Supply
Connection	Power Rail or terminals 11+, 12-
Rated voltage	19 ... 30 V DC
Ripple	within the supply tolerance
Power dissipation	≤ 1.2 W
Power consumption	≤ 1.6 W
Input
Connection side	field side
Connection	terminals 4 (common), 1, 3 and 5 (supply -), 2 and 6 (signal -)
Input resistance	10 kΩ terminals 4 (common), 6-/2-
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 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
Time delay relative to input	7.1 ±0.3 µs
Ripple	in 200 kHz bandwidth < 20 mVrms in 20 kHz bandwidth < 3 mVrms
