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.
