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 1, 3, or 5-Amp DPDT Relays with relay status LEDs. Power this controller using 12VDC from the 2.1mm barrel connector or the 2-wire terminal block.
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.

This product may have been previously manufactured using a part number shown below:
This controller offers an optional 1-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 1 Amp. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 1-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 16 AWG wire. Review Datasheet
This controller offers an optional 3-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 3 Amps. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 3-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 14 AWG wire. Review Datasheet
This controller offers an optional 5-Amp signal relay, allowing control of signals up to 12VDC at 5 Amps. Ideal for audio, telecommunications, and light-duty power switching applications. This relay has a low On resistance. The 5-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 14 AWG wire. Review Datasheet

Compatibility Notes
When using an 900HP-S3B communication module, it is essential that you use the ZIGMO_PCB to configure the module settings. Long-Range wireless sensors may be programmed over the air without removing the communications module.
A 900HP-S3B Modem or a gateway of some kind that support the 900HP-S3B communications module will also be required.
The NCD RS-232 Serial communications module is compatible with standard RS-232 signals (+/-10VDC), which are not directly compatible with UART signals from a microprocessor. If you are working with Arduino, Microchip PIC, or other common microcontroller, a communications module is not required. Microcontrollers will directly talk to the on-board processor of all NCD controllers.
