These modules provide an isolated Ethernet interface for any input/output mix of up to 16 discrete signals. Inputs sense the status of dry contacts, switches, power supplies, and DC logic. Industrial-grade units have eight 32-bit counters with timers, alarms, and non-volatile memory for metering, totalizing, and low-frequency periodic measurement. The outputs control solid-state switching of lamps, horns, and other devices.
16 solid-state discrete I/O channels (any mix of inputs/outputs); 3-way isolation and surge suppression; Web browser configuration; Automatic MDI/MDI-X negotiation; Inputs accept 2- or 3-wire sensors and active logic switches (dry contacts, proximity, namur, 5-28V DC logic); Inputs detect level and change of state; 8 configurable counter/timers -32-bit up/down pulse/event counters (with non-volatile memory) -16-bit periodic timers for "last pulse" -Momentary/latch alarms (each counter); Programmable de-bounce (0-65 seconds with 1mS resolution); Programmable power-up conditions; Over-temperature, over-current, and over-voltage output protection; Ability to "read-back" output states; Watchdog timer output configurable for fail-safe or hold-last-value operation; Self-test and auto-copy functions
