The Johnson Controls MS-FEC1611-0 controller is a 10-point type of BACnet FEC or Field Equipment Controller from the Metasys system series. It is designed for efficient and versatile control applications in building HVAC systems. It operates with a supply voltage rating of 24 Volts AC (with a voltage range of 20 Volts AC minimum to 30 Volts AC maximum) and 50/60 Hertz of frequency. It consumes 14 VA of maximum power. The MS-FEC1611-0 FEC is equipped with a robust H8SX/166xR Renesas microcontroller processor that offers reliable and precise processing capabilities. Addressing the controller for BACnet MS/TP communication is easily managed through its DIP switch settings, with valid field controller device addresses ranging from 4 to 127. The BACnet MS/TP communication option employs an RS-485 connection for seamless data exchange. The MS-FEC1611-0 is equipped with various inputs and outputs, including 2 universal inputs, 2 binary inputs, 3 binary outputs, and 4 configurable outputs. The universal inputs can be defined as 0-10 Volts DC, 4-20 mA, 0-600k ohm, or binary dry contact inputs, while the binary inputs can be defined as dry contact maintained inputs or pulse counter/accumulator mode. The binary outputs are defined as 24 Volts AC Triac outputs, with the option of selectable internal or external source power. The configurable outputs are defined as 0-10 Volts DC or 24 Volts AC Triac BO, providing flexible control options. The analog input resolution is 16-bit resolution, enabling precise measurements. The analog output resolution is also 16-bit resolution, with an accuracy of +/-200 mV in 0-10 Volts DC applications. The controller can be mounted horizontally on a single 35 mm DIN rail or securely screw-mounted on a flat surface using three integral mounting clips. The termination is through an SA Bus, providing convenient connectivity. The compact dimensions of the MS-FEC1611-0 controller measure 150 x 164 x 53 mm (5-7/8 x 6-7/16 x 2-1/8 in.), including the terminals and mounting clips, and it weighs 0.4 kg (0.9 lb).
