Ethernet I/O modules

Acromag has extended its BusWorks line of high-density Ethernet I/O modules with the 989EN for distributed I/O and SCADA applications with new isolated discrete I/O units that perform counter/timer functions. Available through Davis Controls, these space-saving, 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 have 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.
