SERIES 3868 , DWYER ,Tell Tale Jr.™ Open Heater Detector

Indicates Open Loads

The Tell Tale Jr.™ Open Heater Detector is designed to indicate an open heater or other resistive load. Several models are available for various applications. The LED models light an LED when current is flowing in the circuit. If current stops flowing, the LED turns off. Solid state switch models provide either a logic output for DC applications or a triac output for AC applications. These models will satisfy those applications that need to send heater data to a PLC or computer having an appropriate power supply. They are provided with 4 foot leads. If the triac output model is used to drive an inductive load (relay coil, etc.) then the 3138-0412 snubber network is required. While the Tell Tale Jr.™ Detector is self-powered there is no power loss in the monitored load circuit when installed.

Series DCTE , DWYER , Photohelic® Switch/Gage On-Demand Cleaning Controller

Reverse Pulse-Jet Cleaning Initiated by Differential Pressure

The Photohelic® Pressure Switch/Gages On-Demand Cleaning Controller provides a simple, complete dust collection control all in one enclosure. The Photohelic® controller combined with the DCT500DC Timer Control provides a timed energization of solenoid valves when the differential pressure indicates filter cleaning is necessary. The operator can easily set the cleaning initiation and duration by adjusting the 2 set point knobs on the front face of the Photohelic® controller. Solenoid valve sequencing is also easily set via two potentiometers inside the enclosure on the timer board. A three position switch on the front of the enclosure offers cleaning versatility by allowing the user to select between on demand or continuous manual cleaning. The Photohelic® controller is pneumatically connected with tubing to fittings on the enclosure. All that is required for start-up is connection of tubing from the process to the external fittings on the enclosure, and wiring the solenoid valves to the timer board.

Series DCT1000DC , DWYER , Dust Collector Timer Controller

For Low Voltage Applications

Simplify your on-demand cleaning requirements with the Series DCT1000DC Dust Collector Timer Controller. Relying on one timer board for on demand and continuous cleaning applications, the DCT1000DC eliminates external devices such as pressure switches, relays and timers.

The DCT1000DC accepts 10-30 VDC power. The units modular design allows for use as a continuous cleaning control or on demand cleaning control using the optional DCP plug-in pressure module. A 4-20 mA process output is integral to the DCP pressure module, eliminating the need to purchase an expensive process transmitter. A solenoid fault light on the DCT1000DC notifies the operator when a solenoid valve fails to activate properly.

The DCT1000DC is the same size for 6, 10 and 22 channels. One board size allows the standardization on one enclosure.

DCT600 , DWYER , Timer Controller

With Universal Power for Both 120 and 220 VAC

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.
