S600 Instruction Manual
4.1.4 Digital Outputs (DIGOUT)
The S600 supports 12 digital output (DIGOUT) channels, which are
open collector type outputs. The maximum current rating is 100
mAmps at 24 Volts dc. Output frequencies up to 0.5 Hz are possible.
Carefully check the DC polarity using an external DC supply in series
with the load. When using inductive loads (such as relay coils), place a
diode across the load. Refer to Figures 4-11 and 4-12.
The DIGOUT channels use the connectors labeled SKT-B and SKT-C,
which are located on the backplate of the P144 board. Refer to Tables
4-6 and 4-7 for the DIGOUT pin connections.
