Overview
The TR400 is a logic control process ratemeter designed to display production rates or time in process with high accuracy. It can handle signal inputs ranging from 0.01 to 10,000 Hz, making it suitable for various industrial applications. Optional features include relay outputs and a 4-20 mA analog output, enhancing its functionality as a process control and display system.

Specifications

• Power: 115 Vac, with options for 230 Vac or 10-30 Vdc.
• Sensor Input: Switch selectable, with a maximum frequency of 4,000 Hz (10KHz available on request) and a minimum frequency of 0.01 Hz.
• Outputs: Optional 0-10 Vdc or 4-20 mA analog output, and 2 or 6 programmable form C relays rated at 250 Vac, 30 Vdc 5 A.
• Display: 4-digit, 0.3” height, seven-segment displays with five status LEDs.
• Operating Temperature: 0° C to +50° C (+32° F to +122° F).
• Dimensions: 3.1"W x 4.85"H x 6.25"L.

Principle of Operation
The TR400 uses a shaft-mounted magnetic pulser disc or optional pulser wrap to generate pulses, which are transmitted as digital pulse frequencies to the TR400. It compares these frequencies to programmed values to determine display values and output states. The device can detect direction and speed for bidirectional applications, with relay outputs programmable for various conditions.

Installation and Calibration
The TR400 is designed for easy installation and setup, with straightforward calibration processes. It includes security code lockout protection and non-volatile memory to retain settings during power outages. Assistance is available through tech support or downloadable manuals.

Sensor Installation
Sensors are supplied with mounting brackets and should be installed so that the center line of the magnets passes in front of the sensor's center line. Proper gap distance is crucial and can be adjusted using jam nuts or mounting bracket slots.
