Available in either 4, 6, 10, 22 or 32 channelsDesigned for ease of installation in your dust collector systemFor installations requiring fewer channels than available on the board, a shorting plug (DCT604 & DCT610) or dip switches (DCT622 & DCT632) allows selection of the last used channelTime-on and time-off settings are selected using two potentiometersHigh-limit and low-limit control inputs are provided for use with on-demand systems. Units can also work in continuous clean modeFor safety, the control circuitry including the control inputs and the last channel jumper is isolated from the power line
