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.

Profibus DP IO

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

Each module provides a direct network interface for your I/O signals. Unlike “block I/O” devices that combine a large and expensive processor block with snap-on I/O terminal blocks, 900PB modules handle the network interface and I/O processing in a single, compact multi-channel module. This space-saving approach is very cost-effective for systems that need to add some I/O channels at an existing control site or network new, remote sites. To ensure unsurpassed performance, these I/O modules employ advanced microcontroller technology. Isolated input, output, power, and network circuits increase noise/transient immunity and prevent ground loops. Status LEDs provide diagnostic feedback.

Self-diagnostics and sophisticated watchdog timers simplify maintenance and troubleshooting. The watchdog timer invokes a failsafe condition if host communication is lost. For further security, a second watchdog monitors the microcontroller for failed operations or a “lock-up” condition and automatically resets the unit.

MODBUS RTU IO

Acromag’s BusWorks™ 900 Series I/O System is a collection of analog and discrete remote I/O modules with Modbus-RTU protocol network communication. BusWorks™ modules are ideal for a wide variety of distributed I/O applications including data acquisition & control, process monitoring, and test & measurement. Windows®-based configuration software simplifies module setup with easy selection of input/output ranges, alarm setpoints, and other operating parameters.

All 900MB I/O modules communicate over a high-speed RS-485 network supporting data transfer rates up to 115K baud. Analog input modules accept variable DC voltage, current, and thermocouple sensor signals and feature local limit alarm capabilities. Analog output modules provide DC voltage or current field control signals for local displays, recorders, variable frequency drives, valves, and other control equipment. Discrete I/O modules monitor and/or control the on/off status of industrial devices.
