203 series of intelligent frequency meter/tachometer is suitable for speed, line speed and frequency measurement. Microprocessor is used for control operation. The intelligent frequency meter/tachometer can freely convert the input frequency to a wide range of scales (such as speed, linear speed, etc.). Low functional features multiple protection, isolation design, strong anti-jamming capability, high reliability, good software platform, the secondary development ability, in order to meet the special functional requirements with the calibration, calibration and perfect the function of the sensor fixed network communication function, and all kinds of belt two-way communication serial input/output equipment, main technical index of network control system is low basic error: 0.5% FS or 0.2% FS + 1 word display way: double row four digital tube LED display or single row six LED digital tube display sampling period: 0.2 S input signals: Analog 1-5v or 4-20ma two-line pulse, TTL pulse, NPN, PNP voltage pulse measurement range: 0.1 ~ 9999HZ

Alarm output: second limit or fourth limit, alarm mode and alarm sensitivity can be set, relay output contact capacity AC220V/3A or AC220V/1A. Communication output: interface mode -- isolated serial two-way communication interface RS485/RS422/RS232/Modem baud rate --300 ~ 9600bps internal setting transmission output: 4 ~ 20mA, 0 ~ 10mA, 1 ~ 5V, 0 ~ 5V precision: ± 0.3% FS feed output: DC24V/30mA power source: switching power supply 85 ~ 265VAC power consumption 4W

Model example: 203CB2X1V24M3 203 series intelligent frequency meter/tachometer, TTL pulse signal input, external size 96×48×110mm, 2 relays control output, with 4 ~ 20mA transformer output, with DC24V feed output, power supply 220VAC.
