The Transyt LMD 40 Traffic Controller is the remaining pre-timed, interval-based traffic controller offered by Peek. It is still being used to control intersections in various cities in North America, and has proven through long service to be a reliable and robust choice for those who wish to remain with pre-timed intersection timing. They continue to be manufactured in Peek's Palmetto manufacturing facility.

The LMD 40 is a stand alone, shelf mounted unit with a fold down front panel and removable EEPROM card for data memory. The LMD 40 utilizes a backlit, 4 X 40 character liquid crystal display operated in a menu format.

Features

• The LMD40 controller unit provides menu driven, solid state pretimed and/or actuated control of 48 circuits
• Thirty-two intervals are available to define the on/off condition of each circuit
• The unit can be programmed for a variety of sequences, either pretimed or actuated, 2-8 phase operation
• Ten actuation inputs are available to allow phases to be programmed as both callable and extendible, without switching signal plans
• Unused actuation time can be added to a selected interval to maintain the cycle length during coordination
• The added time feature can be inhibited by time clock so that during off-peak hours the LMD 40 can operate in a variable cycle length mode based on actual demand. In this mode, the unit can be set up to rest at the end of main street green, where it will respond immediately to side street demand.
• Signal sequence information, referred to as the signal plan, is customized to the specific intersection application.
• The LMD 40 can store 8 unique signal plans and 5 pre-emption sequences.
• All data is programmed via the front panel keyboard, including signal plans configuration.
• Two security codes are available, one for signal plan programming, and one for timing data.
• Internal time clock and coordination are standard features and require no special modules or added circuitry.
