  • Solid-state relay: Max. switching capacity 30 V AC / 0.4 A or 40 V DC / 0.4 A.
  • Switching delay: Parameterizable from 100 ms to 20 s.
  • Switching hysteresis: Adjustable.
• Current output: 4-20 mA, active. Load max. 600 Ω. The value of the current output corresponds to the signal strength.

Power supply

• Supply voltage:
  • 85 to 253 V AC, 50/60 Hz.
  • 20 to 60 V DC or 20 to 30 V AC, 50/60 Hz.
