Product Description:
The 3UM161.6 module is present in the System 2005 Controllers range offered by B & R Automation where it functions as a current monitoring relay for accurate load supervision. It employs a type of current monitoring relay which allows detecting the deviations of current accurately. The device gives 1 CO changeover, 1 NC normally closed contacts configuration those assist in alarm as well as safety circuits concurrently. It further runs on an AC 24 V source voltage, this conforms with typical control-panel voltages without additional transformers.
The controller type covers a measuring range from 2 A to 20 A which accommodates both small and mid-sized motor loads. It carries an AC-15 contact rating of 230 V at 3 A and that ensures safe switching of control circuits. It also employs AgCdO output contact material to resist welding and guarantee long service life. The component functions between –20 °C and +60 °C which suits typical factory environments. It mounts on a DIN rail and simplifies panel assembly. It includes IP20 enclosure protection to block solid objects above 12 mm and prevents accidental touch. The gadget resets within ≤ 200 ms and allows support for a rapid fault cycling and minimizes downtime.
B & R’s 3UM161.6 releases contacts in ≤ 50 ms, preventing extended fault conditions and protects downstream equipment. It runs at 50 Hz or 60 Hz frequency in order to match global power standards. The device within a plastic housing material provides insulation and reduces weight. It uses a source output circuit type for supplying positive switching outputs and simplifies wiring polarity. Moreover, the controller features thermal-shutdown output protection which disables outputs during overloads and prevents module damage. Further, it maintains nominal output currents from 10 mA up to 2 A and enables compatibility with diverse control devices.
Frequently Asked Questions about 3UM161.6:
Q: How many contacts does the 3UM161.6 provide?
