≤ 1.6 W

Connection side

field side

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

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.
