These modules provide an isolated Ethernet interface for any input/output mix of up to 16 discrete signals. Inputs sense status of dry contacts, switches, power supplies, and DC logic. Outputs control solid-state switching of lamps, horns, and other devices.
Industrial-grade units have eight 32-bit pulse counters with timers, alarms, and non-volatile memory for metering, totalizing, and low-frequency periodic measurement.
