Product Code Numbers

MS-FAC2611 Field Application Controller

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 for FAC 2611 only

Note: 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 84 VA (maximum).

Ambient Conditions

Operating: 0°C to 50°C (3°F2 to 122°F); 10% to 90% RH noncondensing

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

Controller Addressing for BACnet MS/TP

DIP switch set; valid controller device addresses 4–127 (Device addresses 0–3 and 128–255 are reserved and not valid controller addresses.)

Controller Addressing for N2

DIP switch set; valid control device addresses 1-254

Communications Bus

RS-485: selectable BACnet MS/TP or N2

3-wire FC Bus between the supervisory controller and field controllers

4-wire SA Bus between field controller, network sensors and other sensor/actuator devices, includes a lead to source 15 VDC supply power (from field controller) to bus devices.


H8SX/166xR Renesas® 32-bit microcontroller


4 MB Flash Memory and 1 MB Random Access Memory (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.

4 - Configurable Outputs: Defined as 0-10 VDC or 24 VAC Triac BO

2 - Analog Outputs: Defined as 0–10 VDC or 4–20 mA

Analog Input/Analog Output Resolution and Accuracy

Input: 16-bit resolution

Output: 16-bit resolution, +/- 200 mV accuracy in 0-10 VDC applications


Input/Output: Fixed Screw Terminal Blocks

SA/FC Bus and Supply Power: 4-Wire and 3-Wire Pluggable Screw Terminal Blocks

SA/FC Bus Port: RJ-12 6-Pin Modular Jacks


Horizontal on single 35 mm DIN rail mount (preferred), or screw mount on flat surface with three integral mounting clips on controller


Enclosure material: ABS and polycarbonate UL94 5VB; Self-extinguishing, Plenum Rated

Protection Class: IP20 (IEC529)

Dimensions (Height x Width x Depth)

150 mm x 190 mm x 53 mm (5-7/8 in. x 7-1/2 in. x 2-1/8 in.) including terminals and mounting clips
Note: Mounting space requires an additional 50 mm (2 in.) space on top, bottom and front face of controller for easy cover removal, ventilation and wire terminations.
