Connection side

field side

Sensor supply

sensor supply depending on DIP switches configuration and external jumper: voltage: -18 V at 20 mA (short circuit limited at approx. 23 mA) current: 3.6 mA or 5.3 mA or 8.9 mA (±10 %) at -10 V reduced sensor supply option (-2.5 V compared to standard setting)

Input resistance

10 kΩ terminals 2 (common), 1 and 4

Transmission range

-20 ... 0 V extended voltage range : -20 ... 5 V

Voltage

-20 ... 0 V extended voltage range : -20 ... 5 V

Load

≥ 9 kΩ (3-wire sensor), ≥ 2 kΩ (2-wire sensor)

Output resistance

max. 5 Ω

Cut-off frequency

20 kHz (-1 dB)

Deviation

at 20 °C transfer error (with 10 kΩ load) < 20 mV, provided that the alternating component of the input voltage is not excessive, e. g. - square waves (0 ... 20 kHz): 5 V pp - sine waves (0 ... 20 kHz): the full span of 20 V pp (= 100 g peak acceleration at 100 mV/g) is acceptable.
