Application
1. Purposed:
a) For display only.
b) For control of system Hi-Lo setting values.
c) For analog or digital signal output. For central control or SCADA system
application.
2. Measured signals:
a) Voltage or Current.
b) AC or DC
3. Measuring range: For industrial system, the signal should very small such as mV, mA etc., and for power system purposed should be input V or A. The measuring display and output ranges are determined as required.
4. Input range: The meter input range can be accept from minimum mV to maximum V as required. Input can be accepted various and floating signal, and the terminals are all isolated from the external case, aux. power and input/output circuit.
5. Output range: AC&M has wide output range for available, various analogs 4~20mA or 1~5V etc., and RS-485 digital output.
a) For power system application, watthour and varhour has pulse output, based on the photo couple theory.
b) For Hi-Lo alarm setting functions, provide two SPDT setting points to trip or alarm the faulty system. The relay capacity has 120V, 5A continuous load.
c) For SCADA and central control systems, analog and digital output can be available, These meters combined with the traditional connection which has one display and one transducer separately.
6. Operation environment: The meter can be used under normal room temperature from -10’C to +55’C and relative humidity between 20 to 95 %.
