Power supply
There are various ways to provide the K Series
modules with power.
1 - Direct power supply to the modules by
connecting 24 Vdc power supply directly to
Terminals 7 ( + ) and 8 ( - ) of each module.
2 - Using the K-BUS connector accessory for the distribution of the power supply to the
modules via bus connector, in this way eliminating the need to connect power supply to
each module.
The bus can be supplied from any of the modules; the total absorption of the bus must be
less than 400 mA. Higher absorption values can damage the module. An appropriately
sized fuse must be connected in series to the power supply.
3 - Using the K-BUS connector accessory for the distribution of the power supply to the
modules via bus connector and the K-SUPPLY accessory for the connection of the power
supply.
The K-SUPPLY accessory is a 6.2 mm wide module that contains a set of protections
designed to protect the modules connected via bus against over-voltage loads.
The bus connector can be provided with power using the K-SUPPLY module if the total
absorption of the bus is less than 1.5 A. Higher absorption values can damage both the
module and the bus. An appropriately sized fuse must be connected in series to the power
supply.
The module has been designed for spring-type terminal
electrical connections.
Proceed as follows to make the connections:
1 - Strip the cables by 0.8 mm
2 - Insert a screwdriver in the square hole and press it
until the cable lock spring opens.
3 - Insert the cable in the round hole.
4 - Remove the screwdriver and make sure that the cable
is tightly fastened in the terminal.
