Product Description

The IC693ALG221 provides four input channels, each designed to convert 4 to 20 mA analog signals into digital values for the PLC CPU. It is an “unisolated” module (channels share a common ground), making it a cost-effective choice for standard industrial monitoring where high-speed, high-density analog data is required.

Product Parameters

Key performance parameters for the IC693ALG221:

Key Advantages

• Fast Response: With a conversion rate of roughly 2 ms for all channels, it is excellent for dynamic processes that require rapid monitoring.

• Cost Efficiency: Provides four high-quality analog inputs in a single-width module, saving space on the PLC rack.

• High Resolution: 12-bit resolution ensures that the PLC can detect very small changes in sensor data.

• Easy Integration: Seamlessly integrates with the Series 90-30 CPU, with data mapped directly into the PLC’s %AI (Analog Input) registers.

Important Precautions

1. Common Ground: Because this module is single-ended/non-isolated, all four input channels share a common return. Be careful when wiring sensors powered by different sources to avoid ground loops.

2. External Power: This module requires +24 VDC from the backplane or an external power supply to power the internal sensing circuitry. If your PLC power supply (like the IC693PWR321) is overloaded, you must use an external source.

3. Shielding: Always use shielded twisted-pair cable for the 4-20 mA signals. Ground the shield at the PLC end only to minimize electromagnetic interference.

4. Signal Integrity: If a sensor signal drops below 4 mA (e.g., a broken wire), the digital value will drop to zero, which can be used in your logic to trigger a “Broken Wire” alarm.

Product Applications

The IC693ALG221 is primarily used to monitor environmental and process variables:

• Pressure Monitoring: Reading data from pressure transducers in hydraulic systems.

• Temperature Sensing: Interfacing with temperature transmitters (converting RTD or Thermocouple signals to 4-20 mA).

• Level Control: Monitoring fluid levels in tanks using ultrasonic or hydrostatic level sensors.

• Flow Measurement: Capturing data from flow meters for liquid or gas processing.
