Specifications
| Technical Data | AKT2G-AN-400-000 |
|---|---|
| Number of inputs | 4 |
| Thermocouple sensor types | Types J, K, L, B, E, N, R, S, T, U, C (default setting type K), mV measurement |
| Input filter limit frequency | 1 kHz typ.; depending on sensor length, conversion time, sensor type |
| Connection technology | 2-wire |
| Maximum cable length to the thermocouple | 30 m |
| Measuring range, FSV | in the range defined in each case for the sensor (default setting: type K; -200 … +1370°C) Voltage: ± 30 mV (1 µV resolution) up to ± 75 mV (4 µV resolution) |
| Resolution | Internal: 16 bit Temperature representation: 0.1/0.01 °C per digit, default 0.1°C Note: 16 bit is used for FSV calculation; so, value leaps >0.01°C will occur at resolution 0.01°C depending of which thermocouple is set; e.g. type K: approx. 0.04°C |

| Wiring fail indication | yes |
| Conversion time | approx. 2.5 s to 20 ms, depending on configuration and fil ter setting, default: approx. 250 ms |
| Measuring error | < ±0.3 % (relative to full scale value) |
| Voltage supply for electronics | via the E-bus |
| Distributed Clocks | - |
| Current consumption via E-bus | typ. 200 mA |
| Bit width in the process data image | max. 16 byte input, max. 8 byte output |
| Max. potential ±TC against ground | 2 V, important e.g. when operating with grounded thermocouples |
| Max. differential voltage between the ±TC inputs | ±15 V permanent |
| Electrical isolation | 500 V (E-bus/field voltage) |
| Configuration | via TwinCAT System Manager |
| Weight | approx. 60 g |
| Permissible ambient temperature range during operation | -25°C ... +60°C (extended temperature range), from firmware 06 |
| Permissible ambient temperature range during storage | -40°C ... +85°C |
