Description
Functional Features
High-precision Measurement: It can precisely measure the frequency, period, and pulse width with a reading accuracy of ±0.001%. It can accurately monitor the pulse generating equipment and provide calculated rates and cumulative totals.
Multi-channel Design: It has 8 single-pulse or 4 double-pulse input channels, and can support single and double-pulse inputs to meet different measurement requirements.
Isolation Protection: The input is designed with high impedance, differential voltage, and optical isolation (1000VDC), which can effectively prevent external interference and ensure accurate signal transmission.
Flexible Configuration: The input edge can be configured to be triggered by the rising edge or the falling edge, and the rising edge is the default. Each channel can be selected for isolation or bus configuration through jumpers.
Output Function: It has 2 output channels, and the output type is an optically isolated solid-state relay (1500VRMS) with a replaceable fuse (2.5A). It has a fast cut-off function and can stop the operation when the threshold is reached, with a maximum delay time of 1ms.
Self-check Function: It has a complete self-diagnosis function, which can promptly detect its own faults, facilitating maintenance and management.
Technical Parameters
Input Frequency Range: For single channels, it is 0 to 100kHz, and for double-pulse channels, it is 0 to 10kHz.
Input Voltage Range: It is 0 to 35VDC, and it is independent of the input voltage range.
Input Impedance: Greater than 70kΩ.
Minimum Pulse Width: When the pulse width suppression is off, it is 3μs, and when it is on, it is 20μs.
Output Characteristics: The output voltage is 5V to 60VDC, the current is 0.001A to 2A, and the off-state leakage is a maximum of 100μA at 60VDC.

It is commonly used in metering and trade handover applications, supports the Meter Suite trade handover application and the ISO 6551/API 5.5 standard, and is suitable for industrial automation scenarios that require high-precision pulse measurement and control, such as flow measurement and rotational speed monitoring in industries such as chemical engineering, petroleum, and power.
Common Faults and Solutions Abnormal Input Signals Reasons: Sensor failures, connection cable problems, damaged input channels, incorrect parameter settings. Solutions: Check whether the sensor is working properly and replace it if it is damaged; check whether the connection cable has open circuits, short circuits, or poor contacts, and repair or replace the cable; check the input channel and contact a professional for repair or replace the module if it is damaged; confirm whether the parameter settings are correct, such as the selection of the input edge and the pulse width suppression, and reset the correct parameters. Output Faults Reasons: Damaged output relays, load problems, power supply failures. Solutions: Check whether the output relay has signs of damage and replace it if there are any; check whether the load is overloaded or short-circuited and eliminate the load fault; check whether the power supply is normal to ensure a stable power supply for the output channel. Communication Problems Reasons: Incorrect communication protocol settings, network connection failures, faults in the module communication interface. Solutions: Confirm whether the communication protocol settings are consistent with the system and reset them; check whether the network connection is normal and repair the network fault; check the module communication interface and repair or replace it if it is damaged.
