Product Intro

The TSD61XX series is a multi-channel temperature data logger that supports PT100 3-wire temperature sensors and uplink RS485 communication. It features fast acquisition response, high accuracy, and a large number of channels. Equipped with protection mechanisms such as channel open-circuit and short-circuit alarms, it ensures long-term stable operation, making it an ideal choice for multi-channel temperature acquisition and monitoring scenarios.

Product overview

The TSD6xxx is a multi-channel temperature data logger. It provides 4 to 24 temperature acquisition channels and supports PT100, NTC, and thermocouple sensors. Its RS485 serial port supports the standard Modbus RTU protocol, allowing up to 16 devices to be connected to the RS485 bus.

The temperature logger features an industrial-grade design and can operate stably in temperatures ranging from -20°C to 85°C. It features fast temperature response, accurate temperature acquisition, stable operation at high temperatures, and a wide range of acquisition channels. It also features open and short-circuit alarms for the acquisition channels, facilitating fault location and improving production efficiency.

Common faults

During device use, some faults may occur, and the user can restore the normal operation

of the device according to the faults and solutions listed below. If the problem cannot be solved,

please contact our after-sales service.

Power failure

Fault: the panel indicator lights are not lit after power-on.

Solution:

1. Check whether the power cable is connected and is in good contact with the terminal.

2. Check whether the positive and negative poles of the power cable are reversed.

3. Use a multi-meter to measure whether the input voltage is in the specified voltage range

(9~36V DC).

Communication failure

Fault: RS485 communication failure

Solution:

1. Check whether the device parameters are configured correctly.

2. Check that the indicator lights on device panel display correctly.

3. Check whether the communication wiring is correct, if yes, check whether the

communication parameters are configured correctly.

4. Check whether the address of the 485 dial switch is the same as the communication

address of the upper computer.

The collection temperature is abnormal

Fault: the collection temperature is abnormal

Solution:

1. Check whether the temperature sensor is wired correctly.

2. Check whether the terminal is tightened and not loose.

3. Check whether the temperature sensor is in good contact with the object under test.

4. Check whether the temperature sensor is supported by the collector.

5. Check whether the register address read by the upper computer is correct.
