Grenton ModBus Master Integration Module, DIN Rail Mounting, Ethernet

The Grenton ModBus Master Integration Module (model 22521) is a professional DIN rail-mounted interface designed to seamlessly integrate Modbus RTU and Modbus TCP devices into the Grenton Smart Home System. Acting as a Modbus Master, it enables centralized control and monitoring of industrial and building automation equipment such as HVAC, lighting, energy meters, and more. With dual Ethernet and RS-485 connectivity, this module ensures reliable communication and easy configuration via Grenton Object Manager software.

Advantages

This module simplifies the integration of third-party Modbus devices into a Grenton smart home ecosystem, eliminating the need for additional gateways. Its compact DIN rail form factor (2 modules wide) saves space in electrical cabinets. The dual-interface design (Ethernet + RS-485) provides flexibility for various network topologies, while the low power consumption (max 2W) ensures energy efficiency. Configuration is straightforward through the Grenton Object Manager, making it accessible for both installers and advanced users.
