  PART NUMBER GENERATOR

The most commonly selected options have been checked as defaults. If your preferred configuration is not selectable below, then please contact Neodym.

Target Gas

   Hydrogen (in air)   

Alarm Concentation (PPM)

   PPM     Recommended alarm concentrations:

  Hydrogen: 4000 to 10000 (10% to 25% LEL)  


Warning Level (Percent of Alarm Level)

   Percent (20 to 80, 0=no Warning Level)


Output Signal Type and Action

   0-3 VDC (60mV offset, 250 steps of 11.7mV each, one step per 100 ppm)
   TTL, Normally-High, Auto (self-clearing)
   TTL, Normally-Low, Auto (self-clearing)
   TTL, Normally-High, Latching (pushbutton/power-cycle reset)
   TTL, Normally-Low, Latching (pushbutton/power-cycle reset)
   4-20mA (10 to 750 Ohm load, range 0-20,000 ppm, 30VDC input supply maximum)

If TTL output, signal is triggered by: Warning State and/or Alarm State

Relay Type and Action

   None
   Normally-Closed, Auto (self-clearing)
   Normally-Open, Auto (self-clearing)
   Normally-Closed, Latching (pushbutton/power-cycle reset)
   Normally-Open, Latching (pushbutton/power-cycle reset)

If used, relay is triggered by: Warning State and/or Alarm State

Note: Normally-closed relay facilitates power failure detection.

Alarm Beeper

78 dB at 30 cm alarm beeper: None     include beeper

Error Handling

If sensor fails or operating temperature is out of bounds, signal this:

   Audio-visually only     by activating alarm devices(s) (fail safe)

Input Power Supply

   3 VDC (regulated)     6 - 40 VDC

Note: 30VDC maximum input supply for units with 4-20mA output signals

Packaging

none (circuit board only)
anodized aluminum enclosure (with flange)


Interface Harness

   Include Molex 15cm color-coded wire interface harness


AC/DC Power Suppy

   None
   Include 110VAC-to-9VDC power supply
   Include 110VAC-to-24VDC power supply

Note: Power supplies have 6 feet cord & Molex connector.
        24VDC supply recommended for 4-20mA output driving high resistance loop.
