KL1408 ā (8) digital input, 24VDC
Figure 25: KL1408 Digital Input
The digital input terminals KL1408 (positive switching) acquire the binary control
signals from the process level and transmit them, in electrically isolated form, to
the server PC via the Beckhoff Bus Coupler. The Bus Terminals contain eight
channels indicating their signal state via light emitting diodes. They are particularly
suitable for space-saving use in control cabinets. With the single-ended connection
technique, a multi-channel sensor can be connected in the smallest space with
minimum wiring. The reference ground for all inputs is 0V.
Relay Output
KL2612 (2) Relays
Relay modules provide two relays per module. The KL2612 output terminal has
two relays connected to the power contacts, suitable for use up to 230VAC that
can generally be used for switching devices requiring main power. The Bus
Terminal indicates its signal state via a light emitting diode.
