Dwyer DCT1006 is a dust collector timer controller with a temperature range of -40 to 140°F (-40 to 60°C). It has an accuracy of ±1.5% F.S. @ 73°F (22.8°C) and requires a power supply of 85 to 270 VAC, 50 or 60 Hz. It has an output signal of 4-20 mA and can support up to 255 channels using DCT1122 & DCT1110 channel expander boards. It has a storage temperature range of -40 to 176°F (-40 to 80°C), a power consumption of 5 W, and a pressure limit of 10 psi (68.95 kPa). It features two barbed connections for use with 1/8" (3.18 mm) or 3/16" (4.76 mm) I.D. tubing and a fuse of 3 A @ 250 VAC. The low voltage control circuitry is isolated from the line voltage for system safety. It offers off-time accuracy of ±1% of the value or ±50 msec, whichever is greater, and on-time accuracy of ±10 msec. The solenoid supply is 3A maximum per channel, and it has 6, 10, or 22 output channels. It has an off-time range of 1 second to 255 seconds in 1-second steps and an on-time range of 10 msec to 600 msec in 10-msec steps. It also has alarm contacts with a capacity of 1.5A inductive load or 3A resistive load @ 30 VAC or 40 VDC. The pressure ranges available are 10" w.c. or 20" w.c.
