CHAPTER 8:
8.1

General

Isolated Analog Programming (4-20mA option, PN: G+IS420), factory installed as an option, allows
operation of the
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.
