These innovative 3-in-1 products expand proven logic control capabilities into versatile new controllers.
DANBURY, Conn. (PRWEB) January 20, 2023
Preferred Utilities Manufacturing today announces the addition of three new products to their esteemed JC line of draft controllers and monitors.
The JC product line features off-the-shelf programming with user-selectable features for quicker lead times and commissioning. All setup can be done from the 5-inch LED touchscreen. Each JC controller includes a 50-point time/date-stamped alarm history and ethernet communications, and they have a depth of 4.88 inches for shallow panel mounting. JC products can be updated in the field via a USB connection and Preferred’s JC_TG_Edit software.
The new JC 3-in-1 products combine the proven control logic from Preferred’s JC line into three versatile controllers: the JC-13D2, JC-23D2, and JC-33D2.
JC-33D2:
The JC-13D2 is a 3-channel process bargraph indicator that can accept up to three high precision analog input signals of the following types: 4-20 mA, 0-2.3 Vdc, 0-5 Vdc, 0-10 Vdc, 10k thermistor, type J thermocouple, and type K thermocouple. Each channel is fully customizable with configurable scaling, custom user labels, and alarms. The home screens can be set to show each individual bargraph, all three bargraphs at once, or the no-bargraph large number screen for high visibility. Featuring a bright color LED touchscreen display, the JC-13D2 is fully configurable from the easy-to-use menus, with additional I/O for alarms and 4-20mA output.
JC-23D2:
The JC-23D2 is a boiler performance controller that combines flue gas temperature monitoring, draft control, and opacity monitoring in an all-in-one unit. The opacity monitoring logic integrates directly with Preferred's 190851S and 190851D light source and detector, and it can be setup for either standard or NYC-BAR opacity shutdown sequence. The JC-23D2 is fully configurable from the bright, color LED touchscreen display with settings for flue temp alarm and shutdown, opacity alarm and shutdown, adjustable draft start position, firing rate feedforward PID draft control, draft servo auto-calibration, opacity auto-calibration, and more.
JC-33D2:
Up to three stacks can be monitored at once with the JC-33D2 3-in-1 opacity monitor. Expanding on the user-friendly features of the JC-30D2 (such as the auto-calibration and auto-range functions), the JC-33D2 includes the necessary logic and I/O to monitor the opacity of up to three boiler stacks with either the standard or NYC-BAR shutdown sequence, with an independent burner shutdown relay for each of the three opacity channels, all from a central controller. The JC-33D2 is fully configurable from the bright, color LED touchscreen display, and it can be set to display each individual channel or all three channels at once.
These three additions to Preferred’s product line are available now. For more information, visit Preferred’s website at http://www.preferred-mfg.com.
