==== Digitrax ====
SE8C Signal Decoder, no longer available. This device requires a computer to control it.
SE74, replacement for the the SE8C.
=== NCE ===
NCE DCC Light-It Programmable DCC Lighting and Signal Decoder
=== Sig-Na Track ===
Was previously known as CML Electronics
LocoNet and DCC messages control these signal decoders
==== SIGM10 ====
Another good board for signal control is the SIGM10 which contains its own logic.
This device is no longer available and has been superseded by the SIGM20.
==== SIGM20 ====
The SIGM20 is an automatic controller for eight signals. It sets the signal state automatically according to the state of the trackwork (turnouts), other signals and block occupancy detectors. It does this automatically, without any other computers involved: No computer is required to operate the railway. The board can control simple blocks, simple and complex junctions ... automatically.
The SIGM20 drives LED signals directly. Via optional adapters it drives incandescent lamp signals or semaphore signals controlled by Tortoise turnout motors. The behaviour for each signal is programmed: thereafter it operates automatically.
* Drives either eight 3-aspect or six 4-aspect signals
* Two more signals can be driven by an optional self-assembled add-on board.
* LED signals: 2, 3 or 4 aspect or "searchlight" type.
* Incandescent lamp signals can be driven using optional adapters
* Semaphore signals operated by Tortoise motors can be driven using optional adapters
* Simulation of "soft" lighting & dimming of lights: brightness ramps up or down over approximately half a second for more realistic looking signal lamps.
* Fully compatible with the older SIGM10 - the two can be mixed on a layout seamlessly

==== Signal Controllers for Dapol Semaphore Signals ==== 
===== SC3 =====
For Original Dapol Semaphore Signals
* Controls one or two Original Dual N or OO gauge motorised Dapol semaphore signals by DCC
* Each signal can be given a separate DCC address with their position controlled by the SC3 which also remembers that position.
===== SC300 =====
Dual Dapol + Track sensor & switch inputs
* Like the SC3, controls Two Original Dapol semaphore signals directly from a DCC track or bus.
* Inputs for Track Sensors allowing Semaphore signals to operate automatically when Trains are sensed on the track!
===== SC4 =====
For New Dapol Servo Semaphore Signals
* Designed to power and control the new Dapol Servo controlled signals with three wire inputs for each signal. 
* Control one, two or a twin head (e.g., Bracket) servo signal
* Assign to any DCC accessory address & run the two arms independently or together in Home-Distant pairs. 
* It also incorporates a regulated power supply to provide a stable safe voltage for the signals from the standard DCC track supply.
* Easy and quick to connect, use and setup using One-Touch DCC.
===== SC400 ===== 
New Dapol Semaphore Dual Servo Signal Controller with Track sensor inputs
* Specifically designed for the new Dapol Servo controlled signals which have three wire inputs for each signal
