Technical Specifications

Rack backplane power supply, standard full-height card structure

Dual-channel independent acquisition circuits, compatible with conventional eddy current probes

Stable measurement accuracy, frequency response covers the normal monitoring range of the equipment

Built-in alarm relay, supports 4-20mA analog output

Operating temperature 0℃ - 60℃, storage temperature - 40℃ - 85℃, shockproof, dustproof, anti-interference

Installation and wiring

Insert the card into the rack slot and lock it to ensure a tight connection of the bus

Connect the sensing cables to the corresponding ports for each channel, with strong and weak lines routed separately

Connect the alarm and signal output lines in a standardized manner, secure the terminals without loose connections

After checking that the wiring is correct, power on for debugging and configuration of parameters

Maintenance and care

Regularly check the operation indicator lights, observe that the values are stable without abnormal fluctuations

Regularly tighten the wiring terminals, check the integrity and cleanliness of the cables

Regularly calibrate the accuracy, test the response effect of alarm triggering

Reduce frequent plugging and unplugging, store the spare modules in a dry and ventilated environment Fault diagnosis

The channel has no data. Check the power supply, slot contact and circuit continuity.

The numerical fluctuations deviate. Adjust the probe gap and optimize the shielding grounding treatment.

The alarm action is abnormal. Verify the threshold setting and detect the relay contacts.

The signal transmission is abnormal. Check the wiring and recheck the module configuration parameters.
