Contact Closure Input Connections
Contact inputs are typically connected to switches or mechanical relay contacts. Five inputs are available
with each input requiring two conductors. Connect the normally open contact across the top and bottom.
If using a solid state switch as the input device, observe polarity of the connection: (−) on bottom, and (+)
on top. Each input cable connection point is labeled next to the terminal block TB8 and TB9 as shown
below.
