Function Notes Pin
DC Outputs 1-16 Nominal 24 Vdc Outputs capable of sourcing up to
250 ma. 1-16
DC Inputs 1-8 Nominal 24 Vdc Inputs (Sink or Source) Inputs
1-8 23-30
Sink/Source select pin
for DC Inputs 1-8 To make DC Inputs 1-8 “sourcing” inputs (24 Vdc
applied to the DC Input turns the input “on”), con-
nect 24 Vdc Common to this pin. To make DC In-
puts 1-8 “sinking” inputs (24 Vdc Common
applied to the DC Input turns the input “on”), con-
nect 24 Vdc (nominal) to this pin. 21
DC Inputs 9-16 24 Vdc (nominal) Inputs (Sink or Source) 9-16. 37-44
Sink/Source select pin
for DC Inputs 9-16 To make DC Inputs 9-16 “sourcing” inputs (24
Vdc applied to the DC Input turns the input “on”),
connect 24 Vdc Common to this pin. To make DC
Inputs 9-16 “sinking” inputs (24 Vdc Common ap-
plied to the DC Input turns the input “on”), con-
nect 24 Vdc (nominal) to this pin. 35
24 Vdc Out 24 Vdc power (nominal) is routed from the 3-pin
Power connector to these pins. Connect the Sink/
Source select pin (described above) to this pin to
configure the associated Inputs as “sinking” in-
puts. 20, 34
24 Vdc Common 24 Vdc Common is routed from the 3-pin Power
connector to these pins. Connected the Sink/
Source select pin (described above) to this pin to
configure the associated Inputs as “sourcing” in-
puts. 22, 36
