概要・特点
This product is a PCI bus-compliant interface board that counts input pulse signals from external devices. This product has four channels of 24-bit up/down counters, allowing external devices such as a rotary encoder and a linear scale to be connected. Given below are examples of using the board for “detecting a position of
the table of a machine tool” and “detecting a change in weight”. The pulse signal inputting interface is opto-coupler isolated or TTL-level input.
Windows/Linux device driver is supported with this product.
-
It is equipped with four channels of 24-bit up/down counters.
- 24-bit up/down count for 4 channels can be performed with one board.
-
The board can count two-phase signals, which can be outputs of some rotary encoders and linear scales
- Two-phase signals such as rotary encoders and linear gauges can be counted.
-
You can select either a photo coupler isolated input or a TTL-level input for each channel by software command.
- Either differential input or TTL level input can be selected for each channel individually.
-
Each channel can generate an interrupt request signal and a one-pulse output signal when the count data matches a pre-specified value.
- An interrupt can be generated or a signal can be output externally by matching the count value of each channel with an arbitrarily set value.
-
The board is equipped with a programmable timer to allow interrupts to be generated periodically according to a specified timer value.
- It has a programmable timer, it is possible to generate interrupts at regular intervals with a set timer value.
-
Each Channel is equipped with a general-purpose input signal (both opto-coupler and TTL-level).
- Equipped with one general-purpose input signal for each channel. (both opto-coupler and TTL-level).
