3.0         BOARD DESCRIPTION

 

 

 

4.0         POWER TERMINALS AND CONFIGURATION

4.1      Power terminal

Regulated +10VDC or +30VDC at 2 Amps is required to power this board.  Additional amperage must be supplied if sourcing current on the open collector outputs or using the Expansion IDC26 ports to power breakout or relay boards.

                                              

 

⚠️

Check the polarity and voltage of the external power source and connect the 10VDC to 30VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source


4.2      Source Output 5VDC

The board can supply a regulated voltage to power external devices or circuits.

                                                                   

 

4.3      Source Output 10-30VDC                              

10-30VDC can be sourced to sensors or other cards requiring it.

                                                                                  


4.4      ERROR DRIVER


                          

In order to start the driver monitoring function, it is necessary to connect the driver Alarm to the ERR terminal.

8.0         E-STOP TERMINAL (24V)

Connect an E-STOP push button as shown in the images below.

                                              

 

Pin 10, port 1 is used for E-Stop.  Since this board controls the enable line, and the enable line is the one responsible for notifying the controller of the e-stop condition, the user does not have direct access to the pin itself, just to the e-stop terminal on the board. The E-Stop terminal is tied to the enable line and will trigger the E-Stop.   A fault or E-Stop triggers a low for 5 seconds to notify the controller of the fault condition, then resets to high again

💡

E-Stop on Pin 10, port 1:
Pin 10 is a special input; it is tied to the hardware enable of the system.

 

9.0         CONFIGURATION JUMPERS

9.1      Selecting the SCHP operation mode

 

The Safety Charge Pump can be activated or deactivated depending on the jumper position.  If the SCHP is enabled, the board will require the SCHP coming from the controller to be present in order to get activated (green LED).

9.2      Configuration jumper mode US or INT  

 

 Relay 1 and 2

They can be used to control the VFD. The relay specifications are shown in this table.

9.3      Relay 3 Operation can be assigned to pins 16 or 17 on port 2.

If assigning the relay to pin 17 on port 2 and using the Safety Charge Pump, then the relay will activate with the board is activated.  This can be very useful as it can be used to activate the main contactor for the system or relays that activate devices.

 

 



💡

Relay 1 and Relay 2

Set the VFD jumper 1 to INT and Jumper 2 to US, then access Relay 1 on pin 14 and Relay 2 on pin 16, both on port 2.
