【英文介绍】
Features:
Analog output and accumulator pulse output
Use the multi-function keyboard for local configuration
Assignable alarm Settings
Optional decimal point position
Schneider Electric/Invensys/Foxboro 75 rta rate meter based on single loop microprocessor/accumulation is used to need a flow indicator and the application of traffic. All-in-one multi-function keyboard allows local configuration and operator control.
75RTA features include:
• Pulse inputs for flow, or 4 to 20 mA inputs for flow or differential pressure • Analog outputs and accumulator pulse outputs • Panel mounted versions, or NEMA 4X field mounted versions
• Small size and weight
light
• Easy to read fluorescent display; Total 10 characters, rate 6 characters • Optional decimal point position for displaying rate and total - display two variables at the same time
• Simply connect to the instrument terminal (TB1)
With the correct terminals, you can supply 120 V AC, 220 V AC or 24 V DC
The input/output loop can be externally or internally powered. If 120 or 240 V AC input power is used, internal power supply is provided.
