Product Introduction
The HART protocol uses the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on a 4 to 20 mA basis, allowing the HART protocol instrument to allow bidirectional data communication without interfering with the 4 to 20 mA analog signal. SM100-M series HART data collector is an intelligent converter for bidirectional modulation and demodulation of digital signal and analog signal.
Frequently Asked Questions (FAQ)
How many HART devices can the collector support simultaneously?
The SM100-M series HART data collector supports the connection of up to 32 HART devices at the same time, with parallel and simultaneous scanning across all configured channels.
Does the collector affect the 4 to 20 mA analog signal transmission?
No, the equipment does not affect the transmission and accuracy of the 4 to 20 mA analog signal under normal operation, power failure, or fault conditions.
What is the isolation voltage level of the interfaces?
The electromagnetic isolation voltage between the HART channels, as well as the RS485 and NET Ethernet interfaces, is designed to be not lower than 1500 V.
Does this data collector supply power to field instruments?
No, this equipment does not supply power to field instruments. Separate power sources must be provided for the field devices.
What mounting options are supported by the device?
The SM100-M series HART data collector supports standard DIN rail mounting, making it easy to install in industrial control cabinets.
Which versions of the HART protocol is this device compatible with?
It is fully compatible with HART protocol Version 5.0 and above.
