40 TB is a 2-channel alarm device based on microprocessor, format 96x96 (1/4 DIN), made by SMT.Its operating interface is comprehensive and efficient, and two process variables and engineering units display two 4-digit displays.It is also equipped with a red LED bar chart that can be associated with process variables and peak values.Three leds display the output state, and three leds can be configured to represent different functional conditions.The instrument has a lexan membrane panel (guaranteed IP65) with four keys.Channel 1 has a strain gauge, pressure or force sensor input, with positive or symmetrical polarization rate, calibration sensitivity automatically calculated (from 1, 5 to 4 mV/V), indicating that the detector power is interrupted.The first input channel also receives a potentiometer signal from a 100 ohm resistor.

The performance of A/D converters can be configured through the keyboard, so different sampling time options can be selected according to the required resolution.The sampling time can be as low as 15 seconds.The resolution can reach the maximum.The value of 16, 000 divisions.Sampling time.The second input channel can be configured for input from temperature sensors (TC, RTD, PTC, NTC) and mV, V, mA signal, and capable of customizing input for each sensor.You can select different options from the keyboard.There are likely to be two digital inputs ranging from voltage free contact to functions such as reset, hold, flash, peak or memory reset control.These instruments can be equipped with up to three relay (5A / 250V) or static (0-11vdc) output.Two voltage or current analog output can be used for retransmission of input, alarm device, gross weight and weight.Serial communication options may have the current loop, rs422/485 and RS232 connect baud rates up to 19,200.Each input channel can anticipate the "transmitter power" selection.Channel 1 could be: 1V (potentiometer), 5 and 10V (strain gauge), 15 and 24V;Channel 2:15 and 24 VDC.By grouping the parameters in the block and the simplified data entry menu, it becomes easier to program the tool.The configuration can be further simplified using the PC programming toolkit that contains the cable and the menu wizard that runs under Windows (see the technical data code 80020).Configurable personal software protection code (password protection) can be used to limit the level of editing and display configuration parameters
