- Emulates 5 Parallel Ports.
- 3 Expansion Ports for connecting additional breakout or relay boards.
- Two Analog Inputs and Two Outputs.
- Built-in PWM-Based Speed Control and Two Built-in Electromechanical Relays with NO and NC positions for spindle control.
- The system monitors:
- E-Stop
- Safety Charge Pump. - Electromechanical Relay with NO and NC positions for general purpose or tied to the Enable Signal (Port_2 16 or 17, jumper-selectable).
- Microcontroller-based Safety Charge Pump (SCHP).
- Optoisolated inputs working at 5-24VDC.

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.

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
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.
