Input resistance: 10 kΩ terminals 4 (common), 6-/2-. Output current: terminals 4 (common), 5-: > 10 mA at -21 V or > 20 mA at -18 Vterminals 4 (common), 1-: 5.3 mA ±0.4 mA at -10 Vterminals 4 (common), 3-: 3.6 mA ±0.7 mA at -10 V, 20 °C (68 °F). Transmission range: -20 ... 0 V. Connection side: control side. Connection: terminals 7-, 8+. Voltage: -20 ... 0 V. Load: ≥ 9 kΩ (3-wire sensor), ≥ 2 kΩ (2-wire sensor). Output resistance: 24 Ω typ., 27 Ω maximum Since this is much less than the end-to-end resistance of a zener barrier, it may be necessary to specify a monitor intended for use without a barrier. Please follow the advice of the monitor manufacturer.. Cut-off frequency: 10 kHz (-0,1 dB) 20 kHz (-1 dB). Deviation: DC transfer error (with 10 kΩ load) < 10mV. After calibrationadditional error with AC superimposed is ±5 mV at 20 °C (68 °F) at any point within the span, provided that the alternating component of the input voltage is not excessive, e. g.- square waves (0 ... 20 kHz): 5 Vpp- sine waves (0 ... 20 kHz): the full span of 20 Vpp (= 100 g peak acceleration at 100 mV/g) is acceptable.Influence of ambient temperature(< 100 ppm of span)/K at any point within the span: .
