Time Activated Relays


Our Time Relays are equipped with firmware built into the board that will allow you to setup a time schedule to trigger relays. You can set this schedule up using our Base Station Software with a simple click through interface. Optionally you can choose to override this schedule over the communication interface of your choice.

  • Controller Knows What Time it is
  • Set Time Schedule with Included Software
  • Trigger Relays all at Once or in Sequence
  • Up to 999 Events Can be Configured
  • Computer Can Take Control at Any Time
    •  Override Settings for Special Events
  • Computer can Read Status of Relays
  • Once Configured Controller Can Operate Without a Computer

Time Controlled Relays - Taralist

Time Activated Relays are our most popular self-automated Relay Controller. They are simple to use, overrideable, and reliable.

Our Time Activated Relays are equipped with Computer Controlled firmware built into the board that will allow you to override one relay at a time, a bank of relays or all relays at once with manual and automatic refreshing command set.

These Real Time Clock Relays or RTC Relays are as powerful as they are versatile.

Why Choose NCD?

With NCD you know you have a proven reliable, easy to use, and extensible product because we’ve been in the business for over 20 years. This means you don’t have to spend valuable time researching how to jig-saw pieces of your project together to get them to work cohesively. Being manufactured in the U.S.A. you know you’ll get good support and a quality product. NCD also ensures you won’t have to put any time into soldering or building a PCB, just pick your boards and power them up. Knowing that every sensor, relay controller, and component is built around the same concept will save you guess work on how well software will work with any board.

How it Works

Put simply, our Time Activated Relays activate and deactivate relays based on a schedule. These schedules can be changed at any time or can be overridden by a computer control command.

The communication port allows you to choose from any of the Interface Technologies we talk about below and can be used for anything from Configuration and Serial Control to Cloud Control.

Communication Options

Selecting a Communication Technology

The Communication Technology you choose will dictate how you will control and monitor the board. If you want to monitor over a LAN or WAN you can choose WiFi, Ethernet, or Web-i. Need wireless control? Choose S3B, Bluetooth, 802.15.4, or ZigBee Mesh. Want Reliable Wired communication? Choose USB, Serial, or RS-485.

The choice is yours and can change to suit your application.

WiFi Relays​

Much of our development work was done with embedded Wi-Fi. Put simply, we adore this technology and we think you will too. Configuration requires careful attention to our instructions, but once configured…wow. It’s simply amazing and holds so much promise for future development work.

We are working to make configuration easier, but for now, plan on reading our manual found on the product pages BEFORE purchasing. Configuration requires a WiFi Configuration Kit.

S3B Long Range Wireless​ Relays​

Digi XBee-PRO 900HP embedded modules provide best-in-class range wireless connectivity to devices. They take advantage of the DigiMesh® networking protocol, featuring dense network operation and support for sleeping routers, and are also available in a proprietary point-to-multipoint configuration. Supporting RF line-of-sight ranges up to 28 miles (with high-gain antennas), and data rates of up to 200 Kbps, these modules are ideal for extended-range applications requiring increased data throughput.

Digi XBee® modules are easy to use, share a common hardware footprint and are available in a variety of different protocols, enabling users to substitute one Digi XBee for another with minimal development time and risk.

Bluetooth Relays​

We offer Bluetooth communications because of its popularity with mobile devices. If you want to control relays with your smartphone (and you are savvy at writing such an application), then Bluetooth is the ideal choice. iPhone, iPad, and iPod developers should be warned, Apple iOS devices encrypt the Bluetooth protocol deliberately, so our Bluetooth interface is compatible with every computer ever made, including Android, PCs (and every version of Windows that supports Bluetooth), and Linux (and all variants thereof that support Bluetooth), but it will NEVER work with Apple iOS devices.

802.15.4 Relays​

This is one of our favorite wireless technologies. It is easy to setup and use and very reliable. You need a 802.15.4 modem that plugs into your USB port to talk any number of 802.15.4 Wireless relays with up to 1 mile range! You can purchase a modem with the device you choose.

Serial Relays​

Serial communications may seem like old hat, but they’re also one of the most reliable and proven communication protocols available and are in fact the basis of most of the other communication options here.

You can choose between a Serial DB9 Connector or a 3 wire terminal connector for simple wire hookups. DB9 is the standard serial connector while the 3 wire terminal is usually more advanced and for existing ECM’s and serial splicing applications.

USB Relays​

When it comes to ease of use, USB can’t be beat. With the reliability of Wired Communications and the pure simplicity of USB Technologies this is one of our most popular interface technologies.

To use USB simply plug it in to your computer/ECM, the driver should automatically be installed or already be installed, and open a COM/Serial Port to it. We use an industry standard FTDI chip for added reliability and compatibility across all Operating Systems.

Ethernet Relays

Ethernet communications combine the reliability of a wired connection with the power of network communications. Control your devices reliably from anywhere in the world by implementing a simple socket directly to the device.
