Overview
The Train-Tech RL1 Relay Controller incorporates two built in relays to switch high power low voltage
loads controlled by Track Sensors, Sensor Signals, Mimic Switches or DCC Accessory commands.
Please read these instructions carefully.
Connections
Underside – Foam pad
This protects connections
and provides insulation
from circuit board heat.
DO NOT REMOVE PAD!
Instruction manual contents:
• Overview with Connections and Troubleshooting:
• Relay control using Track Sensors or Sensor Signals (can be powered by DCC or DC)
• Relay control using DCC Accessory Commands (DCC only)
• Relay control using Mimic Switches (can be powered by DCC or DC)
• Connecting to the relays – hints and tips on how to connect devices to be controlled
• Automatic Train Control for multiple trains using a Sensor Signal or Track Sensor
• Automatic Train Control for a single short stop using a Sensor Signal or Track Sensor
• ABC Braking for DCC Automatic Train Control
Caution - only ever connect with all power turned off and ensure you never touch any
other connections or components otherwise permanent damage will result.
Troubleshooting
This product is designed to be easy to connect and use but here are a few tips which may help should you
have problems following installation. Remember only ever wire and install with all power turned OFF.
• If wishing to control Relays using DCC Accessory addresses you must first set your DCC controller to
accessory command mode to set up and use it – refer to your controller manufacturers instructions.
• Use adequate thickness cables to connect Relay outputs to the models it is controlling.
• Please note that it is normal for the base of the Relay Controller to get very warm – do not remove the
foam base which is fitted for protection and allow space for adequate airflow.
• Note that you should include appropriate suppression particularly for trains, motors and solenoids using
capacitors, chokes etc to prevent interference to other train control products and domestic appliances
•
• ABC braking technology is complex and setting up CV commands and wiring Diode modules correctly
varies between DCC decoder manufacturers, so refer to their detailed instructions for specific decoders.

- Page 1 Please handle carefully & read these instructions fully before using!! Overview The Train-Tech RL1 Relay Controller incorporates two built in relays to switch high power low voltage loads controlled by Track Sensors, Sensor Signals, Mimic Switches or DCC Accessory commands.
- Page 2 Track Sensor or Sensor Signal – solid core 1/0.6mm wire is ideal as it just plugs into the sensor/signal and is as supplied by Train-Tech (WP2/WP3) or model or electrical stores. The Relay Controller and Track Sensors/Sensor Signals can be powered either by DCC or smooth DC –...
- Page 3 (or on some controllers 1 or 2 or left or right direction). To assign an accessory address to each of your Relays connect the RL1 to the standard DCC track power output, set your DCC controller to Accessory control mode and turn on DCC power.
- Page 4 DC Note that a useful feature is that if a Mimic Switch is connected to an RL1 as well as a Track Sensor or Sensor Signal to the same relay, then the occupancy LED (LED B) on the Mimic Switch will light...
- Page 5 (in between) power and whatever you are controlling. The drawing below shows the internal relay contacts inside the RL1 so that you can see how they relate to a switch. The common (COM) terminal is the contact which moves and the other two terminals are Normally Open (NO), which means it is only connected to the COM terminal when the relay is activated, and Normally Closed (NC), which means it is connected to COM when the relay is not activated.
- Page 6 The illustration below shows how to wire two Sensor Signals and two stop sections to an RL1 to stop trains when they come up against a red signal. This shows just two stop sections, but it can be scaled to many more in the same way, either end to end or continuous ovals.
- Page 7 DCC power, and these can be used with the Automatic Train Control projects for RL1 so that trains slow down instead of suddenly stopping. However note that the ABC diode modules only work with DCC locos fitted with configured ABC decoders and none-ABC chip fitted locos will not slow down or stop in isolated sections where ABC diode modules are installed.
