FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the primary resolution for the analog output signal conversion?

A: The module converts data with a 12-bit resolution, providing an update rate of approximately 5 ms.

Wiring & Installation:

Q: How is the current range (0-20 mA or 4-20 mA) configured for the output channels?

A: The output current range is selected using jumpers located on the module's detachable terminal block.

Troubleshooting & Compatibility:

Q: What determines the output behavior of the module if the CPU enters the Stop or Reset mode?

A: A jumper on the terminal board configures the output to either default to the low end (0/4 mA) or hold the last valid state.

Replacement & Upgrades:

Q: What is the maximum continuous isolation voltage between the module field side and the backplane?

A: The maximum continuous isolation rating is 250 VAC, tested at 1500 VAC for one minute.
