The RelayCard general purpose relay models come in 2 form C, 3 form C, 4 form C, 5 form C and 6 form C. All models are designed to be direct replacements for vapor style relays. No modifications to the electrical system. Models that incorporate Molex connector will need pin terminations installed the first time. Installation kit available that includes plug connector, pins and crimping tool. The RelayCard models all use the same 22 pin molex style connector.
The 4 form C relays and larger use 2 molex style connectors. The 22 pin connector allows 2 termination points for each circuit just as a fast-on has 2 tabs per circuit and use of a 3 form C load relay socket. This makes installing a circuit at any time an easy operation, just terminate with pin and install into plug connector. 2 form C load relays can be upgraded to 3 form C at any time. RelayCard interlocks can be paralleled or as an option high current models are available to 30 amps or more. 2 form C and 4 form C models have magnetic blowouts with load switching to 150 Vdc. All models incorporate over voltage protection that drops out relay over 90 Vdc to protect contact tips.

The versatility that was designed into the RelayCard makes it appealing for use in both old and new locomotives and with the ability to be controlled with CMOS or TTL signals makes it the perfect choice for integration into computer control systems. The RelayCard V is designed for the customer that wants a single vapor style replacement relay. It is the same size and shape as a vapor style with the same fast-on configured top. It incorporates most of the same features as the RelayCard with a plug and go package. Whether you buy from the middle man or direct from vapor chances are Relay Systems Inc. can save you money. We offer Quality, low cost relays utilizing modern patented technology and all competitively Made in the USA.
RelayCard 8 model pictured above. This one is mounted on a one foot square mounting base complete with integral tie bars. 4 base mounting bolts are all thatís required to install the RelayCard. The model shown above has seven 3 form C and one 6 form C load relays installed. Also pictured above is an adaptor harness with molex style connector on one end and shielded female fast-ons on the other end. This allows use of molex style connector without having to install pin terminations on existing locomotive wiring harness.
