Grenton BUS-201-D-01 TF-väylälähtömoduuli, 4-kanavainen rele, DIN-kiskokiinnitys

Unlike generic relay boards that need separate bus couplers or gateways, the Grenton BUS-201-D-01 is a native TF-Bus participant, delivering deterministic, low-latency switching for smart home and building automation. This output module brings four potential-free relay outputs directly to the field level, ready to control lighting, motors, valves, and other electrical loads. Housed in a compact 3-module DIN rail enclosure, it integrates seamlessly into standard distribution boards and draws power directly from the TF-Bus—no extra power supply needed.

Highlights

• Four independent relay outputs with potential-free contacts for versatile load control.
• Seamless integration with Grenton TF-Bus, enabling fast and deterministic command execution.
• Compact DIN rail housing (3 modules) for easy installation in standard distribution boards.
• LED indicators for each output and bus status, simplifying diagnostics and commissioning.
• Low power consumption, suitable for always-on smart home applications.

In daily use

The BUS-201-D-01 serves as the bridge between the Grenton system and high-power field devices. Each relay can switch up to 5 A at 250 V AC or 30 V DC, covering most lighting and small motor loads. The module is powered directly from the TF-Bus, eliminating the need for an additional power supply. Its robust PC/ABS housing and wide operating temperature range ensure reliable performance in typical indoor environments. Installation is straightforward: snap the module onto a DIN rail, connect the bus and load wiring, and it's ready for configuration.
