In many plants the process signals are hard to read and control. If the display is dim or the wiring is wrong, operators may miss a critical alarm. This can cause waste, downtime, or safety issues. The Endress+Hauser RIA46 process indicator with control unit 20-250V AC/DC gives you a bright, easy-to-read display and built-in control functions, so you can see and act on data instantly.
Endress+Hauser RIA46 process indicator with control unit 20-250V AC/DC with Endress
You need a device that shows temperature, pressure or flow at a glance and also lets you adjust the signal. The RIA46 is a compact field-mounted indicator that works with 20-250 V AC or DC power. It reads voltage, current, resistance, RTD and thermocouple inputs and can drive analog or relay outputs. With Endress technology you get reliable signal conversion and alarm handling in one rugged unit.
