1.0 FEATURES
•Can ships with the Ethernet Smoot Stepper Motion Controller installed
when purchased as a bundle.
•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
(Port_2 16 or 17, jumper-selectable).
•Microcontroller based SCHP (Safety Charge Pump).
•Optoisolated inputs working at 5-24VDC.
•Uses a single +10 to +30VDC to power the system. It generates the isolated
voltage for the spindle control circuit and +5vdc for circuits using TTL
logic.
•Status LEDs on all input and Output connections.
•DIN Rail mountable.
•Open Collector Outputs pins 1, 14, 16, 17.
•Screw-On connections for all terminals.
•Status LEDs for enable.
•Available installers and configuration files that configure all the functions
of the board.

4.0 POWER TERMINALS AND CONFIGURATION
4.1 Power terminal
The board can typically be powered with regulated +24vdc, but it can also work with anything
between +10VDC and +30VDC. The board itself will draw about 1 Amp, but we recommend
using a 2A and up so it can power external devices.
WARNING
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
Regulated +5vdc can be used to power +5vdc external devices.

4.3 Source Output 10-30VDC
The same voltage that is used to power the board can be used to power external devices.

6.0 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
7.0 CONFIGURATION JUMPERS
7.1 Selecting the SCHP operation mode
The Safety Charge Pump uses pin 17 on port 2. When the SCHP is enabled on the board, then
the output of the terminals will be active while the Safety Charge Pump signal is present and
inactive while the SCHP is not present.

Note: Also, that Relay3 on can also be tied to pin 17 or 16 on port 2. If the jumper is set to be
tied to pin 17, then the relay will activate while the system is active. This can be ideal to control
power to DC servos or to handle servo brakes. Or enable/disable any other feature that is
associated to the system been active.
