What are switching relays?

Switching relays are commonly. used devices in a variety of HVAC/R applications. Typically they are used to switch light current loads, ranging from fan motors to damper controls. A relay is a device that acts as a remotely controlled switch.

What does PCB relay stand for?

PCB Power Relay Features Power relays for printed circuit boards offer superior performance in high-capacity load switching in the power supply system owing to its material that can resist to contact arc and single contact structure (see figure).

How do you know if a relay is working?

Here’s How To Test a Relay

  1. Locate the relay you need to test.
  2. The quickest and easiest way to test a relay is to swap it out with a known good replacement.
  3. Grab a multimeter and set it to Ohms.
  4. Leave the multimeter on ohms or continuity.
  5. Energize the electromagnet coil with a 9-12V battery across the pins.

What are the different types of Omron relays?

Omron offers several different types of relays to meet your needs. Below, you’ll find the different types of relays that we have available. PCB Relays for switching current 2A max.

What are the different types of Allen Bradley relays?

Time delay, latching attachments, overlapping, and logic reed contacts can be combined into one relay to yield a custom-tailored application solution. Our Bulletin 700S-P and 700S-PK Safety Control Relays are designed to meet worldwide safety standards. These relays have mechanically linked contacts and tamper-resistant covers.

What does the Bulletin 700-hta alternating relay do?

Our Bulletin 700-HTA Alternating Relays serve as interposing relays between your controller and field devices. The alternating feature lets you select the primary or secondary load or to alternate between the two. Our General Purpose Electronic Timers and Counters help increase your flexibility, and reduce maintenance and power costs.

What kind of relays are used for DC switching?

Our Bulletin 700-HG Power Relays are suitable for switching DC loads. Our relays are available with an optional magnetic blowout for arc suppression, enabling switching of even higher current DC circuits. Our Bulletin 700-HHF Flange-Mounted Power Relays are small-sized general purpose relays that switch large loads.
