The module allows for direct connection of two thermocouples. Operation of grounded sensors is possible due to internal galvanic separation. The module automatically linearizes the full temperature range. Error compensation in the ambient temperature range of 0 °C - 55 °C is implemented in the module by compensating for cold ends. An interruption of the input circuit is indicated by a red LED. The green LED indicates the readiness of the device and no interference in communication with the network interface. The screen is connected directly to the mounting rail.
