Data Sheet – Siemens SITOP PSE200U

Article No.: 6EP1961-2BA61
Model: SITOP PSE200U/4x0.5–3A/SEO/NEC CLASS 2
Description: 4-channel selectivity module, 24 V DC, NEC Class 2, adjustable 0.5–3 A per channel.

Input

• नेटवर्क type: Controlled DC voltage

• Rated supply voltage: 24 V DC

• Input voltage range: 22–30 V

• Overvoltage capability: Up to 35 V

• Input current (24 V): 12 A

Output

• Output voltage: Controlled DC, approx. Vin – 0.2 V

• Voltage tolerance: As per supply input

• Number of outputs: 4

• Rated output current (each): 3 A up to 60 °C

• Adjustable trip current: 0.5–3 A (via potentiometer)

• Max response delay: 5 s

• Parallel switching: Not supported

Output Behavior

• All outputs connect simultaneously after input voltage > 20 V

• Delay: 25 ms, 100 ms, or “load-optimized” (via DIP switch)

Efficiency

• Efficiency: 97%

• Power loss: 9 W

Switch-off Characteristics

• Overcurrent:

  • 1.0–1.1 × set value → switch-off ~5 s

• Current limit:

  • 1.1 × set value → switch-off approx. 100 ms

• Immediate shutdown:

  • Iout > set value AND Vin < 20 V → ~0.5 ms

• Residual current at cutoff: 1 mA (typ.)

Reset / Signaling

• Reset method: Sensor reset per output

• Remote reset: 24 V input, non-isolated (> 15 V = HIGH)

• LED Indicators (per output):
