FAQ
Frequently Asked Questions (FAQ)
Q1: What is the primary function of the SB401 module?
A1: The SB401 module serves as a communication interface over the ESB bus between the I/O modules and the Field Control Unit (FCU).
Q2: Can the SB401 module operate as a standalone unit?
A2: No, the SB401 must be installed within an ANB10S or ANB10D Node Unit. It cannot function independently.
Q3: Does the SB401 support redundancy?
A3: Yes, a Node Unit can host two SB401 modules to enable a redundant setup, improving system reliability.
Q4: Is the SB401 suitable for intrinsic safety (IS) applications?
A4: The SB401 itself is not intrinsically safe but can be used in Node Units that support explosion-proof configurations.
Q5: What precautions are needed during SB401 installation?
A5: Ensure the module is inserted into the correct slot and connected properly to the ESB bus. If modules with barriers are used, an insulating partition is required.
Q6: What are the dimensions and weight of the SB401 module?
A6: The SB401 measures 130 x 142.5 x 32.8 mm and weighs approximately 0.45 kg.
Q7: Is hot swapping allowed for the SB401 module?
A7: No, the SB401 does not support hot swapping. It must be replaced with the system powered down.
Q8: What accessories are required with the SB401?
A8: It must be used together with Node Units, Power Supply Modules (PW series), and ESB Coupler Modules (EC401/EC402).
