Modbus TCP Remote I/O Communication Module RTU-EN01
Introduction
This operation manual only provides introductory information on electrical specification, installation and wiring.
RTU-EN01 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity,
electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key
or specific tools are required to open the enclosure) in case danger and damage on the device may occur. DO NOT
touch any terminal when the power is switched on.
Please read this manual carefully and follow the instructions to avoid damage on the product or harm on staff.
