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: 2000 to 10000 (5% to 25% LEL), 20000 ppm max. alarm |
|
Warning Concentation (PPM)
PPM (1000 to 20000, less than or equal to alarm, 0=no Warning State)
Output Signal Type and Action
0-3 VDC (500mV offset, 250 steps of 11.73mV each, one step per 200 ppm)
Voltage encoded state (0.5V normal, 1.25V warning, 2.00V alarm, 0V/2.75V error)
TTL (Max 0.2V "low", min. 2V "high", select type below)
Open drain (2A/60V, select type below)
If TTL/Open Drain output, signal is triggered by:
Warning State and/or
Alarm State
Error Handling
If sensor fails or operating temperature is out of bounds, signal this by:
Using Error state
Converting Error state to Alarm state (fail safe)
Input Power Supply
3 VDC (regulated +/- 3%)
5 - 24 VDC
Interface Harness
Include Molex 15cm color-coded wire interface harness
AC/DC Power Suppy
None
Include 110VAC-to-9VDC power supply (2m cord)

1: ProtiSen™ product family identifier
2: Target Gas. X = H(ydrogen)
3: Alarm Level. nnn = concentration code. (code = Alarm PPM / 200 PPM)
Alarm Action. x: A = trigger nothing. C = trigger TTL/Open Drain
4: Warning Level. nnn = concentration code. (code = Warning PPM / 200 PPM)
Warning Action. x: A = trigger nothing. B = trigger TTL/Open Drain
5: Output Signal Type.
1 = TTL/Open Drain norm-hi/on, auto reset.
2 = TTL/Open Drain norm-low/off, auto reset.
3 = TTL/Open Drain norm-hi/on, latching.
4 = TTL/Open Drain norm-low/off, latching.
5 = 0-3VDC proportional (analog).
6 = Voltage-encoded state (step analog).
6: Binary signal type. 0 = n/a. 1 = TTL. 2 = Open drain.
7: Error Handling. 1 = Error state. 2 = Errors trigger alarm.
8: Input Power Supply Range. 1 = 3VDC. 2 = 5-24VDC
9: Interface harness. 0 = none. 1 = Harness included.
10: AC/DC power supply. 0 = none. 1 = 110VAC-to-9VDC adapter.
