Function relay Function relays can be used for complex control tasks.
The logic relay features the following function relays:
• Timing relay
•7-day time switch
•Year time switch
• Counter, up/down, high-speed, frequency
• Analog value comparator/threshold value switch
• Operating hours counter
• Master reset
• Text marker relay
Impulse relay An impulse relay is a relay which changes its switching state
and retains its new state (latched) when a voltage is applied
to the relay coil for a short time.
Input The inputs are used to connect up external contacts. In the
circuit diagram, inputs are evaluated via contacts I1 to I12
and R1 to R12.
CL-AC1, CL-DC1 and CL-DC2 can receive additional analog
data via the inputs I7, I8 and I11, I 12.
Interface The CL interface is used to exchange and save circuit
diagrams to a memory module or PC.
A memory module stores a circuit diagram and the CL
settings.
The CL-SOFT PC software allows you to control the logic
relay from the PC. For this the PC and the logic relay are
connected via the CL-LAS.TD001 cable.
Local expansion I/O expansion with the expansion device (e.g.
CL-LET.20DC2) is installed directly on the basic unit. The
connector is always supplied with the expansion unit.
