Overview / Features
This product is a PCI Express bus-compliant interface board for output of digital signals. This product can output digital signals at 12 - 24VDC. DO-128L-PE features 128 opto-coupler isolated open-collector outputs (current sink type). In addition, output transistor protection circuit (surge voltage protection and overcurrent protection).
Windows/Linux device driver is supported with this product.
-
Opto-coupler isolated open-collector outputs (current sink type)
- DO-128L-PE card has 128ch opto-coupler isolated open-collector output with a 200?sec response time (current sink type). A separate common ground is provided for each block of 16ch inputs which means that each block can connect to a different external power supply. The drive voltage for both the inputs and outputs is 12 - 24VDC.
-
Opto-coupler bus isolation
- As the PCI Express bus (PC) is isolated from external signals by opto-couplers, this product has excellent noise torelance.
-
Windows/Linux support device driver
- Using the device driver API-TOOL makes it possible to create applications of Windows/Linux. In addition, a diagnostic program by which the operations of hardware can be checked is provided.
-
Output circuits include zener diodes for surge voltage protection and poly-switches for overcurrent protection.
- Zener diodes are connected to the output circuits to protect against surge voltages. Similarly, polyswitches are fitted to each group of 8ch outputs for over-current protection. Output rating : max 35VDC, 100mA per channel.
-
Functions and connectors are compatible with PCI compatible card
- The functions same with PCI compatible card PO-128L(PCI)H are provided. In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to migrate from the existing system.
