Frequently Asked Questions (FAQ)
What are the signal conversion capabilities of the SM626H-DA?
The SM626H-DA is designed to collect 2 channels of 4-20mA input signals and convert them into 1 channel of 4-20mA output and 1 channel of RS485 communication.
Do I need to reconfigure the module after a power failure?
No. The device features a built-in power-off memory function, which ensures that all configuration parameters are retained and do not need to be reset after power is restored.
What type of A/D sampling does the device use?
The collector features two analog acquisition channels with 16-bit high-precision A/D simultaneous sampling functionality.
What are the power and environmental requirements?
It requires a DC 24V power input. The operating temperature range is -20 ℃ to + 80 ℃, and it works within a relative humidity range of 10% to 80%.
How can I monitor the working status of the collector?
The integrated communication transceiver indicator provides a clear visual signal of the collector's current operating and communication status.
