Description
The Model 448 Output Relay Board
provides electromechanical relay contacts for the Model
404 or 408 Liquid Level Sensors, allowing those models
to be used as a control device.
The Model 448 Output Relay Board consists
of a power supply and five relays on the surface-mounted printed
circuit board. Four of the five relays are used with the Model
404. All five relays are used on the Model
408, refer to typical application.
Some liquid level control
applications may not require the alternating control, HOA
switches, or run-time meters (see the Model
403 or Model 407 data sheets).
The Model 404 and Model
408 Liquid Level Sensors uses the Model 448 to meet the
needs of direct relay control applications.
