Professional FAQ – Expert Buying Guide

Q1: What is the maximum number of I/O points with expansion?
A: You can reach up to 152 I/O points using HE-10 connector expansion modules. For screw terminal blocks, the max is 88 points.

Q2: Can I use this PLC for high-speed counting applications?
A: Yes. It has 3 channels at 5 kHz (16-bit) and 1 channel at 20 kHz (32-bit). Ideal for encoder or flowmeter inputs.

Q3: How do I protect the outputs from short circuits?
A: The relay outputs are not internally protected. Use external fuses or circuit breakers for each output group (COM0–COM3).

Q4: Is the real-time clock included?
A: No, but you can add a real-time clock cartridge in the free slot. The module also has a battery-backed RAM for data retention.

Q5: What is the typical scan cycle time?
A: Approx. 1 ms per 1K instructions plus system overhead of 0.5 ms. For most applications, this is under 5 ms total.
