LOGIC CONTROL INPUT and OUTPUT (Each Output)
LOGIC IN is a rear-panel opto-isolated input that is activated at an input current greater than
approximately 1mA. User can set LOGIC IN (via the keyboard) to enable the output, disable the
output, or be ignored when it is activated.
LOGIC OUT is an isolated rear-panel open-collector output that will sink up to 2mA when
activated ('switch closure'); the maximum voltage that can be applied to LOGIC OUT is 30VDC.
User can set LOGIC OUT to be 'closed' or 'open' for output enabled or disabled, current limit
(CI mode), power limit (UNREG mode), or for any fault trip.
ANALOG REMOTE CONTROL and MONITORING (Each Output)
Quasi-analogue inputs and outputs to set voltage and current limit and to monitor actual output
voltage and current. The control inputs are read four times per second by the
A-D converter and the output is set according to the selected input scaling; similarly the monitor
outputs are updated four times per second with values representing the actual output voltage and
current. These signals each have a range of 0 to 10V or 0 to 5V with respect to the shared COM
return signal; the set range applies to all inputs and outputs.

LINK MODES
In addition to independent output operation, the instrument is capable of operating in a number of
different voltage tracking modes which can be activated from the LINK MENU. These modes
include Output 2 voltage (V2) tracking Output 1 voltage (V1) by any ratio in the range 5% to
2000%, V2 and I2 set to track V1 and I1 (1:1) with total V1 + V2 displayed (useful when Output 1
and Output 2 are series connected), V2 and I2 set to track V1 and I1 (1:1) with total I1 + I2
displayed (useful when Output 1 and Output 2 are parallel connected).
