1.0 OVERVIEW
This card provides an easy way to connect your inputs and outputs from your port using
a LPH26pin Ribbon Cable or parallel port. Provides terminals for connections and
conditions signals for use in CNC applications.
2.0 FEATURES
•Terminal Block for all I/Os.
•Expansion port for Mother Board. Connect the C76 or ESS expansion board.
•Open collector Outputs pins optoisolated 2, 3, 4, 5, 6, 7, 8, 9, 1, 14, 16, 17.
•Input pins 10, 11, 12, 13, 15.
•Terminal Block input with close by ground or +5VDC connections, COM and
outputs with + 24VDC and ground
•Screw-On connections for all terminals. You only have to screw-on the wires to
make all your connections.
•Status LEDs for enable.
•Fully Optoisolated Inputs and Outputs.
•External Enable Pin

4.0 BOARD DESCRIPTION

User’s Manual Page 3
5.0 SPECIFICATIONS
5.1 Power Requirements
Regulated +5VDC and +12/24VDC is required to power this board.
WARNING
Check the polarity and voltage of the external power source and connect the 5VDC and
GND. Overvoltage or reverse-polarity power applied to these terminals can cause
damage to the board, and/or the power source.
6.0 POWER TERMINAL
To preserve optoisolation two independent power sources should be used. A +5vdc to power
the optos that interact with the controller (which could be a USB cable) and a +24vdc at 200
Amp to power the board..
Note. It can be polarized by Pin 26 of the IDC26

User’s Manual Page 4
6.1 Enable pin.
The card must be provided with a 24VDC signal to enable operation. This feature has
been added to externally control the status of the outputs. An external switch or a Safety
Charge Pump can be added to provide the enabling signal. If this function is not
required, a jumper can be placed between 24VDC and the EN terminal.
7.0 LED INDICATOR
The power LED lights indicate that the system is ready but disabled. When Status LED,
(Green LED) lights, it indicates that the system is enabled.

9.0 CONFIGURATION JUMPERS
9.1 Using the COM configuration jumper
There is a jumper that allows you to select +12/24VDC or GND for the COM pins.
10.0 EXAMPLE WIRING OPTOISOLATED OUTPUT
10.1 Wiring board
Fig. 1 Connection diagram of the card.
The power source of 12/24 VDC is for the correct functioning of the outputs of (2-9) and
(1,14,16,17).

11.0 WIRING DIAGRAMS
While this board supports input +5VDC signals, different kind of sensors, switches using
different voltages can be connected using the diagrams that follow:
Note. This board has two possible input banks, (bidirectional pins: 2-9) and (dedicated
inputs: pins 10, 11, 12, 13 and 15), and all the inputs of the same bank have the same
configuration. The below wiring diagrams are example, any input can be used for the
connections.
