Installation & Setup Guide
I/O Configuration Type “M” ( Double Ended I/O )
The double ended I/O configuration of the control provides additional flexibility in connecting to
external devices. These I/O points allow the user to separate the control voltages for each I/O point.
Meaning, there is no common tie between each point as with the single ended I/O scheme. No power
is required to be brought into the control. Pins 34-37 are provided for the optional internal +24V
supply should the user want the power supply integrated into the control.
Double Ended I/O Pinout
The Single Ended I/O offers eight outputs which are rated at 24VDC for up to 1-amp loads and eight
inputs rated for 24VDC.
