A common retrofit situation: the BMS is running, but a new pump’s fault contact, a few temperature sensors or a damper command need to be added. FiO-40 was designed for exactly this.
Why it is easy
- Nothing is programmed on FiO-40. The address at which each channel appears in the BMS is fixed and listed in its documentation; the integrator defines that list straight into the BMS.
- It connects over Modbus (Ethernet or RS-485) or BACnet (IP or MS/TP); you choose which from the web interface.
- Channel settings are made from the web interface or the phone app.
What you can add
- 16 digital inputs: fault and run contacts, meter pulses
- 8 universal inputs: temperature, humidity, pressure and similar sensors
- 8 relay outputs: pumps, fans, contactors
- 8 flexible outputs: proportional control of valve and damper actuators
Safety
If the BMS link drops, FiO-40 outputs can go to safe values you set for each channel. We explain this in “What do outputs do when power returns or the network drops?”.
