Inside Detector
The optocoupler transistor output is able to sink 10mA current in non-saturated
condition. Absolute maximum voltage is 24V. Do not apply a voltage with reversed
polarity.
Depending of the connection the trigger output can be active high or active low.
When “optocoupler collector connection” is used:
“Trigger Output Collector” is pulled up with a resistor (of 10k) and
“Trigger Output Emitter” is connected to ground
Then “Trigger out” is active low (= integration state of detector).
When “optocoupler emitter connection” is used:
“Trigger Output Collector” is connected to VCC (supply) and
“Trigger Output Emitter” is pulled down with a resistor (of 10k)
Then “Trigger out” is active high (= integration state of detector).
In this document the state of “Trigger Out” is “active” (integrating) or “not active”
(reading/reset of pixels).
Passive trigger output levels: 0…[email protected]
Active trigger output levels:
Saturation voltage: <0.4V@ <10mA
Maximum allowed current: 10mA
