Shchad-E deaerator automation board

Input analog signals:

1. Water temperature: 100M, 100P, Pt100, 4-20mA, 0-20mA, 0-5mA; 0-1V;
2. Water level: 4-20mA, 0-20mA, 0-5mA; 0-1V;
3. Deaerator pressure: 4-20mA, 0-20mA, 0-5mA; 0-1V;

Input discrete signals (dry contact switching voltage DC 24V or AC 220V):

• minimum water level - dry contact
• maximum water level - dry contact
• minimum pressure in the deaerator - dry contact
• pressure in front of the vapor cooler maximum - dry contact

Output control signals (valve supply voltage DC 24V or AC 220V):

• water supply valve control (level circuit)
  1. 0-10V
  2. 4-20mA
  3. more / less regulation
• steam valve control (temperature circuit)
  1. 0-10V
  2. 4-20mA
  3. more / less regulation
• steam valve control (pressure circuit)
  1. 0-10V
  2. 4-20mA
  3. more / less regulation

Output discrete signals:

• deaerator failure - dry contact
