote for pricing and availability.
