The Heron Multi-Function interface card enables you to simply and neatly connect multiple sensors, switches, etc. to your MCI irrigation controller. The card plugs into the 10 pin socket on your MCI controller.
Two Analogue Inputs
The analogue inputs allow Heron sensors or other analogue sensors to be connected to your MCI controller. The inputs accept a 0-5 V analogue level. Irrigation can either be initiated or suspended depending upon whether the analogue level is above or below the trip point.
One Flow Sensor Input
The flow sensor input allows either pulse or paddle wheel type flow meters to be connected to your MCI controller. Flow meters connect directly with no additional electronics. With a flow meter connected you can validate the flow on each irrigation valve. If the flow goes out of range the controller will alarm. You can also log the flow and volume of water used to a PC running Heron Ground Control software.
One Dosing Controller Connection
The dosing controller connection allows a Heron MPD dosing controller to be connected to your MCI controller. With a dosing controller connected different dosing recipes can be activated with differing irrigation programs.
Six Switched Inputs The switched inputs provide four Program Starts, one Remote Stop and one Remote manual Advance. The inputs accept a simple open/close switched contact.
One Alarm Output
The alarm output will activate when the controller has a fault or an alarm condition. The alarm output will drive a Heron Sensitive Relay (Order code REL1K).
Three Additional Outputs
The three additional outputs are activated by programs 2, 3 and 4 respectively. For example, these outputs can be used to control mechanical fertilizer injectors. The outputs will drive a Heron Sensitive Relay
