Discontinued

This product has been discontinued.  When existing stock is depleted, we will not build any more except by special arrangement.

Fully integrated and ready-to-use, the MSS-CASCADE contains everything needed to add simple Automatic Block Signaling (ABS) to your layout or module.  No programming required!  Designed for use at a a block boundary, it provides the Cascade function of the Modular Signal System standard.   The MSS-CASCADE integrates two highly-reliable current-based DCC block detectors, an optical detector based on the foolproof Iowa Scaled Engineering CKT-IRSENSE, pre-programmed control logic, LED signal drivers, a rugged and reliable MSS bus interface, and plug-and-play RJ45 connections.

Features

• Completely integrated - no additional detectors or signal driver boards required
• Fully compliant with the Modular Signal System 2.0.0 standard
• Easy installation with connectors and terminal blocks
• Dual current-based DCC block detectors with adjustable sensitivity
• Isolated detection to prevent coupling track power and signal systems
• Integrated, highly reliable optical detector
  
• Capable of driving a wide variety of signal heads
• 3 LED common anode (+)
• 3 LED common cathode (-)
• Red/green single LED, 3 wire common anode (+)
• Red/green single LED, 3 wire common cathode (-)
• Red/green single LED, 2 wire
  
• Supports single or dual headed signals for each direction
• Supports MSS “diverging approach indication”
• Configurable signal aspects and approach lighting
• Auxiliary occupancy input for both A and B blocks
  
• Rugged and reliable MSS bus drivers
• Plug-and-play RJ45 connections
• Powered from 8V to 20V AC or DC accessory power
