The GDS-49 (Model 10-0248) two-wire toxic sensor transmitter provides a scaled 4-20mA current sink output suitable for long distance transmission to an appropriate receiver device such as a C1 or C2 Protector series controller or GASMAX transmitter.

Wide Variety of Available Sensors

The GDS-49 is compatible with all GDS Corp toxic sensors, including oxygen, hydrogen sulfide, chlorine, carbon monoxide and more. Built-in fault detection circuity constantly monitors the sensor for correct operation and sensors can easily be replaced in the field.

Rugged Detection

The GDS-49 is enclosed in a stainless steel housing with integrated flame arrestor and is CSA approved for all Class I, Division 1 and 2 hazardous environments. For certain highly reactive gases that are not compatible with stainless steel, the GDS-49 is also available in a configuration without a flame arrestor that can be installed as intrinsically safe (IS) with an approved IS barrier, A standard junction box is supplied with the GDS-49 for connection to field wiring.

Calibration Required

Initial factory adjustment is completed by installing a fixed gain resistor on the sensor. This resistor establishes the range and provides basic calibration. Since the GDS-49 electronics are completely sealed and potted for maximum protection, final calibration must be performed at the receiver device in order to meet the rated accuracy specifications and accomodate changes in sensor characteristics over time. GDS Corp. offers single, dual, four, eight and sixteen + channel controllers with compatible analog inputs suitable for final calibration, alarm, display and retransmission of monitored gas values.

Easy Installation

The GDS-49 includes an XP junction box and functions with loop voltages ranging from 10-30VDC; voltage drop across the GDS-49 is less than 9 volts. An integral “transient voltage suppressor” protects the GDS-49 against lightning and other electrical transients. Non-polarized wiring elimnates wiring errors.

FEATURES

  • Certified for Explosion Proof and Intrinsically Safe Installations
  • Compatible with all GDS Corp toxic sensors
  • Non-polarized loop powered interface eliminates wiring errors
  • Range and target gas configured by sensor module
  • Fault supervision circuitry detects failed or missing sensor & transmits warning (2mA)
  • Stainless steel case & potted electronics for high noise immunity in electrically noisy environments
  • Industry standard 4-20mA output signal for cable runs > 1000 ft
  • Available without flame arrestor for highly reactive gases
  • Easy interface to all GDS Corp 2, 4, 8 or 16+ channel controllers
  • Combine with GDS-55 Loop-Powered Alarm or GDS-54 Loop-Powered Indicator for more flexibility
  • Manufactured in USA
