The SM626H-A features four-way analog acquisition with 16-bit high-precision A/D simultaneous sampling, plus two-channel pulse counting and switching value sampling.
Yes, it includes a dedicated DC 24V output with 20 mA drive capability specifically designed to power two-wire sensors.
It supports the MODBUS_RTU protocol via RS485, and offers data transmission through UDP or TCP modes, compatible with fixed IPs and dynamic domain names.
Absolutely. It has a power-off memory function for parameters and an internal EEPROM that saves data every minute, storing historical records for up to one month.
Parameters such as station number, timing, and alarm thresholds can be queried and set both locally via the USB interface and remotely via the communication network.
The device is rated at IP65 protection class, making it suitable for industrial environments with an operating temperature range of -20 ℃ to +80 ℃.
