Propagation delay, ringing, or slow edges? Most likely signal integrity first, not counter propagation delay. At higher RPM: Faster pulse rate makes ringing/reflections more visible Long 20 cm trace can cause overshoot/undershoot Slow or noisy edges can violate logic thresholds Counter...

Sensors should be placed close to motors .... to get accurate measures ..... but keep the traces or wires short and routed away from high-current motor lines. For star grounding, it’s usually best to tie the motor ground to the logic ground at a single point near the motor drivers .... that way...

Yeah the wrong sensor readings are likely coz of the interference from the motors ..... especially when running at high speed. Even with 100 nF caps .... breadboards can’t isolate noise well. On the PCB, keep motor power traces thick and separate from sensor and Arduino logic traces. Place 0.1uF...

If your ABB REX640 works in Modbus Poll but not in PME, the problem is likely configuration, not hardware. First, check that the baud rate, parity, stop bits, and node address match exactly. PME needs the correct driver or device template to read registers. Sometimes, a custom Modbus device is...

Node-RED: “failed with result exit-code” usually means- The service can’t read its configuration files (permissions wrong) Or the Node-RED user directory (/home/pi/.node-red/) changed owner Or Node.js environment broke You can run these commands- sudo chown -R pi:pi /home/pi sudo usermod...

When a control valve is fitted with a spring-to-close actuator, it is designed to fail closed if air supply is lost. This means that without air pressure, the valve naturally moves to the closed position. In this setup, the electronic positioner is calibrated such that 4 mA fully opens the...

Visually inspect and clean the flame probe tip/insulator. Carbon build-up, soot, or condensation can block the flame signal. Check probe wiring and earth/ground continuity, since ionisation detection relies on a solid reference to ground. If the MPA22 provides a flame signal or microamp...

When troubleshooting intermittent PLC input signal loss, a methodical and structured approach goes a long way—much like the PCB diagnostic process highlighted in the PCBWay blog. You start with a visual inspection, looking for loose contacts, damaged wires, or signs of corrosion—very much like...

You can use permanent dew point sensors downstream of dryers and at critical control panels. Integrate with your SCADA/PLC system to log data and set alarms.

If you're planning maintenance on a Frame 6B, ask your parts supplier or GE service representative whether your turbine originally used the older 302A4010P002, and if so, whether the 328A8483P001 is offered as a direct upgrade. They can reference your serial number or turbine baseline to confirm...

Check Fuel Pressure. Low or high pressure can prevent proper atomization of the fuel. Use a pressure gauge at the inlet to confirm it matches the burner specifications.

Check PLC fault configuration to ensure a module fault doesn’t cause a major fault. Put the slot in inhibit mode from Studio 5000/RSLogix 5000 (if FlexLogix/CompactLogix/ControlLogix is used).

If possible, swap cables with another known working HMI to rule out cable or port failure.

Fast-acting control valves are critical. Industry preference is for high-performance globe valves or butterfly valves with low dead time and hysteresis. Use smart positioners (e.g., Fisher DVC6200, Siemens SIPART, ABB TZIDC) with diagnostics. Avoid valves with long stroke travel or large...

If you're okay with a bit of assembly but not building from scratch, you can use an ESP32 or a Raspberry Pi Pico + Analog Switches + DACs. Use analog switches (e.g., ADG733) to switch between real sensors and DAC (simulated value). You have to write the script in MicroPython or Arduino.

None of the modules you listed are direct replacements for the MTL5082, which is a specialized resistance signal isolator designed to interface directly with 2-, 3-, or 4-wire RTDs (e.g., Pt100) in hazardous areas. Most of your listed modules, such as the MTL7056, MTL7055, MTL7028, and MTL7265...
