How to Set Up and Record with a SCD and Mini-Node™ Signal Converter

The DIN Rail Temperature/Process Controller, Series SCD, offers multiple PID loops in a compact size. Each SCD-1000 master controller can be combined with up to seven SCD-2000 slave controllers without any wires. Each controller has one universal input, one relay output, and one user selected output.

The Series SCD can be used with a Mini-Node™ Signal Converter for applications such as: oven, boiler, or chiller control; packaging equipment; environmental chambers; medical equipment; or food service equipment. The Mini-Node™ converter, Model MN-1, is a low cost device that converts half duplex RS-485 serial communications signals into a signal that can be read by any computer with a USB port.

Wiring up the MN-1 to an SCD controller can be accomplished in just a few steps, and the set up software is simple to use. Continue reading “How to Set Up and Record with a SCD and Mini-Node™ Signal Converter”

Proving Water Flow in Rooftop Air Handlers

We met with an original equipment manufacturer (OEM) last year, who was working on a new design for rooftop air handling equipment. Part of the their design utilized water flow for cooling in a loop.

Low or no-flow conditions can cause major damage to expensive pumps, motors, and other equipment, which could result in extensive downtime and repair costs. In order to prevent this, the customer needed an inexpensive, but reliable and robust method for proving water flow. Continue reading “Proving Water Flow in Rooftop Air Handlers”

The Key to Energy Efficiency

“In the real estate industry you always hear this phrase, ‘Location, location, location.’ I think for energy management systems the key is ‘Execution, execution, execution.'”[1]

— Sara Lisauskas, Energy Management Systems: Maximizing Energy Savings

What comes to mind when you think of the phrase “energy efficient?” Perhaps you think of LED light bulbs, electric cars, Energy Star appliances, or LEED-certified buildings. But energy efficiency isn’t limited to “green” products or certifications. Continue reading “The Key to Energy Efficiency”
