Frequently Asked Questions (FAQ)
Q1: What is the Siemens 6EP1961-2BA00?
It is a SITOP select diagnostic module that distributes a 24 V DC input across 4 independently protected output channels, each rated for 10 A and adjustable from 2 to 10 A. It provides selective protection so that a fault on one channel does not affect the others .
Q2: How does selective protection work?
Each output channel has an electronic overcurrent trip that isolates only the faulted branch. When a channel trips, the other three channels remain powered and operational. This prevents a single short circuit from bringing down the entire 24 V DC system .
Q3: What is the adjustable trip current range?
Each channel can be set from 2 to 10 A via a potentiometer on the module .
Q4: Does this module have remote reset capability?
No. This model (6EP1961-2BA00) uses a button on the module for reset. It does not have a remote reset input. For per-channel diagnostics and different signaling options, the 6EP1961-2BA41 variant may be considered .
Q5: What is the signaling contact used for?
A common normally open (NO) contact (rated 0.5 A / 24 V DC) provides a group alarm when any output trips. This allows a PLC or monitoring system to receive a single fault notification without per-channel wiring .
Q6: Can I use this module with a SITOP DC UPS?
No. Siemens explicitly states that the SITOP select is not designed for operation with the DC UPS module 40 A (6EP1 931-2FC21/-2FC42) .
Q7: What is the input current rating?
The input is rated for 40 A at 24 V DC .
Q8: What is the efficiency and power loss?
Efficiency is 97% typical, with a power loss of 30 W at rated output .
Q9: What are the dimensions and weight?
Dimensions are 190 × 72 × 88.7 mm (H × W × D), with a net weight of 0.200 kg .
Q10: What is the country of origin and lifecycle status?
Country of origin is Austria. Lifecycle status is PM300: Active Product .
Q11: What should I verify before ordering?
Always verify the exact part number (6EP1961-2BA00 for the standard model), confirm your total load does not exceed 40 A on the input, ensure the adjustable trip range (2–10 A per channel) matches your branch loads, and check that the common signaling contact is sufficient for your monitoring requirements (consider 6EP1961-2BA41 for per-channel signaling).
