SRP-94 / SRP-946
Digital Displays
The SRP-94 / SRP-946 digital display process meter converts analog input to working pressure or level in a digital display. It comes with a large Led display and value placements up to 6 digits for a wide variety of math functions. With multiple ranges of analog inputs for current or voltage the SRP-94/946 can be configured for analog and digital outputs using a 24V AC/DC power supply. Options include 2 or 4 relay outputs and RS-485 and Modbus RTU communications interface.
