During the continuous casting and hot rolling phases in steel mills, this analog bus terminal connects field sensors to the central control system without interrupting the data stream. Installed in the control cabinets of strand guide segments, it collects temperature, pressure, and position signals from hydraulic cylinders and pinch rollers, then forwards them to the PLC. The terminal’s modular design allows it to sit directly on the bus rail alongside other I/O modules, reducing wiring complexity in environments where space is tight and vibration is constant. In reheat furnaces, it interfaces with thermocouples and gas flow meters, ensuring real-time adjustments to combustion parameters. Maintenance crews rely on its plug-and-play replacement to minimize downtime during roll changes or sensor recalibration. A secondary application appears in electrical substations serving steel plants, where it relays analog readings from transformer tap changers and circuit breakers to the plant-wide monitoring network.
