This Ethernet-compliant digital I/O unit provides a digital signal I/O in a PC LAN port. Digital signals can be input and output at 12 - 24VDC. This unit offers 16 optocoupler isolated input channels (compatible with both current sink and current source outputs) and 16 optocoupler isolated open-collector output channels (compatible with current sink type). Also, the unit includes a digital filter to prevent wrong recognition of input signals, an output transistor protection circuit (surge voltage protection and over current protection), and fail-safe function that sends communication errors.
16 optocoupler isolated input channels (compatible with current sink and current source outputs) and 16 optocoupler isolated open-collector output channels (compatible with current sink type).
This unit has 16 optocoupler isolated input channels (compatible with current sink and current source outputs) and 16 optocoupler isolated open-collector output channels (current sink type) whose response speed is 200μsec. A common terminal is provided per 8 channels, capable of supporting a different external power supply. Supporting driver voltages are 12 - 24 VDC for I/O. The digital input can be checked with the LED indicator.
A digital filter prevents wrong recognition of input signals from carrying noise or a chattering.
This unit has a digital filter to prevent wrong recognition of input signals from carrying noise or a chattering. All input terminals can be added a digital filter, and the setting can be performed by software.
Output circuits include Zener diodes for surge voltage protection and circuits for overcurrent protection.
Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, over-current protection circuits are fitted to group of 8 output channels. The output rating is maximum 60VDC, 100mA per channel.
Operable in a wide range of 12 - 24VDC power
The product can be operated in the various environments with a wide range power supply of 12 - 24VDC. In addition, the FG terminal is equipped in the power connector.
Fail-safe function
The fail-safe function is available when communication errors, such as LAN cable disconnection, occur.
Windows compatible driver libraries are attached
Using the API-DIO(WDM) attached digital I/O driver makes it possible to create Windows applications. In addition, a diagnostic program to check hardware operation is provided.
