ABB UAC318AE HIEE300744R1｜Control Module｜

core functionality
Connect ABB Presductor pressure magnetic tension sensor and provide sensor excitation power supply;
Hardware level high-speed tension signal acquisition, filtering, and operation, outputting tension 4-20mA analog quantity;
Equipped with DI/DO digital contacts to achieve tension over limit alarm and interlock protection;
Communication: RS232 debugging port, connected to transmission controller (DCS/AC800M);
Working temperature: -20 ℃~+60 ℃, cage rack installation;
Accuracy: Suitable for 2-3mV/V pressure magnetic sensors, with high tension measurement accuracy and fast response, suitable for high-speed coil winding and unwinding processes.
Typical Engineering Application Cases
Case 1 | Cold rolled steel strip production line (unwinding coiling tension closed loop)
System: ABB AC800M transmission+UAC318AE tension plate;
Location: Acid pickling cold rolling mill, inlet uncoiler, intermediate frame, outlet coiler;
Configuration: Each tension roller is equipped with one UAC318AE+Presductor pillow sensor; Calculate the actual tension locally on the board and provide 4-20mA to the transmission system for tension closed-loop;
Value: prevent strip breakage and deviation, ensure uniform thickness of thin strip during rolling; A large number of old cold rolling lines are in use domestically, and there is a high demand for spare parts replacement.
Case 2 | Aluminum foil and copper foil rolling production line (non-ferrous metal rolling mill)
Working condition: Extremely thin foil material, with low tension but strict control requirements. Even small fluctuations in tension can cause the foil to break;
Usage: UAC318AE collects tension roller pressure magnetic sensor, hardware fast processing, does not occupy the CPU load of the main controller; The tension exceeds the limit and the hard contact directly triggers the emergency stop interlock;
Benefit: Reduce the scrap rate of foil strip breakage, suitable for aluminum foil and copper foil rolling mill renovation projects.
Case 3 | Paper Machine and BOPET Film Production Line
Scenario: Paper machine rewinding section, plastic film biaxial stretching production line;
Solution: Multiple tension rollers, UAC318AE processing of tension in each section, signal transmission to DCS, achieving segmented control of tension in the entire line; The sudden change in paper/film breakage tension immediately triggers an alarm interlock, reducing waste and downtime.
