Accessory Decoders
Control Turnouts, Lights, and Other Stationary Accessories

Remote control - The AD4 decoder is used to control stationary items such as switch machines, and lights. Any device, equipped with an accessory decoder, can be activated and controlled from any throttle and/or, the command station.

Local push button control - In addition to commands coming from throttles, the AD4 can be activated with simple push buttons. Either a single toggle switch or a pair of push buttons can be used.

4 independent outputs - Each AD4 has 4 paired outputs that can be split into 8 independent outputs.

Supports Operation Mode and Service Mode programming - Configuration of all the decoder features are done via the Command Station's programming track or with "OPS" mode mainline programming. A simple jumper interlock prevents accidental reprogramming from either the mainline or the programming track.

Programmable activation - AD4 outputs can be set to flash, pulse or continuous on. The outputs can be connected to via a terminal strip, edge-card socket or direct soldering.

Easy Hookup With Optional Edge Connector - The AD4 slips into a 22 pin or a 44 pin edge card connector to allow easy connection to all of the AD4's functions. The connector features easy-to-use gold plated card fingers for reliable connections. The terminals are gold plated for easy soldering.
