1 RB24 Relay Box for 24 VDC motors part # 40995J Wire access ports Applications A Relay Box acts as an interface between FFI actuators and Direct Digital Control (DDC) systems such as Building Automation Systems (BAS), Heating/Ventilation/Air Conditioning Systems (HVAC), or Home Automation Systems. Use with Momentary Contact SPDT Switch, FFI part #SW5657-2W. A Relay Box allows independent control (open/close switching) of low voltage actuators connected to it. A Relay Box does not supply power; it receives power from an external, low voltage power supply. Dry contact connection by single pole single throw momentary switch and/or external control system. It converts the 2 wire reverse polarity switching needed for 24VDC motors (open/close) to a 3 wire open/closed type momentary switch (the most common type wall switch, which is also used with Building Management Systems). Controls multiple actuators with maximum current draw of VDC. FFI recommends do not exceed 80% of maximum capacity for relay boxes, therefore 16 amps. Specifications Power Input 24 VDC ± 10% Power Output ( Motor Group 1 ) VDC * Power Output ( Motor Group 2 ) VDC * Number of Output Leads 2 wires (polarity inversion) Safety Marks CE; not UL Recognized/labeled Operating Environment 14 to 140 F (-10 to 60 C) Max. Relative Humidity 60% Case Dimensions 154 x 113 x 75 mm (6 x 4.5 x 3 ) *Do not exceed 80% of maximum capacity, therefore 8 amps. Dimensions Recommendations for FFI Actuators & Controls: FFI only recommends UL compliant systems. FFI is a UL registered firm. Read FFI data sheets & installation guides before specifying project details. Project-specific needs vary depending on the number of actuators, electrical layouts, building management systems, distance between power supplies & actuators, and other details. Project specifications to comply with electric & building codes for wire gauge, wire connections and run distance, conduits, junction boxes must be arranged by the project electrical contractors. Distribute this guide to all project parties, including electrical contractors, architects, and building management personnel. 13-Jul page 1 of 6

2 Attention: Prior to installation it is essential to read these safety notices, warnings and installation instructions. SAFETY NOTICES (1) Read this guide carefully prior to installation. (2) After installation keep these instructions for later review. (3) Incorrect application or improper installation may result in system malfunction and/or damage to people or property. (4) To avoid electrocution when the RB24 s cover is removed, make sure that the RB24 is disconnected from the power circuit prior to making electrical connections at its internal terminals, or performing any other operation. (5) It is recommended that the RB24 be connected to a dedicated power circuit. (6) Installation must be done by licensed electricians and/or engineers. (7) Prior to installation make sure that... a) The existing electrical system complies with local building codes and regulations b) The power supply is compatible with the RB24 s specifications WARNINGS (1) Do not attempt to repair the Relay Box RB24. In case of malfunction, contact FFI Customer Service at or service@fenestration.net for instructions. For defect claims, FFI must inspect the component. The two-year warranty is provided by Ultraflex Control Systems (UCS). (2) RB24 is for indoor use only, and is not recommended for use in high humidity areas, such as greenhouses. (3) To be covered by the Warranty, UCS actuators must be used together with UCS-approved accessories (such as power supplies, control panels, control boxes, relay boxes, weather detectors, switches, etc.) MANUFACTURER S LIMITED WARRANTY Ultraflex Control Systems S.r.l. (UCS) products are guaranteed against defects in material and workmanship for a period of two years from the date of manufacture.
