| OUTPUTS/INPUTS | |||
| Output: | Isolated 4-20mA dc, for both moisture and oxygen, 0-1, 0-2, 0-5, or 0-10 VDC for both moisture and oxygen (analog output can be configured to freeze during calibration) | ||
| Output range: | Scaleable to any range between 0-2ppb to 0-20ppm | ||
| Audible/visual alarms: | 4 oxygen levels, 4 moisture levels, temperature, electrolyte condition, moisture sensor diagnostic, loss of flow, zero verification, or calibration in process, moisture analyzer off-line, oxygen analog output freeze control during calibration | ||
| Dual scale range: | Two user selectable secondary analog output ranges for rescaling the output once the primary range is exceeded | ||
| Relay contacts: | 4 non-latching, independently assignable to oxygen alarms or oxygen calibration-in-process indicator, and 4 non-latching, independently assignable to moisture alarms. SPDT contacts rated for 5 amps at 30V dc. Up to 4 non-latching, independently assignable to alarms or indicators. SPDT contacts rated for 1amp at 30V dc. | ||
