Progressive Dynamics DPDT 110VDC Relay 102084

Replaced by PD110902

Contact points are rated at 30 amps per pole 110 VDC coil DPDT (double pole, double throw) relay. Used in all 30 Amp Parallax ATS, Todd TS-30, and Progressive Dynamics 700 series converter transfer switches.

 

The coil used to pull down the contact points of this relay is rated 110 VDC, usually you will read about 110 to 160 VDC the coil itself can be checked by ohming it out. Anywhere between 5000 to 6000 ohms on the ohm meter is good, outside that range, REPLACE THE RELAY.

What do SPST, SPDT, DPST, and Progressive Dynamics DPDT 110VDC Relay 102084 mean?

SP and DP refer to single pole and double pole, ST and DT refer to single throw and double throw.

Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked). Do not confuse ‘pole’ with ‘terminal’. The DPST switch, for example, has four terminals, but it is a DP, not a 4P switch.

Throw refers to the extreme position of the actuator: ST switches close a circuit at only one position. The other position of the handle is Off. DT switches close a circuit in the Up position, as well as the Down position (On-On). A DT switch can also have a center position (frequently On-Off-On).

Single pole/throw and double pole/throw switches are by far the most common switches, but triple and quadruple configurations are also available. They are commonly denoted 3PST, 3PDT, 4PDT, etc.
