Isolated Analog Control Option Overview 
 
The Isolated Analog Connectors are 8 pin 
sockets that are optically isolated from the 
power supply, allowing inputs with ground 
references that differ to the power supply. The 
isolated options include either an isolated 
voltage (0~5V/0~10V) interface or an isolated 
current (4~20mA) interface. Only one type of 
isolated interface can be used at any one time. 
The pins used determine what remote control 
mode is used. 
The GPIB Option (PSU-GPIB), the isolated voltage 
option (PSU-ISO-V) and the isolated current 
option (PSU-ISO-I) all use the same option slot, 
meaning that only one of the three options can be 
used at any one time.
