Frequently Asked Questions

QWhat communication interfaces and protocols does the SM100-G support?

The SM100-G is equipped with an RS485 communication interface that supports standard MODBUS and RTU protocols. It operates independently of the HART bus's 1200 communication speed to increase system processing velocity.

QCan the SM100-G output multiple signals simultaneously?

Yes, the SM100-G is designed to collect HART protocol data and output 4-20mA current and RS485 signals simultaneously, along with DO relay outputs configured with 2 or 4 channels.

QWhat are the power supply requirements for this controller?

The device requires a power supply input voltage of DC 12 ~ 24 V, with a working current of 100mA. The ripple of the power supply must not exceed 200 mA.

QWill the controller lose its settings during a power failure?

No, the controller features a built-in power-off memory function. This ensures all parameters are saved and eliminates the need to reset configuration values when power is restored.

QHow is the SM100-G controller installed?

The SM100-G is housed in an industrial universal module shell that simplifies commissioning. It supports two installation methods: fixed installation or standard rail mounting.
