4.2 Terminal rating Inputs
Mains voltage: Input current depending on the operating state of the unit
Under voltage UMains 120 V UMains 230 V
∂ Safety shutdown from the operating
position takes place should mains
voltage drop
≤AC 75 V ≤AC 165 V
∂ Restart is initiated when mains
voltage exceeds
≥AC 100 V ≥AC 195 V
State inputs, temperature controller, temperature switch, load controller, pressure
switch, air pressure switch, actuator (except safety loop) of the contact feedback
network (CFN) are used for system supervision and require mains-related input
voltage
∂ Input safety loop See Terminal rating outputs
∂ Input currents and input voltages
- UeMax UN +10% UN +10%
- UeMin UN -15% UN -15%
- IeMax 1.5 mA peak
(peak value)
1 mA peak
(peak value)
- IeMin 0.8 mA peak
(peak value)
0.5 mA peak
(peak value)
∂ Contact material recommended for
external signal sources (air pressure
switch, pressure switch-min,
pressure switch-max, etc.)
Gold-plated silver contacts
∂ Transition / settling behavior /
bounce
- Perm. bounce time of contacts
when switching ON/OFF
Max. 50 ms
(after the bounce time, the contact must
stay closed or open)
∂ UN AC 120 V AC 230 V
∂ Voltage detection
- ON >AC 60 V >AC 120 V
- OFF <AC 40 V <AC 80 V
Analog input terminal X65 DC 0...10 V / DC 0/4...20 mA / 0...135 Ω
