Output rated operating current		terminals 4 (common), 5-: > 10 mA at -21 V or > 20 mA at -18 V terminals 4 (common), 1-: 5.3 mA ±0.4 mA at -10 V terminals 4 (common), 3-: 3.6 mA ±0.7 mA at -10 V, 20 °C (68 °F)
Transmission range		-20 ... 0 V
Output
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.
Transfer characteristics
Cut-off frequency		10 kHz (-0,1 dB) 20 kHz (-1 dB)
Deviation		DC transfer error (with 10 kΩ load) < 10mV
	After calibration	additional 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 V_pp - sine waves (0 ... 20 kHz): the full span of 20 V_pp (= 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
Time delay relative to input		7.1 ±0.3 µs
