Safety Functions

Safety Functions	In a state with the SAFETY plug inserted to the SAFETY connector, trigger signals must not be input. In addition, the current output terminals are shorted in the DIA-708A so as not to flow the accidental current to the inflator.
Load Resistance Measurement	Apply weak current (Approx. 10 mA) to the inflator and measure the resistance. (*The measured resistance includes the cable resistance to the inflator. ) Measurement range: 0.0 to 10.0 Ω Resolution: 0.1 Ω Accuracy: Within ±0.3 Ω

Resistance measurement before the test	Just before conducting the test (when moving the SAFETY plug from the SAFETY connector to UNSAFETY connector), automatically measures the load resistance to detect errors such as cable broken. Only when the measured result is within the preset resistance range, the DIA-708A becomes waiting for trigger state to continue the test.
Resistance measurement after the test	After completing the ignition, automatically measures the load resistance for detecting the not ignited inflator. The measured resolution is displayed on the status LED on the top face.
CH Status	Displays the status of the DIA-708A with the LED on the front panel.
Buzzer	The built-in buzzer in DIS-7000A issues alarm in the following incident. ･ Recharging the capacitor for current output. ･ Detects errors when measuring the resistance. ･ Detects errors when checking the current output. ･ Built-in battery remaining capacity lowered.

Real time or 0.1 to 9999 ms Less than 100 ms: 0.1 ms step 100 ms or more, less than 1000 ms: 1 ms step 1000 ms or more, 9999 ms or less: 10 ms step

Accuracy

Less than 100 ms: Within ±20 μs 100 ms or more, less than 1000 ms: Within ±200 μs 1000 ms or more, 9999 ms or less: Within ±2.0 ms *The trigger output timing may delay due to level trigger operations.

1 (1B series, LEMO made)
Connects the conventional products via a cascade cable.

2 (2B series, LEMO made)
Connects a digital input cable or digital input junction box.

4 (1B series, LEMO made)

1 (D-sub connector, Japan Aviation Electronics Industry, Limited)
Connects a expansion module directly.

Connects the external LED unit (optional accessory) for the DIS-7000A.
The external LED unit indicates statuses (waiting for the trigger, recording, error).

Switch Trigger : Non-voltage contact input: 2 (Isolated input)
Cascade Trigger : Operated by cascade signals issued from the other units.
Software Trigger : Operated by commands issued from a control software.

Max. 48 (Including up to 4 master modules)
Each master module controls 15 expansion modules (max).

[Between Master Modules]
Through a cascade cable (Up to 10 m)

[Ring buffer mode]
Recognizes the switch trigger 1 or switch trigger 2 as the “Event point” and records data before and after the “Event point.”

Each channel has the following 3 formats.
･ Open collector (ON: Closed): Up to 24 V/30 mA
･ TTL (Positive logic 0 V → 5 V): Up to 15 mA
･ TTL (Negative logic 5 V → 0 V): Up to 15 mA

Real time or 0.1 to 9999 ms
Less than 100 ms: 0.1 ms step
100 ms or more, less than 1000 ms: 1 ms step
1000 ms or more, 9999 ms or less: 10 ms step

Less than 100 ms: Within ±20 μs
100 ms or more, less than 1000 ms: Within ±200 μs
1000 ms or more, 9999 ms or less: Within ±2.0 ms
