Loading capacity of the electronic outputs:  

ES/S x.1.2.1:

  • Rated current In per output: 1 A resistive load at Tamb up to 45°C
  • Inrush current per output: maximun 8 A for 2 min at Tamb up to 20°C

VAA/S x.230.2.1:

  • Rated current In per output: 160mA resistive load at Tamb up to 45°C
  • Inrush current per output: maximun 300 mA for 2 min at Tamb up to 60°C

 

Thermoelectric Valve Drive TSA/K 230.1 oder TSA/K 24.1:

TSA/K 230.1:

  • Operating current: 8mA
  • Max. inrush current: 300 mA during 200 ms max.

TSA/K 24.1:

  • Operating current: 75 mA
  • Max. inrush current: 250 mA during 2 min max.

TSA/K 230.2:

  • Operating current: 5 mA
  • Max. inrush current: <550 mA during 100 ms max.

TSA/K 24.2:

  • Operating current: 47 mA
  • Max. inrush current: <300 mA during 2 min max.

 

Summary - Maximum Number of Thermoelectric Valve Drives for one channel:

  TSA/K 24.1 TSA/K 24.2 TSA/K 230.1 TSA/K 230.2
VAA/S x.230.2.1 1 piece 1 piece 3 pieces 3 pieces
ES/S x.1.2.1 4 pieces 4 pieces 20 pieces 20 pieces
