CR1000 - Loggernet - water pump

Elvis.Kalnins Jul 26, 2021 09:40 AM


 I am wondering if it is possible to connect a water pump (Pedrollo CP 130) or water pump's inverter (Mitsubishi D700) to CR1000.

 The plan is to make a code inside CRBasic Editor that controls power, current or frequency for water pump based on flue gas temperature. (water is being sprayed in flue)

Look at the control signal types the pump inverter accepts. For the switch inputs on the inverter, you need to either use solid state relays or a SDM-CD16AC. The 5V signals from the C channels on the CR1000 are not high enough voltage. To use the analog input of the inverter, you would need a SDM-CVO4.
