THM502-I and THM602-I - New head-mounted transmitters with Modbus RTU output


Official product release of the new THM502-I and THM602-I temperature transmitters equipped with Modbus RTU output and galvanic isolation.

Temperature is a key indicator in many industrial processes. Based on this principle, Tekon Electronics has developed two new head-mounted transmitters focused on acquiring the signal from various types of sensors (RTD, thermocouples, linear resistances and linear voltages) with signal output in Modbus RTU, a protocol widely used in the industry. .

With these new equipment, the number of temperature monitoring/measurement solutions for process installation with Modbus RTU output are now three. The new transmitters THM502-I and THM602-I are an evolution of THM501-I transmitter with Modbus RTU output and are distinguished by the type of sensors supported as well as improvements in measurement accuracy and EMC performance.

Interface for quick diagnostic and configuration

The new transmitters are designed to simplify commissioning, on-site diagnostics and maintenance. The interface incorporates operational status diagnostic LEDs that provide communications and sensor status information. It also incorporates a button to enter configuration mode, without the need to restart the equipment.
