The romod series from romutec offers a comprehensive range of modular components for building automation. These modules are specifically designed to handle versatile control and monitoring tasks in combination with Modbus RTU devices. From digital and analog inputs to relay outputs and specialized 3-point controls, the series covers a wide array of applications.

Features

The romod series is characterized by its modular design and ease of integration. Each module in the series features an independent RS485 interface, eliminating the need for additional gateways. The autobauding function automatically detects the baud rate, simplifying installation and commissioning.

Key features include:

• Diverse I/O support: Digital and analog signals, counter functionality, and relay control.
• Modular expansion: Easily scalable through the combination of various modules.
• Local operation: Each module enables manual control, priority override, and status display.

Technical Data

The romod series includes modules such as:

• 16DI: Digital input module for monitoring up to 16 signals.
• 8DO and 8DO-R: Digital output modules with MOSFET or relay outputs.
• 4DIO-R: Combination of digital inputs and outputs.
• 8AI and 8AO: Modules for processing analog signals such as temperature and voltage sensors.
• 4DI2DO-R-3P: Module with specialized 3-point relay outputs for blind and damper controls.

The series supports all common Modbus commands and is compatible with a variety of automation systems. Its high protection class and robust design ensure a long lifespan, even in demanding environments.
