*Wire: 0.3 … 3.3 mm2 (22…12 AWG). Torque: 0.2 … 0.4 Nm (2…4 lbf.in.). Pitch: 5.0 mm.

Constant voltage output (X20, X21:1)

Voltage: +10 VDC, 0, -10 VDC ±0.5% (Full scale range) at 25 °C (77 °F).

Temperature coefficient: ±100 ppm/°C (±56 ppm/°F) max.

Maximum load: 10 mA

Applicable potentiometer: 1 to 10 kohm

Analogue inputs (X21)

General: Two programmable differential current inputs (0 mA / 4 mA … 20 mA, Rin = 100 ohm) and one programmable differential voltage input (-10 V / 0 V / 2 V … +10 V, Rin = 200 kohm). The analogue inputs are galvanically isolated as a group (see Isolation and grounding below)

Isolation test voltage: 500 VAC, 1 min

Max. common mode voltage between the channels: ±15 VDC

Common mode rejection ratio:Resolution: 0.025% (12 bit) for the -10 V … +10 V input, 0.5% (11 bit) for the 0 … +10 V and 0…20 mA inputs

Inaccuracy: ±0.5% (Full scale range) at 25 °C. Temperature coefficient: ±100 ppm/°C max.
