Inch-wide Ethernet distributed I/O modules

The BusWorks line of high-density Ethernet I/O modules for distributed I/O and SCADA applications from Acromag now includes Model 989EN isolated discrete I/O that also performs counter/timer functions. The inch-wide modules provide an isolated Ethernet Modbus TCI/IP interface for any input/output mix of up to 16 discrete signals. Inputs sense the status of dry contacts, switches, power supplies, or DC logic. Industrial-grade units feature eight 32-bit pulse counters with timers, alarms, and non-volatile memory for metering, totalizing, and low-frequency periodic measurement functions. Outputs control solid-state switching of lamps, horns, and other devices. Commercial and industrial-grade models provide 16 individually configurable bi-directional I/O channels with a 0-28 V dc signal range. When configured as inputs, channels accept 2- or 3-wire sensors and active logic switches for use with dry contacts, proximity, namur, or 5-28 V dc logic. Outputs switch is 0.5 A/channel or 2 A total. www.acromag.com Acromag
