Note

1. Resistive Load: The maximum value of all parameters of the relay is realized when the load is resistive load. Resistive load means the load that iodine tungsten lamp, incandescent lamp, resistance furnace, oven, electric water heater, etc. will not cause voltage and current phase changes.

2. Contact Maximum Switching Voltage: this value is the maximum value when the load is a resistive load, and supports DC and AC voltage. If the load is a capacitive load or an inductive load, this indicator may be reduced.

3. Data Communication Rate: This parameter refers to the communication speed between the MCU controller and the host computer, which belongs to the theoretical maximum value. The communication rate will also be affected by the length of the field wiring, the number of loaded modules, the programming architecture of the host computer, and the hardware capabilities of the CPU.
