Frequently Asked Questions
What type of sensors can I connect to this module?
Generally, you can connect standard 2-wire or 3-wire 24V DC sensors, mechanical switches, and proximity switches that meet the specified voltage ranges.
Does this module provide power to the connected sensors?
Yes, it can supply up to 500 mA from the L+ terminal. Specifically, this powers connected 2-wire sensors across all channels.
What is the difference between this and a high-speed input module?
This is a standard input module with a typical response time of 3ms. In contrast, high-speed modules have much faster response times (microseconds) for time-critical applications.
Can I use one channel independently if others fail?
The channels share a common power supply but are electrically independent for signals. Therefore, a fault on one channel (e.g., short circuit) typically does not affect the others.
From experience, what is a common wiring mistake to avoid?
Commonly, exceeding the total 500mA sensor supply current for all connected devices is an issue. Thus, always calculate the sum of all sensor currents to avoid overloading the internal supply.
Is diagnostic information available for this module?
No, this standard module has no diagnostic data. Instead, it only provides the binary input state. For wire-break or short-circuit detection, consider diagnostic input modules.
What is the meaning of the packaging unit (5 pieces)?
The module is sold in a factory-sealed pack containing 5 identical units. Consequently, this is convenient for stocking and projects requiring multiple identical modules.
