FAQ

Q1: What is the main function of the A4 (RS-485) output?
A: Provides a two-wire digital channel for supervisory systems to retrieve data from all rack modules.

Q2: Does the B4 output provide 4–20 mA signals?
A: No, B4 provides buffered voltage (e.g., ±10 V). 4–20 mA outputs come from individual monitoring modules.

Q3: Can this module power other brands?
A: No, it is designed specifically for the ProvibTech rack and compatible modules.

Q4: Can it be used as a standalone power supply?
A: No, it must be inserted into a compatible monitoring chassis to function.
