XV-102-B4-35TQR-10 Technical Parameters & Troubleshooting Methods
1. Technical Parameters
1.1 Brand & Model Information
Brand: Moeller (a key brand of Eaton Group, focusing on industrial automation control products). Model: XV-102-B4-35TQR-10. Product Category: Industrial-grade PLC (Programmable Logic Controller) with integrated control functions, suitable for medium and small-sized automation systems.
The XV-102-B6-35TQR-10-PLC adopts a dual-power design, including main power supply and auxiliary power supply. For the main power supply, connect the AC 220V power source to the L and N terminals on the PLC power module (terminal numbers: L1, N1). Ensure the voltage fluctuation range is within ±10% to avoid abnormal operation caused by voltage instability. For the auxiliary power supply, which is used to power external sensors and input/output components, connect the DC 24V power supply to the +24V and 0V terminals (terminal numbers: DC+, DC-). It should be noted that the positive and negative poles must not be reversed during wiring; otherwise, the internal circuit of the PLC may be damaged.
1.2 Core Electrical Parameters
Power Supply: AC 220V ±10%, 50/60Hz. Power Consumption: ≤30W (no-load condition). Operating Temperature Range: 0°C ~ 55°C. Storage Temperature Range: -20°C ~ 65°C. Relative Humidity: 10% ~ 90% (non-condensing). Protection Level: IP20 (panel-mounted), suitable for indoor industrial environments.
The XV-102-B6-35TQR-10-PLC is equipped with multiple digital input terminals (labeled as I0.0, I0.1, …, I3.7) and analog input terminals (labeled as AI0, AI1). For digital input wiring (e.g., connecting photoelectric sensors, limit switches), adopt the sinking or sourcing input mode according to the sensor type. In the sinking mode, connect the sensor’s signal output terminal to the digital input terminal, and the sensor’s common terminal to the +24V terminal of the auxiliary power supply. In the sourcing mode, connect the sensor’s signal output terminal to the digital input terminal, and the sensor’s common terminal to the 0V terminal. For analog input wiring (e.g., connecting pressure transmitters, temperature sensors), use shielded twisted-pair cables to reduce interference. Connect the signal positive pole of the sensor to the AI+ terminal, the signal negative pole to the AI- terminal, and the shield layer to the ground terminal of the PLC.

1.3 Input & Output Parameters
Digital Input: 16 channels, sinking/sourcing compatible, DC 24V. Analog Input: 4 channels, support 0~10V DC / 4~20mA current signal. Digital Output: 12 channels, relay output (AC 250V/5A, DC 30V/5A). Analog Output: 2 channels, 0~10V DC / 4~20mA optional. 1.4 Communication ParametersCommunication Interfaces: RS485, Ethernet (RJ45). Supported Protocols: Modbus RTU, TCP/IP. Communication Rate: RS485 up to 19200 bps; Ethernet up to 100Mbps. Maximum Connected Nodes: 32 nodes (via RS485); 254 nodes (via Ethernet).
2. Troubleshooting Methods
2.1 Power Supply Faults
Phenomenon 1: Power indicator (PWR) not lit. Causes: Power supply voltage abnormal, power cable loose or damaged, power module failure. Solutions: Check if AC 220V power supply is stable; inspect power cable connections and replace damaged cables; test power module output voltage, replace module if abnormal. Phenomenon 2: Power indicator flashes intermittently. Causes: Voltage fluctuation exceeds ±10%, poor contact of power terminals. Solutions: Install a voltage stabilizer; re-tighten power terminal screws to ensure reliable contact.
The PLC’s output terminals are divided into relay output (labeled as Q0.0, Q0.1, …, Q3.7) and transistor output (labeled as T0.0, T0.1, …, T1.7). For relay output wiring (suitable for driving AC/DC loads such as contactors, solenoid valves), connect one end of the load to the output terminal and the other end to the power supply (AC 220V or DC 24V). The common terminal of the relay output (labeled as COM1, COM2) should be connected to the corresponding power supply terminal. For transistor output wiring (suitable for high-frequency switching loads such as stepping motors), adopt the sinking output mode: connect the load’s positive pole to the +24V terminal, and the load’s negative pole to the transistor output terminal; the common terminal (COM) is connected to the 0V terminal. It is recommended to install a freewheeling diode (for DC loads) or a varistor (for AC loads) in parallel at both ends of the load to protect the PLC output circuit.
3.Communication Interface Wiring
The XV-102-B6-35TQR-10-PLC is equipped with RS485 and Ethernet communication interfaces for data interaction with upper computers, touch screens, or other PLCs. For RS485 communication wiring, use shielded twisted-pair cables. Connect the A terminal of the PLC’s RS485 interface to the A terminal of the external device, and the B terminal to the B terminal of the external device; the shield layer is grounded at one end to avoid signal interference. For Ethernet communication wiring, use Cat5e or above unshielded twisted-pair cables. Insert one end of the cable into the PLC’s Ethernet port (RJ45 interface) and the other end into the network port of the external device (such as a router, upper computer). Ensure the network cable is properly crimped to ensure stable data transmission.
3.1 Input/Output Terminal Faults
Phenomenon 1: Digital input signal not detected. Causes: Sensor power failure, input terminal wiring loose, input channel damaged. Solutions: Check sensor power supply; recheck input wiring connections; use a multimeter to test input channel voltage, isolate faulty channels and replace if necessary. Phenomenon 2: Digital output fails to drive load. Causes: Relay contact burnout, output terminal wiring disconnection, load overload. Solutions: Test relay contact continuity with a multimeter; rewire output terminals; check load current, ensure it does not exceed relay rated current, add a current limiter if needed.
3 Communication FaultsPhenomenon: Failed to communicate with upper computer/touch screen. Causes: Communication cable damaged, protocol parameter mismatch, IP address conflict (Ethernet). Solutions: Replace communication cable; confirm protocol type, baud rate, parity bit are consistent with external devices; reconfigure PLC IP address to avoid conflict.
4 Operation Faults Phenomenon 1: Program execution abnormal. Causes: Program logic error, memory corruption.
Solutions: Check and debug program logic; clear memory and re-download the program.
Phenomenon 2: PLC sudden shutdown. Causes: Over-temperature protection triggered, external electromagnetic interference.
Solutions: Check ventilation conditions to ensure no overheating; add shielding measures for signal cables, separate power lines and signal lines.
Before wiring, cut off all power supplies to prevent electric shock or circuit damage. Ensure the wire cross-sectional area matches the current capacity (recommended 1.5mm² for power lines, 0.75mm² for signal lines). All wiring terminals should be tightened to avoid poor contact caused by loose connections. Keep power lines and signal lines separate (at least 10cm apart) to prevent electromagnetic interference. After wiring, check the correctness of the wiring again (especially the positive and negative poles of the power supply and the connection of input/output signals) before powering on the PLC. For outdoor or harsh environment applications, take protective measures such as waterproofing, dustproofing, and anti-corrosion for the wiring.
