Frequently Asked Questions
What is the recommended total cable length for installation?
The total cable length should not exceed 500m. Use shielded twisted pair leads (AWG28 or greater).
Where can this controller NOT be used?
Do not use it in places subject to icing, condensation, dust, corrosive gas, intense temperature changes, high voltage sources, or near carrying large currents.
How do I calculate the required load capacity for relays?
The output relay life is greatly affected by opening/closing capacity and conditions, so operate within specified electrical lifespan cycles.
What are the necessary terminal connections for communication?
If linking multiple units (1:N connection), up to 32 devices can be connected using the RS-485 interface. Only ends of the transmission path need a terminator.
