Fan Out Board, Direct Drive) This board is specifically designed to direct drive eight LED's from a single RR-CirKits port. It includes on board locations for current limiting resistors and jumpers to select common anode or common cathode connections. No...

This RGY LED is provided with four 24" long color coded #36 AWG wires. It may be fitted in place of a common T-1 LED with room to spare. The LED provides the three standard searchlight signal colors and is wired the same as a normal three light signal...

This board is normally used for block detection on three rail layouts. This version of the board includes internal current limiters. Useful anyplace that an external voltage needs to be monitored. (5V-20V AC-DC-DCC)

Relay Board - 4 is a Quad 10A SPDT relay board with logic level drivers. It is suitable for use with TC Mark II, TowerMan, Tower LCC, or other logic level output devices. It requires 12V auxiliary power to supply the relay coils. Auxiliary power is...

(Single Coil Solenoid Driver) This 8 line, optically isolated, single ended, high current, high voltage DC driver can drive up to 1A continous per line at up to 30VDC. When used with custom Tower LCC settings and a CD power supply this board will drive 4...

(Stall Motor Driver) LCC sample mode compatible. This 8 output, optically isolated, low current "H" bridge driver is designed for control of 8 stall motor switch machines. (E.g. Tortoises®) It can drive up to 100ma. per line, speed regulated output 6 to...

(I/O Test Board) This board contains 8 push button switches and 8 LED pairs. It is designed to quickly test the I/O ports on any of our boards such as the Tower LCC, Mark II, various of the WorkMan series SSB boards, and our LCC I/O nodes. It may be...

Single CT (Current Transformer) coil.

Set of 4 CT (Current Transformer) coils for BOD4 or BOD4-CP.

Set of 8 CT (Current Transformer) coils for BOD-8. These 100:1 toroid coils sense the track current on leads passing through the hole in the middle of the coil. They connect to the BOD-8 with twisted pair cable such as CAT-3 or CAT-5 network cable. (up...
