Dwyer DCT1110 Dust Collector Timer Controller is a reliable and accurate device with a temperature range of -40 to 140°F (-40 to 60°C) and an accuracy of ±1.5% F.S. @ 73°F (22.8°C). It operates on a power requirement of 85 to 270 VAC, 50 or 60 Hz, and has an output signal of 4-20 mA. With 6, 10 & 22 available channels, the controller can be expanded to support up to 255 channels using DCT1122 & DCT1110 channel expander boards. It is capable of off-times ranging from 1 to 255 seconds and on-times from 10 msec to 600 msec. Other features include pressure limits of 10 psi (68.95 kPa), two barbed connections for use with 1/8" (3.18 mm) or 3/16" (4.76 mm) I.D. tubing, and alarm contacts for 1.5A inductive load, 3A resistive load at 30 VAC or 40 VDC. Overall, the DCT1110 is a versatile and efficient dust collector timer controller.
