BOARD DESCRIPTION

POWER TERMINALS AND CONFIGURATION

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.

WARNING
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

Source Output 5VDC
The board can supply regulated voltage to power external devices or circuits.

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

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

**ANALOG I/O PORT PINOUT

**

The analog port contains 2 analog inputs and 2 analog outputs. This port also contains a 5Volts power output.

NOTE:
The analog signals are 0-3vdc and the discrete signals are also 0 or 3.3VDC. Keep in mind these signals are unbuffered and go directly to the pins of the uC. So be very careful by using them, make sure you do not exceed the rated voltage or allow a voltage differential to get to the pin.

E-STOP TERMINAL (24V)

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

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 a 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

CONFIGURATION JUMPERS

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).

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 activates. This can be very useful as it can be used to activate the main contactor for the system or relays that activate devices.
