JH4051I Datasheet | Unknown Manufacturer

PLUG-N-PLAY STRAIN GAUGE TRANSMITTER Features - - - - - - - Input Spans as low as 0.4m V/V (at 10V excitation) Offset and Nonstandard Ranges Available Excitation Adjustable from 4 to 12V Input/Output Isolation is Standard Quick-Check Red/Green Output LEDs Industry Standard Pinouts (11-Pin Socket) AC or DC Power Options DESCRIPTION Model JH4051I supplies DC excitation to a strain gauge or other resistance bridge, amplifies the bridge output and provides a proportional DC voltage or current. A fixed-range device, it is precisely calibrated to your specified range at the factory. Fully adjustable excitation permits use with bridge resistances as low as 120 ohms while staying within the transmitter’s 40m A excitation supply capability. A low-drift input amplifier maintains accuracy under varying ambient conditions. Input/output isolation is standard. Available options include AC or DC power choices and reverse-action Option RT (decreasing output with increasing input). Bridge applications other than strain gauges are possible: contact the factory with your requirements. HOW TO ORDER Model Number: JH4051I Power: Add suffix - AC (JH4051I-AC) for AC power or - DC for DC power. Specify 115Vac, 230Vac, 12Vdc or 24Vdc. Input Range: Specify range required in millivolts (m V), volts (V) or millivolts per volt (m V/V). For example, with 10V bridge excitation a range of 0/20m V is the same as 0/2 m V/V. See Specifications (on .. back) for input capabilities. Offset input ranges are allowed. Bridge Excitation: User-adjustable. Normally factory-set to 10V. For other settings specify any voltage between 4 and 12Vdc. (Note: 40m A maximum load. For 120ohm bridges, specify 4.8V or less.) Output Range: Specify any DC voltage or current range allowed by the “Output Capabilities” spec (see back). Reverse-Acting Transmitter: Decreasing output with increasing input. Specify Option RT. Loop-Powered Output: 4/20m A “current sink” output stage for connection to devices...
