Automation Components, Inc.2305 Pleasant View Road | Middleton, WI 53562Phone: 1-888-967-5224 | Website: workaci.comPage 1Version: 3.0I0000600GENERAL INFORMATIONThe DMUX-4 is a selectable output controllerdesigned to expand the output capacity of anenergy management or process controller. TheDMUX-4S has up to four output relays. Common (C),Normally Open (NO), and Normally Closed (NC)connections are available for each output. Threeposition On/Off/Auto jumpers are standard andallow manual override at the DMUX-4. It converts arelay, transistor or Triac input signal to operate anappropriate relay output based on the duration ofthe signal. The relay output has an LED indicator fora visual verification of operation. There are also LEDindicators to show the presence of power to theDMUX-4 and the input pulse. This program offersdifferent modes of operation using the Solidyne™fast pulse input. This device is DIP switch selectablefor sequencing, or reverse sequencing or RooftopUnit 4 relay control.MOUNTING INSTRUCTIONSGround yourself to discharge static electricity before touching any electronic equipment, as somecomponents are static sensitive. The interface device can be mounted in any position. If circuitboard slides out of snap track, a non-conductive “stop” may be required. Use only fingers to removeboard from snap track. Slide out of snap track or push up against side of snap track and lift thatside of the circuit board to remove. Do not flex board or use tools.WIRING INSTRUCTIONSPRECAUTIONS• Remove power before wiring. Never connect or disconnect wiring with power applied.• When using a shielded cable, ground the shield only at the controller end. Grounding bothends can cause a ground loop.• It is recommended you use an isolated UL-listed class 2 transformer when powering the unitwith 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers mayresult in damage to any device powered by the shared transformer.• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, orother inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACIPart: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DCTransorb or diode, connects to the positive side of the power supply. Without these snubbers,coils produce very large voltage spikes when de-energizing that can cause malfunction ordestruction of electronic circuits.• All wiring must comply with all local and National Electric Codes.FIGURE 1: DIMENSIONSINTERFACE SERIESInstallation & Operation InstructionsDMUX-4Phone: 1-888-967-5224Website: workaci.com3.22"(81.78mm)4.82" (122.42mm) L10J10J9L9J1 J4J2 J3L2D2K2L1D1K1L4D4K4L3D3K3= AUTOA= OFF-= ONOPULSETRIAC NORMPWR+AC-DCIN+ -M 1POWERDE3O 2C2NC NO C1NONCAOAONONC C4 C3NC NOAOAO33.25"(82.55mm)4.69" (119.13mm) 0.70”(17.78mm) |
