The TR400 is a full logic control process ratemeter that can display any production rate or time in process easily and accurately. The ability to accurately detect and convert 0.01 to 10,000 Hz signal input makes the TR400 an inexpensive solution to many industrial applications. With the addition of optional relay outputs and/or 4-20 mA analog output, the TR400 becomes a complete process control and display system. The optional relay outputs can be programmed for underspeed or overspeed, and include adjustable delays at "power up" and output activation. The 4-20 mA output can be scaled to reflect any area of the monitored range, including operations requiring an inverse output. Quadrature signal decoding gives the TR400 the ability to detect direction as well as speed for bidirectional applications. The relays and 4-20mA outputs can be programmed in the reverse direction as well as the forward direction, or both directions.

The standard TR400 system is supplied with a shaft-mounted magnetic pulser disc or optional pulser wrap, which generates eight pulses per revolution with our standard non-contact sensor. The sensor transmits the speed as a digital pulse frequency to the TR400 via a three-conductor shielded cable. The TR400 then compares this frequency signal to its programmed values to determine the appropriate display value and output states (if required). When the TR400 is programmed to detect quadrature input signals, the front panel will indicate the reverse direction with the "REV" LED. All outputs are fully functional in both forward and reverse directions. The relay outputs can be programmed to latch (requiring a manual reset), or stay active only when the set point condition is present. The TR400 set point delay allows the user to program how long the set point must be exceeded before the setpoint output activates.
