8B I/O Modules

Acromag's BusWorks 900PB series is a high-performance line of network-ready analog and discrete I/O modules. They 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 I/O modules to meet your application requirements.

Each module provides a direct network interface for your I/O signals. Unlike "block I/O" devices that combine large, expensive processor blocks with snap-on I/O terminal blocks, 900PB modules handle the network interface and I/O processing in one, compact multi-channel module. This space-saving approach is very cost-effective for systems that need to add a small quantity of I/O channels at existing control sites or network to new remote sites.

To ensure high performance, modules feature an advanced microcontroller techology. On-board address switches and automatic baud rate detection (up to12 Mbps) simplify installation. Four-way isolation prevents ground loops and increases noise immunity. Indicator LEDs and self-diagnostics help to quickly catch problems.
