System Wiring
NOTE:
• On an AC controller (p/n 24B596), the J7 strip is line (input) voltage but the J6 strip is all 24VDC. On a DC con-
troller (p/n 24B591), the J6 and J7 terminals all carry the input voltage.
• SEN (x) jumper must be field installed.
Input Sensor Wiring:
DRY CONTACT SWITCH
SOURCE SWITCH - 2 or 3 Wire Type
SINK SWITCH - 2 or 3 Wire Type
NOTICE
Do not connect any of the SW+ (13,9,5,1) and SW-
(16,12,8,4) pins together, either directly or via a
switch closure. Doing so will create a short circuit
condition which will disable and potentially damage
the controller.
