SPECIFICATIONS Power Requirements Regulated +5VDC@ 500mA 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. POWER TERMINAL User’s Manual Page 2... -
Page 6: Enable Pin
Enable pin. The card must be provided with a 5VDC 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. When the enable signal is not present, output signals sent high impedance state. -
Page 7: Configuration Jumpers
CONFIGURATION JUMPERS Using the COM configuration jumper There is a jumper that allows you to select +5VDC or GND for the COM pins. 1-2: COM= GND 2-3: COM= +5VDC Using the Pins 2-9 direction jumper There is a jumper to select the pins 2-9 direction. 1-2: OUTPUTS 2-3: INPUTS User’s Manual... -
Page 8: Using The Pull-Up Or Pull-Down Selection Jumper For Pins 2-9
Using the Pull-up or Pull-down selection jumper for pins 2-9. Jumper allows to change the input configuration for 2-9. Using the Pull-up or Pull-down selection jumper for pins 2-9 the input voltage is pulled through a 4.7Kohm resistor to up or down in this way: 1-2: PULL-DOWN 2-3: PULL-UP... -

FUNCTIONAL BLOCK DIAGRAMS Bidirectional pins simplified block diagram Fig. 1 Simplified functional block diagram for the 2-9 pins. A Pull-up or Pull-down selection jumper allows selecting the configuration for the all bidirectional pins (2-9) when they are set as inputs. Dedicated Inputs simplified block diagram Fig. -
Page 10: Wiring Diagrams
10.0 WIRING DIAGRAMS While this board supports only TTL +5VDC signals, different kind of sensors, switches using different voltages can be connected using the diagrams that follow: Note. This board has two possible inputs 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. -
