Isolated Analog Control Option Overview
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.
Note
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.
