ABB TMD-T4S Temperature Control Unit PT100 Modbus RS485
it is a temperature control and monitoring unit designed for protection and supervision of transformers, motors, and industrial machines. It measures temperature via RTD PT100 sensors and provides front-panel digital indication for values, alarms, and operating status.
It supports four PT100 inputs and provides intervention levels such as Alarm and Trip for warnings or controlled shutdown. Relay outputs are available for alarm, trip, fault, and fan control. The version adds RS485 Modbus-RTU communication and a programmable 0/4-20mA analog output for integration with PLC, SCADA, and monitoring systems.
Commonly used in transformer protection panels, motor monitoring, cooling fan control, electrical rooms, and automation systems requiring reliable temperature supervision with Modbus connectivity.
