Overview
The Elreha BMR-3001 is a high-performance relay output module designed for integration into ELREHA control systems. This industrial I/O module provides 12 isolated SPDT (single-pole double-throw) relay switching outputs on a compact DIN 35 mm rail-mount housing. The module communicates via RS-485 databus, enabling seamless integration with central control units and other networked I/O modules in refrigeration and HVAC applications.
Key Features
- 12 SPDT relay outputs with 8A switching capacity per channel
- DIN 35 mm rail-mount housing for compact panel integration
- RS-485 databus interface for networked control architecture
- Configurable databus address via on-module DIP switches
- LED status indicators for mains power and communication monitoring
- Pluggable terminal connections for field installation
