Introduction to LB2 I/O Series

The Brodersen LB2 I/O modules are designed for the RTU32M & RTU32N series. The I/O modules are in two parts, a bottom part containing the backplane bus, and a top part containing the I/O board and logic. All LB2 modules are hot swappable and equipped with a 200 MHz processor to process I/O, handle filtering, SOE, debounce, module clock and general module logic. Diagnostic variables are available for all LB2 I/O modules. Please see the module datasheets for full info.

Module firmware update is handled at the RTU level from the Brodersen WorkSuite.

Use only genuine Brodersen bus cables for connection to Brodersen RTUs and for extension of I/O module blocks. The connection cables for the LB2 backplane bus are designed to meet the power requirements and shielding to run high speed communications. The maximum overall length of a complete system is 30 meters. Each LB2 I/O module & power supply module is calculated as 2 cm. The cables are as the length indicates, e.g. UCC-610/1 count as 100 cm.

The maximum system configuration is 60 I/O modules on one LB2 Bus. If the configuration exceeds 60 I/O modules, an additional CPU is required.
