Product Code Numbers

MS-FAC4911-0 Advanced Application Field Equipment Controller for BACnet/SC or BACnet/IP Networks

Supply Voltage

24 VAC (nominal, 20 VAC minimum/30 VAC maximum), 50/60 Hz, power supply Class 2 (North America), Safety Extra-Low Voltage (SELV) (Europe)

Power Consumption

14 VA maximum

Note: The VA rating does not include any power supplied to the peripheral devices connected to binary outputs (BOs) or configurable outputs (COs), which can consume up to 12 VA for each BO or CO; for a possible total consumption of an additional 72 VA (maximum).

Power Source

+15 VDC power source terminals provide 100 mA total current. Quantity 3 located in Universal IN terminals - for active (3-wire) input devices.

Ambient Conditions

Operating: 0°C to 50°C (32°F to 122°F); 10% to 90% RH noncondensing

Storage: -40°C to 80°C (-40°F to 176°F); 5% to 95% RH noncondensing


32-Bit Renesas® microcontroller


16 MB flash memory and 8 MB RAM

Real-Time Clock Backup Power Supply

Super capacitor maintains power to the onboard real-time clock for a minimum of 72 hours when supply power to the controller is disconnected.
