The JA Series is a powerful and versatile measurements grade analog transmitter/amplifier featuring selectable output formats for both voltage and current and is compatible with single or multiple summed transducers. Input, output, excitation and zero offset parameters are field configurable allowing for easy and convenient set up and calibration. Zero offsets are adjustable up to 100% of the span range. The JA Series utilizes a linear optical isolation of the input, output, and power that effectively eliminates ground loop potential. The JA Series is excellent for electrically noisy industrial environments and is available in both AC and DC power options. Other features include fine adjustment with no interaction between zero and span and remote sensing. The JA Series is an ideal choice for industrial applications where a transmitter/amplifier with a versed range of field selectable inputs and outputs is required.
| Operator Interface | |
|---|---|
| Status Annunciator | 2; Red LED for output; Green LED for input; Variable intensity. |
| Functional Test Pushbotton | Adjustable to 0-100% of calibrated range using integral potentiometer; Imposes preadjusted signal on the output, independent of any input signal. |
| Calibration Method | Range selection; Known signal input; Fine tuning potentiometer; Non- interactive zero and span signals eliminate “crosstalk” influences. |
| Adjustments | Integral potentiometers & switches; Zero offset (deadload); Transducer input ranging; Transmitter output ranging; Excitation voltage. |
