I need a PLC's for ventilation system and management of heat node equipment.
1. PLC with AI-2, 0-AO, DI-2, DO-6
2. PLC with AI-6, AO-4, AI-20, DO-17
3. PLC with AI-2, AO-1, DI-10, DO-18
4. Programmable regulator AI-7, DO-6
5. Programmable regulator AI-7, DO-6 VAS-AVS
6. Controller DI-10, DO-9
The project provided PLC's must have:
• analog inputs (0..10 V) - for sensors or other electrical signals;
• analog outputs - for continuous regulation (0..10 V) range;
• digital inputs - switches or other electrical equipment;
• digital outputs - equipment on and off via an intermediate relay (~ 24V / 0.1A).
Regulator must have LED display and control buttons to change parameters . Regulator has to have a real-time clock and communication channel for data exchange with PC. In case of power loss the regulator must ensure the preservation of parameters in memory.
Which controllers would you recommend?
Thank You.
