CHAPTER 8 ISOLATED ANALOG PROGRAMMING OPTION
8.1 INTRODUCTION
Isolated Analog Programming is an internal option card for analog programming of the Genesys
power supply series. The option is factory installed and cannot be obtained with GPIB (IEEE)
Interface. Output Voltage and Current Limit can be programmed and readback 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:
1. 0-5V/0-10V option (PN: IS510): Using 0-5V or 0-10V signals for programming and readback.
2. 4-20mA option (PN: IS420): Using current signals for programming and readback.

NOTE:
Use 100Kohm minimum input impedance for the monitoring circuits to minimize the readback error.
