1747-SN

The 1747-SN remote I/O scanner module by Allen Bradley is an essential component in the SLC 500 series. This module is designed to facilitate connections between I/O adapters and controllers, enhancing the flexibility of distributed controller applications. The ability to operate in both normal and complementary modes adds versatility, allowing one to connect up to 16 devices in normal mode and up to 32 devices in complementary mode, depending on system requirements.

This unit supports an extensive RIO cable length of 3050 meters, which can be beneficial in large-scale implementations where I/O devices are positioned at significant distances from the controller. Noise immunity is also integrated into the design, ensuring stability and reliability in environments prone to electrical noise. The backplane current draw at 5 volts is measured at 600 mA, indicating moderate power requirements for operation.

In terms of operating conditions, the 1747-SN module works effectively within a temperature range of 0 to 40 degrees Celsius while tolerating storage temperatures up to 50 degrees Celsius. Additionally, it can function at altitudes of up to 1000 meters above sea level, enabling usage in various geographical locations. The combination of these features makes the 1747-SN a reliable choice for enhancing input/output capabilities in industrial automation systems.
