The TT230 and TT330 series of space-saving, 2 or 4-wire transmitters and isolators are offered for a range of inputs with sink/source 4-20mA output compatibility. Using isolation, these transmitters protect from surges, noise, and ground loop errors.
The BusWorks XT series of Ethernet I/O modules support Modbus TCP/IP, Ethernet/IP, Profinet and i2o peer-to-peer communication protocols. They monitor and/or control up to 16 discrete devices per unit with any mix of inputs and outputs supported.
989EN-4C16: Commercial (no counters)
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. Industrial-grade units have eight 32-bit pulse counters with timers, alarms, and non-volatile memory for metering, totalizing, and low-frequency periodic measurement. Outputs control solid-state switching of lamps, horns, and other devices.
