Legacy Universal 2-Channel 20A SPDT Relay Controller
NCD Low-Cost Universal Relay Controllers
Whether you are looking for wireless or USB relay control, NCD universal relay controllers feature a no-frills design that supports relay on, off, and relay status commands. NCD Universal relay controllers communicate any of our communications modules that operate at 9600 baud. This relay controller features 2-Channel 20-Amp SPDT or 30-Amp SPST Relays with relay status LEDs. Power this controller using 12VDC from the 2.1mm barrel connector or the 2-wire terminal block.
Universal Interface
This Low-Cost relay controller features a modular communications interface supporting most of today’s most popular communication technologies. Choose your favorite technology now, change it later as your needs change.
Choose a USB interface for basic USB relay control using a virtual COM port communicating at 9600 baud.
Choose a Serial interface for RS-232 relay control operations at 9600 baud.
Choose a Bluetooth interface for Bluetooth relay control applications using the Virtual COM Port Driver stack.
Choose a ZigBee, 900HP-S3B, 802.15.4 interface for Wireless relay control. These options require an external that communicate to the USB port of your computer.
Choose from any of the following communication modules:
802.15.4 Long-Range Wireless
Use 802.15.4 Communications if you require industrial strength long-range wireless communications. 802.15.4 is a point-to-point wireless standard, allowing fast communications. The wireless protocol acts as a long-distance wireless serial port, allowing wireless operation with no modification to software.
900HP-S3B Industrial Wireless Mesh
Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This communication module will hop data from one location to another to reach its intended destination. Data hopping is a integrated feature of this communication technology, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in our products, as this is the best the industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away.
RS-232 Serial
NCD RS-232 Serial Communication modules make it easy to integrate the worlds most prolific communication standard. Easily interface to desktop PCs and laptops for easy control via standard serial commands. Most NCD devices typically default to 115.2K Baud; however, older low-cost devices implement 9600 baud data rate as the predominate standard.
USB
Our USB interface module makes it easy to control our devices using the USB port. Simply plug into any available USB port and start controlling our devices using standard serial commands. NCD USB Interface modules feature genuine FTDI USB to Serial Converter Chips, the very best in the industry.
ZigBee® Wireless
ZigBee® wireless communications is a popular standard among our customers. The wireless protocol acts as a long-distance wireless serial port, allowing wireless operation with no modification to software.
20-Amp SPDT Relay Option
This controller is available with a 20-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 20 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 20-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay. The relay is molded with COM, NC, and NO markings into the plastic.
30-Amp SPST Relay Option
This controller is available with a 30-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 30 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 30-Amp relay is of the SPST variety, which provides Common (C) and Normally Open (NO) connections. Common has no connection when the relay is off. Common connects to NO when the relay is activated. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay. The relay is molded with COM, NO markings into the plastic.
