Send a signal to turn equipment on and off from up to 150 feet away without having to run electrical wire. These relays have an enclosure to protect the terminals from dust and accidental bumps. They can be set to transmit, receive, or both at once. You’ll need at least two relays to switch a device. They have an alarm that can be set to check for certain conditions before transmitting a signal. For example, you could set these relays to send a signal to turn on an air conditioner if all windows are closed. The repeat function extends the transmitting signal through a maximum of two receiving relays.

Relays that are set to transmit can be linked up to as many receiving relays as you need. Relays set to receive can be linked up to 30 transmitting relays. All relays connect to dry contacts on your switch, sensor, or controller. Use the wire leads to connect them to a power source.

UL and C-UL listed, all meet American and Canadian safety standards. Rated NEMA 1, they should only be used indoors.

The NEMA 4X rated enclosure protects these starters from corrosion and washdowns. They provide on/off control for a motor and protect it from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.

Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s power and voltage).

Sized to fit in tight spaces, these starters have a shorter height and narrower depth than most other starters. A NEMA 4X rated enclosure protects them from corrosion and washdowns. They provide on/off control for a motor and protect it from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.

Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns. Use them with motors that run forward and backward, such as motors for conveyor belts. They provide on/off control and protect motors from overloads—starters will shut the motor off if current exceeds the full-load current rating. Set the adjustable overload relay for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light.
