8I5B Product Overview and Core Functions
8I5B adopts a modular design and supports multiple input signal types, suitable for measurement and display of process parameters such as temperature, pressure, and flow. Its core functions cover three major directions: high-precision acquisition, alarm output, and communication networking.
- Input types: Supports thermocouples, RTDs, standard current/voltage signals
- Display mode: Dual-row four-digit LED digital tube, real-time display of measured value and set value
- Output configuration: Relay alarm output, analog transmission output, RS485 communication
- Power supply: Wide voltage range AC/DC 85~265V, adapting to complex industrial sites

8I5B Installation and Wiring Steps
Correct installation and wiring are prerequisites for ensuring stable operation of 8I5B. Please follow the steps below and strictly refer to the terminal definitions in the 8I5B Chinese manual.
- Panel cutout installation: Cut a 92mm×45mm square hole on the control panel, push the instrument from the front of the panel, and secure with clips.
- Power wiring: Connect AC/DC 85~265V power to the designated terminals of the instrument, paying attention to polarity and grounding.
- Input wiring: Select corresponding terminals according to the sensor type. Thermocouples require compensation wires, and RTDs are recommended to use three-wire connection.
- Output wiring: Connect relay output to the load, transmission output to PLC or recorder, and RS485 using shielded twisted pair.
- Power-on check: After confirming correct wiring, power on, observe whether the display is normal, and perform parameter settings.
8I5B Parameter Setting and Commissioning Points
8I5B supports parameter configuration via panel keys. During commissioning, focus on parameters such as input type, range upper/lower limits, alarm values, and communication address.
- Input type setting: Must match the actual sensor, otherwise display abnormalities will occur
- Range setting: Set the display range according to process requirements to ensure linear correspondence
- Alarm mode: Can be set to upper limit, lower limit, or upper/lower limit alarm to avoid false triggering
- Communication commissioning: Confirm that baud rate, data bits, and parity bits match the host computer
8I5B Common Faults and Handling
During on-site use, 8I5B may experience abnormal display or output misoperation. The following are common faults and troubleshooting methods. For more details, please refer to the 8I5B Chinese manual.
| Fault Phenomenon | Possible Cause | Handling Method |
|---|---|---|
| Display shows "HH" or "LL" | Input signal over-range or sensor open circuit | Check sensor and wiring, reset range |
| Display value fluctuates greatly | Signal line interference or poor grounding | Use shielded wire, single-point grounding, keep away from power cables |
| Relay does not operate | Incorrect alarm value setting or damaged contact | Check alarm settings, test contacts with multimeter |
| Communication failure | Address conflict or wiring error | Check address, baud rate, and A/B line polarity |
8I5B Selection and Procurement Suggestions
When purchasing 8I5B, clarify the input signal type, output configuration, power supply mode, and communication requirements. It is recommended to request the latest version of the 8I5B Chinese manual from the supplier to confirm terminal definitions and parameter codes.
- Clarify signal type: Thermocouple, RTD, or standard signal, which determines the instrument model suffix
- Confirm output requirements: Whether alarm, transmission, or communication functions are needed
- Verify power supply voltage: Whether the on-site power is AC220V or DC24V
- Request certification documents: Such as CE, RoHS, etc., to meet project compliance requirements
Through the above points, engineering technicians and procurement personnel can quickly complete the selection, installation, and commissioning of 8I5B, ensuring stable and reliable industrial process control.
