The IA series of current sensors are rugged locomotive, industrial devices. These sensors accurately measure dc current and provide electrical isolation between the output of the sensor and the current carrying conductor. | Measuring Circuit | Units | IA-100 | IA-250 | IA-500 | | Full scale (FS) dc | +A | 100 | 250 | 500 | | Output | | | | | | Full scale output | V | 10.0 | 10.0 | 10.0 | | Sensitivity | mV/A | 100 | 40 | 20 | | Linearity (at +25°C) | % F.S. | 0.5 | 0.5 | 0.5 | | Maximum zero offset (at +25°C) | +mV | 50 | 50 | 50 | | Influence on Accuracy | | | | | | Maximum offset drift with temperature | +mV/oC | 2.0 | 2.0 | 2.0 | | Maximum sensitivity drift with temperature | +%/oC | 0.02 | 0.02 | 0.02 | | Withstand Capabilities | | | | | | Dielectric test | kV | 2.5 | 2.5 | 2.5 | | Output short or opern | | No Damage | No Damage | No Damage |
