HUB_RTU

The HUB-RTU is a consolidation module that also serves as an installation aid, allowing you to quickly and easily connect multiple Modbus RTU devices to a gateway. It’s ideal when space is limited in the control cabinet and you need to install a large number of Modbus RTU devices.

Short on space in the control cabinet? Too many Modbus RTU devices and not enough interfaces on the IoT module? The HUB-RTU tidies up the cable clutter and connects up to 8 Modbus RTU devices to a single module or gateway. Clear architecture and functionality—great practical benefits.
