8 Channel PT100/1000 AI08T

Quick Information

The AI08T module is 8-channel RTD module that measure temperature for PT100 and PT1000 sensors. The PT100 and PT1000 mode can be chosen by jumper on the module. The module can be used with both 3 and 2 wire RTD sensor. Super fast with 200 Mhz processor and 16 Bit AD

The AI08T module is an 8-channel RTD module that measures temperature for PT100 and PT1000 sensors. The PT100 and PT1000 mode can be chosen by jumper on the module. The module can be used with both 3 and 2 wire RTD sensors. The Brodersen LB2 modules can be used with the RTU32N and RTU32M series products. 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 I/O modules are hot pluggable and equipped with a 200 MHz processor to handle filtering, de-bouncing and logic processing of I/O.

Module firmware updates are managed by the RTU using Brodersen Worksuite. Use only genuine Brodersen bus cables for connection to Brodersen RTUs and extension of I/O module blocks. The LB2 connection cables are made to handle the power and shielding requirements of the LB2 bus communications. The maximum overall length of complete system is 30m. Each I/O module & Power supply module is calculated as 2cm. The cables are as their length indicates, e.g., UCC-610/100 cable is 100 cm. Before using the LB2 Series I/O Modules, read the LB2 User manual. The maximum number of I/O modules on one LB2 Bus is 60.
