Signal inputs
Namur
Pulse input for connecting inductive
sensors with Namur interface accord-
ing to
EN 60947-5-6
Sensor supply: 8.2 V, max. 8.2 mA
Conversion of the sensor recording into digital information:
– Inactive: >2.1 mA Digital signal ON
– Active/pulse: <1.2 mA Digital signal OFF
– Hysteresis: 0.5 mA
Frequency range: 5 ... 9400 pulses/min (0.25 ... 157 Hz)
Pulse length: min. 200 s,
Use shielded connection cable for cable lengths >10 m.
Pulse input 3-wire
Pulse input for connecting inductive
sensors with
3-wire interface
Sensor supply: 24 V
Conversion of the input voltage into digital information:
– Inactive: 0 V/High-Z Digital signal OFF
– Active/pulse: 24 V Digital signal ON
– Hysteresis: ¼ U
max
Frequency range: 5 ... 9400 pulses/min. (0.25 ... 157 Hz)
Pulse length: min. 200 s,
Use shielded connection cable for cable lengths >10 m.
Analogue input 0/4 ... 20 mA
for connecting speed transmitter 4 ...
20 mA or position detectors from ser-
vomotors with power interface 4 ... 20
mA.
Range: 0/4 ... 20 mA, load 150 , accuracy ±1 %
Overcurrent limitation: approx. 25 ... 28 mA
Use shielded connecting pipework
Digital inputs
*
Nominal cur-
rent:
2.3 mA (230 VAC), impedance 100 k
2.1 mA (120 VAC), impedance 75 k
2.1 mA (24 VDC), impedance 11 k
Due to low currents on the contacts, use gold-plated silver con-
tacts.
Signal ON: 0.78 mA (230 VAC) 77 VAC
0.97 mA (120 VAC) 56 VAC
0.55 mA (24 VDC) 6.9 VDC
Signal OFF: 0.35 mA (230 VAC) 36 VAC
0.35 mA (120 VAC) 21 VAC
0.27 mA (24 VDC) 4 VDC
Electrically safe separation between the input and electronics,
floating
* Do not use for safety-relevant signals
