Temperature sensor input expansion module

An industrial temperature sensor input expansion module featuring four dedicated thermocouple input channels, designed for direct temperature monitoring and thermal loop control in compact PLC architectures. It operates by converting millivolt signals from Type K or Type J thermocouples into digitized high-resolution process data, transferring temperature values directly into the PLC memory via the expansion bus without requiring external signal converters. Built with cold-junction compensation, open-circuit burnout detection, and removable screw terminal blocks, it delivers precise, space-saving thermal regulation for heating zones, sealing machinery, and industrial oven automation systems.
