Features
  • One analog input to four outputs: Converts a single analog sensor signal into four independently configurable NPN open-collector ON/OFF outputs for multi-level monitoring and control.
  • Voltage and current input support: Selectable input modes support 0–5 V, 0–10 V, and 0–20 mA measurement, allowing connection to common 4–20 mA analog sensors.
  • 2,000 samples per second: High-speed sampling at 2,000 times per second combines with selectable 1–200 sample averaging to smooth noisy analog signals and stabilize control.
  • Independent four-level thresholds: Each output supports an independently configured threshold and hysteresis setting to reduce output chattering around the switching point.
  • Built-in sensor power and output delay: Provides a 24 VDC/200 mA sensor power supply and selectable 1–999 ms ON-delay or OFF-delay for easy integration with analog sensing systems.

Specification notes

  • The DMC-A4A current input mode measures 0–20 mA, allowing direct use with common industrial sensors providing a 4–20 mA analog output.
  • OUT1 through OUT4 support independent threshold and hysteresis settings with selectable HI-ON or LO-ON operation, allowing one continuous analog signal to be converted into multiple switching levels.
  • When mounting the DMC-A4A on a DIN rail, use the optional FA7EU end unit to secure the controller against movement.
FAQ

Q1: What is the DMC-A4A?
A: The DMC-A4A is an analog sensor comparator that converts one analog input signal into four independently configurable NPN open-collector outputs.


Q2: Which analog sensors can be connected to the DMC-A4A?
A: It supports sensors with 0–5 V, 0–10 V, and common 4–20 mA analog outputs.


Q3: How many thresholds can the DMC-A4A set?
A: Four independent thresholds can be configured, with detection results provided through OUT1 to OUT4.


Q4: What output type does the DMC-A4A provide?
A: It provides four NPN open-collector outputs, each rated for up to 50 mA at 30 VDC.


Q5: Can the DMC-A4A power the connected sensor?
A: Yes. It provides a built-in 24 VDC sensor power supply with a maximum capacity of 200 mA.


Q6: What is the sampling speed?
A: The analog input is sampled 2,000 times per second.


Q7: What does the averaging function do?
A: Selectable averaging from 1 to 200 samples smooths noisy or fluctuating analog input signals for more stable display and control.


Q8: Can hysteresis be configured?
A: Yes. Hysteresis can be configured independently for each of the four outputs to reduce chattering around the switching threshold.


Q9: Does the DMC-A4A provide output delay functions?
A: Yes. ON-delay or OFF-delay can be selected with an adjustable range of 1 to 999 ms.


Q10: What applications is the DMC-A4A suitable for?
A: It is suitable for multi-level control using analog sensors, including upper/lower liquid-level monitoring, film edge drift control, and converting distance, position, or level signals into multiple switching outputs.
