2.3Supply Voltage - Field Side
Ill. 4: Termination points for the supply voltage - Field side
The connection of the supply voltage is electrically isolated from the internal electronics. Two CAGE CLAMPS are always connected by a power contact. By this way, the power supply is taken to different points of the configuration.
It is possible to supply the following at the termination points (Ill. 4):
Volts: 24 V DC - Amps: 10 A DC
WARNING!
120 and 230 V AC can only be supplied via modules
The voltage is automatically supplied when the function modules are snapped together.
The ground (earth) contact makes first and breaks last conforming to electrical standards and can be used as protective grounding.
Depending on the I/O function, some modules do not have P.J.C.s. It is important to note this when assembling a node. Many modules require field side power, many do not. Please review the circuit diagrams of the individual modules. An additional power supply module may be necessary.
