Process Control

The Series SVT Solenoid Valve Enclosure with Timer is a compact, reliable and economic package designed for small to medium filtration systems. It combines a timer board and solenoid valve enclosure into one package, eliminating the need for separate enclosures and wiring. The SVT is available with 2, 4 or 6 valves. For larger systems expansion modules can be daisy chained to the SVT for a maximum of 60 outputs. The universal power supply accepts 90-240 VAC at either 50 or 60 Hz for both domestic and international requirements. On-Demand Cleaning or Down Time Cleaning functions can be selected with a simple dip-switch. Time-On and Time-Off settings are selected using two potentiometers.

Applications:

• Dust collection
• Pneumatic conveying
• Industrial vacuums

The Series DCT600 Timer Controller is a timing system for pulse-jet type dust collectors or pneumatic conveying systems in either continuous or on-demand cleaning applications. It provides either 4, 6, 10, 22 or 32 channels. The DCT600 was designed for ease of installation in your dust collector system. For 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 channel. Time-on and time-off settings are selected using two potentiometers. High-limit and low-limit control inputs are provided for use with on-demand systems. Units can also work in continuous clean mode. The new enhanced board circuitry of the DCT600 synchronizes the on-time pulse to the power line to achieve a pulse stability of ±1 msec. For safety, the control circuitry including the control inputs and the last channel jumper is isolated from the power line.

Ideal for pneumatic conveying systems, the Series DCT500A Low Cost Timer Controller is designed to provide continuous or on-demand cleaning for receivers and pulse jet systems. Available in either 4, 6 or 10 channels, each unit is the same size, minimizing enclosure space and reducing overall system installation cost.
The DCT500A is simple and easy to use. Time-On and Time-Off settings are selected using two potentiometers. High Limit and Low Limit control inputs are provided for use with on demand systems. The new enhanced board circuitry of the DCT500A synchronizes the on-time pulse to the power line to achieve a pulse stability of ±1 msec.
For added safety, the control circuitry including the control inputs are isolated from the line voltage.

To meet your system requirements, an optional weatherproof enclosure is available. For on demand systems, a Dwyer Series A3000 Photohelic® gage or Series 1800 Pressure Switch may be used with the DCT500A.

Applications:

• Dust collection
• Pneumatic conveying
• Cement batch plants

The SERIES DCT1000 Dust Collector Timer Controller simplifies on-demand cleaning requirements by eliminating the need for external devices such as pressure switches, relays, and timers. The modular design allows for use as a continuous cleaning control or on-demand cleaning control using the optional plug-in pressure module. The DCT1000 is the same size for 6, 10, and 22 channels, allowing one board size to be the standard on one enclosure.

Applications:

• Dust collection
• Pneumatic conveying

Features:

• Universal power requirements for both domestic and overseas use
• Standard mounting holes to other dust collector controllers for use in existing installations
• Able to automatically detect any channel expander connected

The Series PMT2 Particulate Transmitter is designed to measure particulate emission levels from dust collector discharge. Using DC coupled electrostatic induction sensing technology, the transmitter monitors a pA current that is generated as particulate passes near the probe; a 4 to 20 mA signal will vary based on the particulate level. The PMT2 offers 6 sensitivity ranges allowing the user to choose the range that will best fit the application. The range and test selector switch can also be set to output a 4 mA or 20 mA signal to assist with set up or trouble shooting. Averaging time setting can be used to dampen the signal if desired.

Applications:

• Emissions monitoring
• Broken bag detection in dust collectors
• Filter leak or wear detection
• Bin vent monitoring

Features:

• Simple 2-wire installation for PLC and control panels
• Non-stick PTFE coated probe to prevent false readings from moist and conductive dusts, condensate, and dust buildup
• Remote zero calibration helps to decrease maintenance time

The Series CCS Current Switches are ideal for monitoring the operating status of fans, pumps, and motors. These self-powered switches can be hung or tied directly to cables or wires. For use on existing installations, split core models can be installed without disconnecting cables. LED indicators provide a visual confirmation that the current is flowing through the core. Both fixed and adjustable set points are available. The adjustable models utilize a potentiometer to easily adjust the set point.

Features:

• Integral mounting flange for quick installation
• Solid core or split core configurations
• LED Indicator
