Input current
• R1 to R12, I1 to I6, I9 to I12:
0.5 mA/0.25 mA at 230 V/115 V
• I7, I8: 6 mA/4 mA at 230 V/115 V
Cable length
Severe interference can cause the input of a signal condition
“1” without a proper signal being applied. Observe
therefore the following maximum cable lengths:
• R1 to R12: 40 m without additional circuit
• I1 to I6, I9 to I12: 100 m with input debounce switched on,
60 m without additional circuit with input debounce
switched off.
• I7, I8: 100 m without additional circuit
The following applies to expansion units:
With longer cables, connect a diode (e.g. 1N4007) for 1 A,
minimum 1 000 V reverse voltage, in series to the easy input.
Ensure that the diode is pointing towards the input as shown
in the circuit diagram, otherwise easy will not detect the 1
state.
