4 DI(180-280 VDC) 4 DO (0-300 VDC) Module-DM08H
Quick Information
Combined module with 4 x high voltage digital inputs and 4 x solid state relay outputs module, with functionality like Hot Swap and Fail -safe. 200 MHz CPU, an intelligent module that can make decisions 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 RTU32N & RTU32M series. The I/O modules are in two parts, the bottom part contains the backplane bus, and the top part contains the I/O board and logic. All LB2 I/O modules are hot plugs. LB2 I/O modules are all equipped with a 200 MHz processor to process I/O’s and handle filtering, de-bouncing, module clock, general module logics, etc.
Module firmware update is handled from the RTU level in Brodersen Worksuite. Use only genuine Brodersen bus cables for connection to Brodersen RTUs and extension of I/O module blocks. The connection cables for LB2 are specially made to handle the power requirements and shielding to run communication. The maximum overall length of the complete system is 20m. Each I/O module & Power supply module is calculated as 2cm. The cables are as the length indicates, e.g., UCC-610/100 count as 100 cm. The maximum possible system configuration is 60 I/O modules on one LB2 Bus.
