The IOy Edge I/O Module is the ideal choice for projects requiring simple yet reliable analog monitoring and control.
Case Details
In many automation projects, PLCs are commonly used for analog signal acquisition and control. However, for scenarios that only require basic threshold monitoring without complex PID regulation, PLCs often mean higher costs and unnecessary complexity. The IOy Edge I/O Module provides a lightweight, reliable, and cost-effective alternative.
Application Scenarios
- Analog data acquisition (temperature, pressure, liquid level)
- Threshold-based control logic
- Simplified monitoring without advanced PID control
Typical Examples
1. Temperature Control
- Connection: AI1 connected to a PT100 sensor
- Logic:
- Temperature > 50℃ → DO2 starts the fan
- Temperature < 30℃ → DO2 stops the fan
Ensures stable equipment operation and safe thermal management.
2. Liquid Level Control
- Connection: AI2 connected to a 4–20mA level sensor
- Logic:
- Level < 10% → DO3 opens inlet valve
- Level > 90% → DO3 closes valve
Achieves automatic water tank filling and overflow protection.
3. Pressure Alarm
- Connection: AI3 connected to a pressure sensor
- Logic: Pressure > 0.8MPa → DO4 triggers sound & light alarm
Provides real-time safety alerts to prevent overpressure risks.
Value Delivered
- PLC Replacement for Basic Control – lower cost, simpler deployment
- Built-in Logic Processing – executes threshold actions locally without host intervention
- MQTT Protocol Support – direct cloud/SCADA integration for remote monitoring
- Industrial-Grade Reliability – isolation, EMC compliance, and wide temperature operation
The IOy Edge I/O Module is the ideal choice for projects requiring simple yet reliable analog monitoring and control. From temperature management to liquid level automation and pressure alarms, it enables cost-effective, IoT-ready solutions that go beyond traditional PLC limitations.
