ELECTRICAL INSTALLATION
INSTALLATION RECOMMENDATIONS
•
Electronic and analog signal conductors should run through the plant separately from the output and supply conductors. If possible, in grounded
conduits.
•
The power supply for electronic instruments must come from a network suitable for instrumentation.
•
In control applications, you must consider what can happen when any part of the system fails.
•
We recommend the use of RC FILTERS (47 Ω and 100nF, series) in parallel with contactor and solenoid coils which are close or connected to
DigiRail-2R .
ELECTRICAL CONNECTIONS
Figure 2 shows the necessary electrical connections. Terminals 1, 2, 3, 7, 8 and 9 are for output connections, terminals 5 and 6 for the module
supply, and terminals 10, 11 and 12 for the digital communication. For better electrical contact with the connectors, it is recommended to use pin
terminals at the end of the conductors. For direct wire connection, the minimum recommended gauge is 0.14 mm² and must not exceed 4.00 mm².
Be careful when connecting the power supply terminals to the DigiRail-2R . If the positive conductor of the power supply source is
connected, even momentarily, to one of the communication connection terminals, the module may be damaged.
