Acromag 900EN series Ethernet I/O modules

The Acromag 900EN series is a rugged, high-performance line of networked I/O modules. These modules feature universal input/output ranges and an intelligent microcontroller to provide flexibility and powerful monitoring and control capabilities.

Users can select from a variety of analog and discrete I/O models to meet application requirements. Each inch-wide module has a direct network interface, processes I/O signals on up to 12 channels and handles power conversion. This space-saving approach is cost-effective for systems that need to add I/O channels at an existing control site or network to greenfield remote sites.

The I/O modules are easily configured using a standard web browser. Each module has embedded web pages to help in the set-up and to control the unit. Watchdog timers increase system reliability: all I/O modules have a watchdog that monitors the microcontroller for failed operations or a ‘lock-up’ condition and automatically resets the unit. If host communication is lost and a configurable watchdog timer expires, all analog and discrete outputs go to a fail-safe condition.

Acromag’s i2o technology provides an easier way to link inputs to outputs without a PLC, PC or master CPU. With i2o, many BusWorks 900EN I/O modules have the ability to operate like a long-distance transmitter. Users can convert sensor inputs at point A to process control signals at point B, or monitor a discrete device at one site by reproducing the discrete level with a relay output at another location.
