Each user-configurable signal conditioning module offers 500V isolation from the system and from other channels. A wide variety of solid-state-relay (SSR) I/O modules are available to sense AC and DC signals and to switch AC and DC loads.

An on-board jumper (JP2) allows users to determine the status of the digital outputs in the event of the loss/recovery of external power. When enabled, the loss of external power disables module ­outputs until the application program writes new values to the data bus. When disabled, the loss of power has no effect on the state or continued control of the outputs. Additionally, on-board logic disables module outputs upon detection of a CPU reset.

* Opto-22® modules must be purchased separately. All sales are final.
