A wide range of digital panel meters series mt4y and mt4w is offered by autonics corporation . These panel meters have some technical features which include: 4-digit red led type display and can be used to measure different electrical parameters. These panel meters can be used to measure ac voltage, dc voltage, ac current and dc current; power supply for the panel meters are 100-240 v ac 50/60 hz; digital panel meters are available only with indication without output or indication with output; outputs are relay with 4-20 ma, relay output, npn/pnp + bcd output, npn/pnp + 4-20 ma, npn/pnp + low speed serial output, npn/pnp + rs485 output, relay + rs485 output, etc. Maximum measuring inputs are 500 v ac/dc or 5 a dc/ac; and maximum display ranges are -1999 to +9999. Sampling time is 50 msec for dc and 16.6 msec for ac. The digital panel meters can be programmed for various functional by using the pushbuttons in front of the meter. These panel meters find their applications in electrical panel boards to display the voltage and current values. Also the output from these can be used to control the parameters in the power plants as a feedback to the dcs or plc; to display the electrical parameters; digital panel meters are also used.
