DC coupling plate with 3 channels.
Presentation:
The FAL407 is a sign of coupling DC / DC, solid state, which will protect and enhance the digital outputs of your PLC. Constructed of a compact and for setting in standard DIN rail 35. Incorporated in itself, and the protections suppressor necessary in order to simplify its installation and save space in the panel.
General Characteristics:
Features of entry: (Trigger Signal)
Voltage input: 24VDC / Tolerability of 30%
Current input: 8 mA
Delay Trigger: 0.3 ms
Feature output:
Maximum working voltage: 37VDC voltage minimum of work: Current 20VDC maximum working: 2 A, resistive or inductive, 6 A by common. Delay of disengagement: 0.4 ms maximum switching frequency: 10Hz Resistance during the state ON: 0.12 W current maximum of departure (inrush current): 100 A
Current maximum of the active element remains: 23 A
Features of isolation:
Isolation between input and output: 3000VAC RMS;
Resistance of isolation: 1000M the 500VDC;
Differential characteristics:
It has a door fuse incorporated the plate, which protects all 3 outputs MOS, in the case of short circuit. The current of the fuse must not exceed 6 A. The series of diode of this suppression mounted on the board, so there is no need to put anything in parallel to the load. See details in the scheme of connection.
The active element does not suffer wear (MOS) and have long life, even as chaveador.

Electrical Connections:
As shown in figure beside it is the connector of entry. It has a post "C" which is the common of 3 entries. The type of entry can be NPN (common good) or universal, P / N, where the joint can positive or negative, must be specified in the request. Once below the connector, you can see the type of entry NPN or P / N and the code of the plate. The posts E1 to E3 are the entries of the plate. Á front of the posts are leds the indication of entries
The posts "0V" and "24V" of the connector must be connected to the power supply of cargo. The type of switching output is required NPN, or S1 to S3 comutam for "0V and common loads must be connected to the positive. We can see beneath the connector configuration and output voltage of work

Models Available:
• The only change possible in FAL407 boards is the type of entry, which must be specified by the user:
• FAL407N_ Configurada to command NPN, where the joint must be connected to positive (+24 V) of the source.
• FAL407_ Configurada to command NPN or PNP, which can be connected to the common negative (0V) or positive (+24 V) of the source.
• Other tensions of command or configurations are possible through consultation.
Why use cards coupling?
• It may seem illogical or redundant use of the coupling plates, but consider the following:
• Some exits of PLC really do not have sufficient capacity to handle more than 100 mA, and the obvious need for the use of couplers individual or group.
• All of coupling plates are electrically isolated protecting PLC of likely damage due to short.
• Cards PLC output with high density is lower cost.
Using up external couplers, cut up a source of heat and noise from inside the PLC.
• The cost to repair (or simply exchange it) a coupler is less than the repair of the digital output of a PLC.
• Not all cards, digital output of the PLC have fuses and protection from transient suppressor.
• The current gain of a coupler is significant, since it can operate with 16 mA 6 A (example).
• The electrical wiring becomes simpler and less costly, since the gauge of wire between the plate and PLC coupling can be significantly reduced. You can have the coupler near the load and to reduce the number of cables of great yardstick, taking only the sign of command (10 to 16mA) and food for the loads.
• Acopladores as FAL407 provide any other device of suppression, as diode inversely polarized in parallel with the load (diode in parallel with solenoids cause retardation of desacionamento).
