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 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 4-20 mA outputs can be programmed in the reverse direction as well as the forward direction, or both directions.
