9. ISOLATED ANALOG PROGRAMMING OPTION
9.1. Introduction
Isolated Analog Programming is an internal option card for Remote Analog programming of
the Genesys
TM
power supply series. The option is factory installed and cannot be obtained
with IEMD, LAN or USB Interfaces. Output Voltage and Current Limit can be programmed
and read back through optically isolated signals which are isolated from all other ground
references in the power supply.
There are two types of Isolated Analog programming cards:
a) 0-5V/0-10V option (P/N: IS510): Using 0-5V or 0-10V signals for programming and
readback.
b) 4-20mA option (P/N: IS420): Using current signals for programming and readback.
