The Leviton Relay-2CB and Relay-2TD are versatile and high-performing lighting relays specifically designed for residential and light commercial applications. These relays offer two independently controlled channels, making them suitable for controlling multiple lighting circuits or loads.
The Relay-2CB is the coffee version of the two, designed for use with dry, standard household electrical circuit wiring. It comes with two separate Common/NO (Normally Open) contact sets, allowing for the independent control of two separate lighting circuits. The contacts can handle up to 10 amps at 125 volts, making them ideal for controlling incandescent, halogen, LED, and other types of lighting loads.
The Relay-2TD, on the other hand, is designed for use with 20 amp, 120/277Vac, or 120/208VAC, 3-wire, NEMA 5-15R or 5-20R, GFCI, or duplex receptacle-connected loads. This model comes with two separately interchangeable NO/NC (Normally Closed) contact sets. Like the Relay-2CB, this relay is also well-suited for controlling various types of lighting loads.
Both models feature a standard touch-latch design, which allows the user to easily incorporate these relays into exterior or non-locatable junction boxes. They also come equipped with golden-contacts, which ensure a long contact life, and a high contact today of 1,000 operations at 125 F (51.6 C), ensuring reliable performance even in demanding conditions. The relays operate at a low voltage of 5Vac or 12Vdc, and they feature a coil current consumption of 230mA at 10Vdc.
These relays are UL and CSA listed for use in the United States and Canada, and they meet the requirements of the National Electrical Code (NEC) and Canadian Standards Association (CSA) standards. They are an excellent choice for various residential and light commercial lighting control applications, offering twin-channel functionality, high performance, and reliable operation.
The Leviton Relay-2CB and Relay-2TB are popular choices for those seeking to control lighting circuits efficiently. Let's explore the key advantages and potential drawbacks of incorporating these relays into your lighting project.
1. **Relay-2CB:** Pros:- **Compact Size:** Comes in a compact design, making it easier to install in confined spaces.
- **2 Form C Relay Contacts:** Allows you to control two separate circuits with a single relay, reducing the number of components required.
- **High Load Capacity:** Can handle large electrical loads of up to 15A per contact, serving various lighting applications.
Cons:- **Requires a Normally-Open (NO) or Normally-Closed (NC) contact:** Needs a contact that completes a circuit to turn on or off the load, which might add to the complexity of the installation process.
2. **Relay-2TB:** Pros:- **Twisted-Pair Monitoring:** Allows the monitoring of two separate circuits with a single relay while also providing fault detection.
- **Reduced Wiring Complexity:** Eliminates the need for multiple control wires by combining control, neutral, and load wiring into a single pair of twisted-pair wires.
- **Compact Size:** Similar compact design as the Relay-2CB.
Cons:- **Higher Cost:** Slightly more expensive than the Relay-2CB due to the added functionality of twisted-pair monitoring.
Conclusion:Both the Leviton Relay-2CB and Relay-2TB are efficient solutions for controlling lighting circuits, but they cater to slightly different needs. If you require simple switching of two separate circuits, the compact Relay-2CB is a cost-effective choice. However, if monitoring and potential fault detection of multiple circuits is a priority, the Relay-2TB with twisted-pair monitoring delivers the added benefit.
Recommendation:Based on the outlined pros and cons, the Leviton Relay-2TB is our recommendation. The added functionality of twisted-pair monitoring offers flexibility and peace of mind for your lighting project. But, if your project does not require monitoring, the Relay-2CB is a more budget-friendly alternative. It's crucial to consider the specific requirements and constraints of your project before making a decision.
This Leviton lighting relay is a top-of-the-line product for industrial and commercial needs.
