General conditions for electrical connections
The general conditions for electrical connections are identical with those of the KFG and KFGS
series. The data listed below are specific to CAN bus units.
KFGC (CAN bus), general conditions for electrical connections
Switching outputs: Type: Solid-state output, short-circuit-proof and overload-proof
Max. current-carrying - with simultaneous operation of 4 outputs 1.0 A
capacity: - with simultaneous operation of 2 outputs 1.25 A
- with operation of 1 output 1.5 A
Modes of operation: - Single operation
- Parallel connection of multiple outputs while simultaneously increasing
output current
Signal inputs: Type: digital solid-state input, short-circuit-proof
Connectivity: - Switching contact, no detection of wire breakage
- Dual wire sensors (e.g. piston detector), detection of wire breakage
