Remote Analog Operation
TM-XDOP-01XN 4–7
The analog setpoint and readback pins may be configured to work in either a 0–
5V range or 0–10V range.
The programming lines have their own isolated power source (10mA max), and
this power can be looped back to power the user lines, if required. Connect the
pins as shown in Table 4-3.
Remote Interlock Using a Contact Closure
The interlock input may be configured for use with an external voltage free
contact. Connect pins as shown:
Closing an external contact across the interlock pins B2/A4 will then disable the
unit. Opening the contact will enable the supply output.
