Supply
| Connection | Power Rail or terminals 11+, 12- |
| Rated voltage | 19 ... 30 V DC Ur |
| 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 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 |
