Actuators may be connected in parallel. Power consumption and input impedance must be observed. Actuators may also be powered by 24 VDC. Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback. 16 Actuators are provided with a numbered screw terminal strip instead of a cable. Meets cULus requirements without the need of an electrical ground connection. ! WARNING! LIVE ELECTRICAL COMPONENTS! During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury. 24 VAC Transformer Line Volts 12316 (1) Common (2) + Hot (3) + Input On/Off (1) Common (2) + Hot (3) + Input Line Volts 12316 24 VAC Transformer Floating Point ComHot 2316 Blk (1) Common Red (2) + Hot Wht (3) Y Input Line Volts 24 VAC Transformer 1 Floating Point - Triac Source 216 Blk (1) Common Red (2) + Hot Wht (3) Y Input Line Volts 24 VAC Transformer ComHot 6 1 Floating Point - Triac Sink ARX24-3-T N4 Technical Data Sheet NEMA 4X, On/Off, Floating Point Control, Non-Spring Return, 24 V 800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEAN Date created, 04/03/2020 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
