8 Remanence Relay (Change over SPDT) Module-DO08F
Quick Information
8 x relay output module with change over contact sets. with functionality like Hot Swap, Fail-safe with Force Low, Force High, Keep Last State, 200 MHz CPU, intelligent module that can make decision without the CPU card available. module variables ( Heartbeat, Temperature, Operating hours, Hours since restart, restart counter, serial number, input voltage…. and many more )
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 the 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
