Genie Signal Electrical Details
•
Power Supply (pin 2) : +12V DC nominal.
Operating tol10% to –10%.
Over voltage and reverse voltage protection circuit built in. The protection circuit is reset by shutting down or
disconnecting the power supply.
•
The 12-pin Hirose male connector shell and cable shield should connect to the supply earth ground to improve
EMI shielding.
External Inputs
•
Opto-coupled (2V to 12V, 2mA minimum) with internal current limit.
•
RS422 or TTL signal type (see figures below).
•
24 Volt signals supported with additional external current limiting (see figure below).
•
Used as trigger or integration control.
•
External signal polarity selected via configuration parameter.
•
User programmable debounce time from 1 to 255µs.
•
See " Input Controls via Sapera LT or GigE Vision Compliant Applications " on page 52 .
The opto-coupler is typically a Fairchild HMHA281 with the following characteristics.
