- Input types: thermocouple, RTD, standard current/voltage
- Output types: relay, SSR, 4-20mA
- Display mode: dual-row four-digit LED digital tube
- Power supply: AC/DC 85-265V or 24VDC
5L4C Selection Points
Selection by Signal Type
Select the corresponding input code according to the on-site sensor output signal to avoid measurement errors caused by signal mismatch.
- Thermocouple: K, S, B, E, J, T, N, etc.
- RTD: Pt100, Cu50, etc.
- Analog quantity: 0-10V, 4-20mA, etc.
Selection by Control Output
Select the output module according to the actuator type. Common ones include relay output, solid-state relay drive, and linear current output.

5L4C Installation and Commissioning Steps
Installation Steps
- Cut a 45×45mm square hole on the panel, insert the instrument, and secure the clips.
- Connect the power, input, and output lines according to the wiring diagram in the manual.
- After confirming the wiring is correct, power on; the instrument will self-check and display the measured value.
Parameter Setting Steps
- Long press the SET key to enter the parameter menu.
- Use the up and down keys to modify input type, range, alarm value, etc.
- Press the SET key to save and exit; the instrument returns to normal operation.
Common Issues and Precautions
- Abnormal display: Check whether the input signal exceeds the range or whether the wiring is loose.
- Control not working: Confirm that the output type matches the actuator and whether the alarm value is set correctly.
- Anti-interference: Use shielded cables for signal lines and keep them away from power lines.
