Aux I/O Port Pin Descriptions
Function Notes Pin
Encoder Input (A, A/, B,
B/, I, I/) Provides connections to an incremental encoder
having differential outputs. 1-6
DC Input 1-6 (DCIN1-
DCIN12) Provides connection to an input device (sink or
source). 32-37
DC Input 7-12 (DCIN1-
DCIN12) Provides connection to an input device (sink or
source). 39-44
DC Sink/Source A
(DCSSA) If this pin is connected to +24 Vdc, inputs 1-6 are
“sinking”. If this pin is connected to +24
Common, inputs 1-6 are “sourcing”. 31
DC Sink/Source B
(DCSSB) If this pin is connected to +24 Vdc, inputs
DCIN1-DCIN6 are “sinking”. If this pin is
connected to +24 Common, inputs DCIN7-
DCIN12 are “sourcing”. 38
Analog Input
(, ANLGIN-) +/- 10V 16-bit A/D input 13,14
Fast Inputs 1-5
(FASTIN1-5+,
FASTIN1-5-) Differential Fast Inputs for latching Encoder
position. 16, 17, 19,

24 Vdc out 24 Vdc output to be used to power connected
input and/or output devices. 8, 9
COM 24 Vdc Common used to provide the 24 Vdc
return path for sinking-type outputs. 10, 11
+5 Vdc Out +5 Vdc output to be used to power connected
encoder (150 ma maximum). 12
Shield Ground Provides a path for shield current through the
chassis to an external single point ground. 7, 15, 18,
