together.
4.7 Discrete Output (DO) Modules
The five-channel Discrete Output (DO) module provides two-state
outputs to energize solid-state relays and power small electrical loads.
These are solid-state relays. A Discrete Output may be set to send a
pulse to a specified device. Discrete Outputs are high and low outputs
used to turn equipment on and off.
DO modules can be software-configured as latched, toggled,
momentary, or Timed Duration Outputs (TDO). The DO can be
