12 Digital input (90-140 VDC) Module-DI12H
Quick Information
12 unipolar optical isolated digital inputs for 90-125 VDC The module is arranged in two sections of 6 inputs. All inputs are 2 wire with separate common for each single input. Each input channel is isolated from each other and electronics.
A user programmable debounce filter, in 1 ms units, is provided for each digital input, to filter out noise or mechanical relay bounce. This could also be used in combination with software counters, in case a low frequency mechanical contact is used for counters.
Before using the LB2 Series I/O Modules, read the LB2 User manual. 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. The maximum number of I/O modules on one LB2 Bus is 60.
