DC Block Occupancy Detector

DC Block Occupancy Detector

This module detects the presence of a train and sends a signal to the Signal Controller. In addition to informing the signal controller that the block is occupied, the detector can be used to illuminate an LED on your panel board to show occupancy. It...

DCC Block Detectors

ISS is a dealer for multiple DCC manufacturers. We offer different detectors at various prices. We have used and installed all of the detectors listed. NCE BD20. $12.00 ea. The BD-20 block detector module is normally used to indicate the presence...

Power Supply

ISS at one time manufactured our own 1.5 and 5 amp power supplies. With the growth of commercial electronics, we have been able to acquire better power supplies that outshine our old designs. We still offer a 1.5 and a 5 amp supply, but we have added...

Signal Controller

Each controller operates two signals, one in each direction, or two heads on a multi-headed mast. The system is bi-directional on single track. Signals perform exactly like prototype ABS (Automatic Block Signal) signals. CTC (Centralized Traffic...
Signal Interface Module (SIM)

Signal Interface Module (SIM)

The ISS Signal Interface Module is used to convert signals from Common Cathode to Common Anode. Each module will invert four LEDs, and each LED can be turned on from two sources. Each of the independent circuits contains a transistor which acts as...
Turnout Module

Turnout Module

The Turnout Module is used in conjunction with the ISS Signal Controllers, SCA-2ä, SCA-3ä, SCA-4ä, SCA-5ä, whenever it becomes necessary to signal a siding or a diverging route. The board uses the latest in surface mount technology and has screw ter...
