major function

●Analog input:
8 channels with voltage ranging from 0 to 250V. The input signal is DC or AC (frequency 25-75Hz).
The range options are: 100mV, 200mV, 500mV, 1V, 2V, 5V, 10V, 20V, 60V, 100V, 200V, 250V Or 8 channels of 0-20mA current. The input signal is DC or AC (frequency 25-75Hz).
The range options are: 1mA, 10mA, 20mA, 100mA, 200mA.
Signal processing: 16 bit A/D sampling; Sampling rate: 3000 samples per second. Output true valid value.
Measurement cycle: 0.2 seconds per channel, 8-channel cyclic measurement.
Overload capacity: 1.2 times the range can be measured correctly; Overload twice the range input for 1 second without damage.
●Frequency measurement and counting input:
Two independent optoelectronic isolation inputs; Simultaneously measure and count the frequency of the input signal;
When applied to counting: pulse width>100 uS, signal high level 5V -30V. Maximum count value: FFFFFFFFH。
2-channel pulse counting input can be set to power down storage or power down no storage; The count value is not stored after power failure, and accumulates from 0 after power on; The count value is stored during power failure, and the count value during power failure is stored in EEPROM. After power on, it accumulates from the value before power failure.
When used for frequency measurement: the frequency range is 0.1Hz to -3 KHz, and the input voltage range is 5-30V.
●Isolation: Isolation between analog signal input, frequency measurement and counting input, and communication interface output, with an isolation voltage of 1000V DC. SLT, DATA+, DATA -, VCC, GND are output terminals and are grounded together with the GND terminal; The common ground terminal for the 8-channel measurement signal input is the AGND terminal;
●Communication output
Interface: RS-485 interface, two-wire system, ± 15KV ESD protection.
Protocol: Dual protocol: ASCII code protocol and hexadecimal LC-04 protocol. Choose between suspended or grounded by SLT.
Speed: 1200, 2400, 4800, 9600, 19200 Bps, software adjustable.
Module address: 00~FF can be set by software.
