Acromag Ethernet IO

The 900EN series is a rugged, high-performance line of Ethernet distributed I/O modules. Modules feature universal input/output ranges and an intelligent microcontroller to provide extreme flexibility and powerful remote monitoring and control capabilities. Select from a variety of analog and discrete I/O models to meet your application requirements.

Each inch-wide module has a direct network interface, processes I/O signals on up to twelve channels, and handles power conversion. This space-saving approach is very cost-effective for systems that need to add I/O channels at an existing control site or network to new remote sites. By comparison, many “block I/O” devices would require a large, expensive processor block, an I/O rack, individual plug-in I/O terminal blocks, and a special system power supply.

The I/O modules are easily configured using your standard web browser. Each I/O module has embedded web pages to help you set up and control the unit. These web pages guide you through the steps to configure network settings, calibrate the module, and test the operation.

Sophisticated 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.
