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.

8.3 ISOLATED PROGRAMMING & MONITORING CONNECTOR
Refer to Table 8-1 for detailed description of the rear panel Isolated Programming & Monitoring
connector. To provide the lowest noise performance, it is recommended to use shielded-twisted
pair wiring.
Refer to Fig.8-1 for description of the connector.

CAUTION
Parallel Operation: Optional Isolated Analog IS510 / IS420 must be
installed in both the Master and Slave unit.
When the Isolated Analog Option is installed, do not apply any signals to the
non-isolated VPGM and IPGM (J1-9 and J1-10) pins. All other J1 features
may be used normally. Refer to Section 4.5 for a description of J1 features.
