A wide variety of voltage interface capabilities. Isolated and non-isolated module types. Point-level output fault states. Choice of direct-connect or rack-optimized communications. Field-side diagnostics (on select modules). Most output modules have built-in surge suppression to reduce the effects of high-voltage transients. However, we recommend that you use an additional suppression device if an output is being used to control inductive devices, such as: relays, motor starters, solenoids, motors.
