4.2 Detailed I/O Specifications
Cable and connector specifications and connection examples for the Acquisition Trigger input
and the high-speed outputs are provided in the following sections.
4.2.1 Acquisition Trigger Input
Table 4-4: Acquisition Trigger Input Specifications
SPECIFICATION DESCRIPTION
ON 20 to 28V (24V nominal) Voltage
OFF 0 to 3V (12V nominal threshold)
ON 1.8 to 2.7mA
OFF <150 µ A
Current
Resistance ~10,000 Ohms
Delay 62 µ Sec nominal latency between leading edge of trigger and start of
acquisition. Input pulse should be minimum of 1ms wide.
The acquisition trigger input on the In-Sight 3400 sensor is opto-isolated. To trigger from an NPN
(pull-down) type photo-detector or PLC output, connect pin 2 (TRG+) to +24V and connect pin 3
(TRG-) to the output of the detector. When the output turns ON, it pulls TRG- down to 0V, turning
the opto-coupler ON.
To trigger from a PNP (pull-up) photo-detector or PLC output, connect pin 2 (TRG+) to the output
of the detector and connect pin 3 (TRG-) to 0V. When the output turns ON, it pulls TRG+ up to
24V, turning the opto-coupler ON.
