Please check the part number of label on the products carefully before use.

Make sure to connect the inputs, outputs and power supply correctly and properly before power on. The power supply, input signal and the output signal (for treble isolation products) cannot be commonly grounded.

The voltage of power supply must be in conformity with that shown on the label of the product. Its accuracy can not be under 5%, ripple should be ≤0.4%. It is highly suggested that you had better connect its common output to the earth.

Generally, the load resistance of output of transducers with current output must not be more than 250Ω, and long term open circuit output are not allowed. For transducers with voltage output or frequency output, their output load resistance must be ≥2KΩ. When they are powered on. Their output load resistance can not be <<2KΩ, and short circuit output is not allowed. Their output load must be passive device.

For more precise measurement, it is suggested that you can do it by using an instrument with higher accuracy after all circuits and the transducers have been powered on for 15 minutes. Please ensure that the terminal screws are tightened securely and reliably before measuring directly on output terminals of transducer with probes of meter.

When more than one transducer are mounted together, please keep a space more than 10mm between adjacent units. 35mm (width) DIN rail mounting and M3 screws for surface mounting are available optionally.

The damage of power supply is usually caused by improper use. If the transducers and other device with interference (such as relay) use one power supply commonly, the pulse interference may damage the power supply.

The small-signal transducers mean those whose AC voltage input is ≤10V or AC/DC current input is ≤ 2A or DC voltage input is ≤1V. They should be installed far away from strong electromagnetic interference and cannot use one power supply commonly with electromagnetic valve, circuit breaker or relay. The signal wires of small-signal transducers cannot be trussed together with the devices with strong electromagnetic interference to make sure the small-signal transducers operate stably.

The damages of the output terminals are usually caused by strong interference. The wiring design should be arranged carefully. If signal wires of transducers are in line with the power cord of power unit, the strong spurious noise may damage the output of transducer.
