Relay Options
10-Amp SPDT Signal Relay Option
This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-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. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet
5-Amp SPDT Signal Relay Option
This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 5-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. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet

Learn how to find the COM Port on your windows based computer. You can also use Base Station to find the COM Port of your Relay Controller. Base Station can be downloaded at ncd.io/start.
Introduction to Relay Control
This video will guide you in determining which relay controller you need for your application as well as a general overview of the differences between Relay Options. If you’re new to our products or just need a refresher for a new application this is a great place to start.
Induction Suppression
Learn about Induction and how it comes into play with Relay Controllers. Induction suppression can make your Relay Control applications intermittent and unreliable. This video will show you what causes it, how to avoid it, and how to account for it in your application.
900HP-S3B Wireless Compatibility Notes
Notice: Compatibility Notes Does NOT Apply to the Following Products:
- NCD Enterprise Solutions
- NCD Wireless Sensors
- NCD Enterprise Modems and Gateways
Notice: Compatibility Notes Applies to NCD Industrial Products, Including Fusion, ProXR, ProXR Lite, Taralist, and Reactor Series Products.
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.
RS-232 Serial Compatibility Notes
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.
