They follow guidlines setup by an electrical standards guidelines. When the coil of the relay is at rest (not energized), the common terminal (30) and the normally closed terminal (87a) have continuity. Terminal number 86 supplies voltage to the coil side of the relay. Colorful Ceiling Fans With Lights. DIN standard 72 552 establishes the terminal numbering system that's used for any wiring diagram or vehicle wiring that conforms to DIN specifications. A 27/59 device, for example, is a combination under/over voltage relay. In fuse box starter relays, the ground is terminal 86. For example, a low power circuit in a car that commands the high power headlights to come on would send the command through a 4 terminal relay. I can't remember the organization that standardized the numbers system specifically, but essentially, there is a guide that tells how the numbers are assigned based on funtion and timing (when it was proposed and approved) Something like how the NFL uses certain sets of numbers for certain positions. c3controls’ Terminal Block Relays were developed to meet your switching requirements in highly sophisticated control and automation systems. That is, the COM terminal gets connected to NO terminal. Identify the terminal block and relay numbering for the DO signal as per Instrument wiring interconnection drawing and Electrical schematic wiring drawing. In the next section, a demonstration on identifying the pins of a relay from SPDT or DPDT type without referring to its datasheet will be illustrated. the number of terminal designations as per DIN 72552 no longer suffice, are num-bered by consecutive numbers or letters whose function assignment is not speci-fied by standards.
