Remote Inhibit Input
Switch/Relay contact closure or direct short from this terminal to signal return
is required to Turn ON/OFF the power supply. Opening the contact would
shut down the output and would be latched after reclosing the contact, user
needs to turn ON the output.
Remote circuit must sink up to 10 mA from 5 VDC to enable.
TRIGGER IN
TTL compatible Input signal, active-high; provides external hardware
triggering of voltage, current ramp and sequencing functions.
Signal connects to Open-anode of opto-
isolator diode with internal 1kΩ
series resistor internal to power supply.
Voltage Rating: Maximum 24 V, Minimum -5V
Low state: 0.3 V max, High State 2.7 V min
TRIGGER OUT
Output signal, active-high; synchronization pulse of 10 ms when a change in
the output occurs.
Open collector transistor output, Collector is connected the 26-pin connector.
Emitter point of transistor is connected to common return pin of the interface
connector.
Voltage Rating: Maximum 30 V, Minimum 3V for Active High, Sink Current:
50mA
CC/CV status Output
Output signal, High state indicates Constant Current mode operation and
Low state indicates Constant Voltage mode operation.
Open collector transistor output, Collector is connected the 26-pin connector.
Emitter point of transistor is connected to common return pin of the interface
connector.
Voltage Rating: Maximum 30 V, Minimum 3V for Active High, Sink Current:
50mA
Output ON/OFF Status
Output signal, High state indicates Channel Output is ON and Low state
indicates Channel Output is OFF
Open collector transistor output, Collector is connected the 26-pin connector.
