CH2-OUTPUT-
ON-OFF
DIGITAL
INPUT
Remote-control input for output on/off with a logic signal: a logic-high, will
enable (turn-on) the output of the supply, and a logic-low signal disables
(turns off) the output.
Signal connects to Open-anode of opto-
isolator diode with 1kΩ series
resistor internal to power supply
Signal return: Pin 17
Voltage Rating: Maximum 24V, Minimum -5V
Low state 0.3V max, High State 2.7V min.
14
