Non-isolated DI/O modules consist of a digital input/output PCB with
two 10-point terminal block assemblies for local termination. The DI/O
module also includes 14 configuration jumpers, an LED board with 16
status LEDs (one for each point), and a cover assembly. The DI/O
module connects with the backplane using a 36-pin gold-plated card-
edge connector.
Non-isolated DI/O modules contain field interface circuitry for up to 12
digital inputs and four digital outputs.

non-configurable externally powered DOs.
Using configuration jumpers W1 through W12, you can set each DI
individually to provide either a 2 mA or 60 uA source current. Table 3-2
details jumper settings.
