Parameters of miniature DC relay
Coil DC resistance: The resistance value of the coil measured with a multimeter. Rated operating voltage or current: This refers to the voltage or current value of the coil when the relay is operating normally. Sometimes, the manual only provides the rated operating voltage or current, in which c...Read more -
Other classifications of relays
II. Classification by external dimensions Miniature relay:A relay with a longest side dimension not exceeding 10mm. Subminiature relay:A relay with a longest side dimension greater than 10mm, but not exceeding 25mm. Small relay:A relay with a longest side dimension greater than 25mm, but not exce...Read more -

Acromag offers relay interface modules for monitoring or controlling high power (on/off, high/low, on/off) drives using remote I/O, PLCs, or other distributed control systems with DC logic signals. Wixom, MI, May 8, 2013 /PRNewswire/ — A...Read more -
PLC Relay module
Recently [Manuel] published an article about creating logic gates from anything. He referred to a web site about ladder logic. While you can indeed create logic gates using switching logic (i.e. two switches in series is an AND gate, two switches in parallel is an OR...Read more -
Classification of Relays
There are various methods to classify relays, including based on operating principles, physical dimensions, protection characteristics, contact load, and product applications. Classification based on operating principles: Electromagnetic Relays: Relays that generate a predetermined response th...Read more -
Symbol and Contact Forms of Relays
The coil of a relay is represented by a rectangular symbol in the circuit. If the relay has two coils, two rectangular symbols are drawn side by side. The relay’s letter symbol “J” is marked inside or next to the rectangular symbol. There are two ways to represent the contacts ...Read more -

About Relay Testing
Relay Testing: 1. Testing contact resistanceUsing a multimeter in resistance mode, measure the resistance between the normally closed (NC) contact and the movable contact. The resistance should be 0 ohms (using a more accurate method, the contact resistance can be measured within 100 milliohms). ...Read more -
Main parameter of relays you should kow
Main Technical Parameters of Relays 1. Rated working voltage Refers to the voltage required by the coil of the relay during normal operation. Depending on the type of relay, it can be AC voltage or DC voltage. 2. DC resistance Refers to the DC resistance of the coil in the relay, which can be me...Read more -
Electrical Encyclopedia: Relay knowledge points that electricians must know
1. Definition of relay: a type of automatic control device that causes a jump-change in the output when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. 1. The working principle and characteristics of relays:When the input quantity (such as voltage, current...Read more -
