Question: An electrician is integrating a new flow sensor into an existing PLC system. The sensor provides a pulse output, with 100 pulses representing 1 litre of fluid. The PLC program needs to display total litres. What type of PLC input module is required for accurately reading this sensor?
Answer options:
- Analog input module
- Standard digital input module ✅ High-speed counter input module
- Relay output module
Correct answer: High-speed counter input module
Explanation: A high-speed counter input module is specifically designed to accurately count rapidly occurring pulses, which is essential for flow sensors that output pulses proportional to volume. A standard digital input might miss pulses at high flow rates, while analog inputs read continuous signals and relay outputs are for control.
