FAQ
How do I choose between the three models?
ZSD-10003-R is the basic version with electrical parameters and temperature measurement; ZSD-11113-R adds 1 analog output and 1DI/1DO; ZSD-14463-R is the full version with 4 analog outputs and 4DI/6DO.
Which protocol and data formats are supported?
The meter uses MODBUS-RTU with function codes 01/02/03/04/05/06/0F/10H and outputs both float and integer formats. Baud rate is selectable from 1200 to 38400bps, 9600 by default.
How is temperature measurement connected?
On models with the temperature function, sensors are wired to terminals T1~T4. Model 1 in this range is supplied with temperature measurement, and temperature is shown and uploaded with the electrical parameters.
What wiring options and address range apply?
Both three-phase four-wire and three-phase three-wire connection are supported. Addresses run from 1 to 247, with a maximum of 32 meters on each RS485 bus.
What certification applies and how is pricing provided?
Certification is held through a CE / CMA / CNAS accredited laboratory. Price is quoted per model and I/O configuration; Request a quote with the model code and the number of analog outputs needed.
