Lead/Lag Controller
Includes: Lead/Lag Controller mounted in a plastic enclosure with mounting feet. The Lead/Lag Controller is used for controlling multiple pumps or HVAC units that require equal run time or failure changeover. The first application allows for up to (4) sets of devices and the other is for controlling (3) devices where (2) of the devices will be running all the time.
The Lead/Lag Controller has an on-board CommLink that provides for stand-alone programming and monitoring via a direct USB connection to a computer running Prism 2 software. If used on a networked system that has an external CommLink, this on-board CommLink would not be used.
The Lead/Lag Controller has (8) configurable analog inputs which will accept signals from thermistor temperature sensors or from 4-20mA, 0-5VDC, or 0-10VDC transmitters. The inputs are set for the desired scaling by means of a jumper bar.
An additional modular input is available for communicating sensors. The Lead/Lag Controller has (8) wet contact binary inputs that can be configured for either normally open or normally closed operation. Also available are (8) relay outputs for on/off control and (4) analog outputs (0-10VDC) for modulating control. There are (4) separate two events per day schedules which can be assigned to any input or output for operational control or for alarm recognition based on time of day.
