Remote Monitoring of Output Voltage and Current
Readback
Signals
The J2 connector on the rear panel provides access to calibrated readback signals for
remote monitoring of the output voltage and current. Use rear panel switches SW1-5
and SW1-6 to select either a 0-5 Vdc or a 0-10 Vdc range for the output. The
readback signal represents 0 to 100% of the power supply’s output.
See Table 4.2 for the required J2 connections and switch settings for remote
monitoring of readback signals with 0-5 Vdc or 0-10 Vdc outputs. Use shielded pair
wiring (20 to 24 AWG) and ground the shield to J2 connector terminal 1 or to the
chassis. See
Figure 4.3 and Figure 4.4 for sample configurations using remote
monitoring.
Table 4.2 Power Supply Settings for Remote Monitoring of Readback Signals
Note:Check the readback accuracy any time you reset the SW1 switch. Access offset
and range adjustment for the readback signals through the cover of the unit.
See
“Calibrating for Readback Accuracy” on page 80 .
