This universal analogue input display meter can be very easily custom configured to display the engineering units of the application eg. 0 to 10m for liquid level, 0 to 14 (pH), 0 to 50 (Hz), 0 to 6 (Bar) etc. etc. The configurable display range is -1999 to 1999 via 1 x analogue signal input (current 0-20mA or 4-20mA or voltage 0-10V or 2-10V). Default display is 0-100.0, for example 4mA = 0, 12mA = 50.0 and 20mA = 100.0


Available in 2 versions one display only, the other with a fully configurable relay output to control or alarm at a specific point on the scale. Select your required version when adding to cart
