Digitrax PM74 Power Manager With Occupancy and Transponding Detection for 4 Sub-Districts

Get the benefits of short circuit management and auto reversing without adding more boosters! The PM74 Power Manager lets you use a single booster and divide its output into 4 power sub-districts for automatic reversing or to improve operation by preempting booster shutdown when a short circuit is detected by the PM74. If you want to improve operation but don't need the added power (or expense) of adding a booster, the PM74 is the right answer for you. Each PM74 can run 4 sub-districts off a single booster in any combination of regular sub-districts and auto reversing sub-districts.

PM74 Features:

• Upgraded replacement for PM42, fully encased.
• 4 Power manager sub-districts (or DS sections), similar to PM42.
• Each DS section configurable for Auto-reverse or intelligent short-circuit Power Management function.
• Each DS has Occupancy and Transponding detection capability.
• Occupancy usable by LocoNet compatible signal systems and e.g. PCbased track state monitoring.
• Transponding provides mobile decoder Mainline Operations Mode CV read/write programming on compatible Digitrax systems.
• Transponding identifies compatible Decoder addresses in each DS.
• All plug-in connectors for simple and easy installation and service.
• User defined as 4 DS reporting addresses in 2000+ DS range.
• Low-loss magnetic sensing of DCC track current.
• Easy setup with device Option Switches (OPSW) or LocoNet CV programming.

• Configured to operate with DCS52, DCS100, DCS210, DCS210+, DCS240 Command Stations, and DB210 and DB220 boosters.
• Optional Detection and Power status led connector for remote state indication, compatible with e.g. LT5.
