AC expansion device CL-LER.18AC2
Figure: 35: Inputs on the CL-LER.18AC2 expansion device
Connect the inputs, for example, to pushbutton actuators,
switches or relay/contactor contacts.
Input signal voltage range
• Off signal: 0 to 40 V
• On signal: 79 to 264 V
Input current
• I1 to I12 0.5 mA/0.2 mA at 230 V/115 V
• R1 to R12 0.5 mA/0.25 mA at 230 V/115 V
Cable lengths
Severe interference can cause a signal 1 on the inputs
without a proper signal being applied. Observe therefore the
following maximum cable lengths:
•I1 to I2 and
• R1 to R12: 40 m without additional circuit
