Introduction :
The PCL-849 series cards provide four individually configurable
RS-232 serial communication ports. The PCL-849A/849B/849L has a
16C554 UART which makes serial I/O more reliable. The higher
performance PCL-849+ has a 16C654 UART. By buffering data into
64-byte packets before putting it on the bus, UARTs drastically reduce
the CPU load. This makes the PCL-849+ especially suitable for high
speed serial I/O applications under multitasking environments.
The PCL-849 series cards support two operating modes, standard
mode and enhanced mode. In enhanced mode, the address for all four
ports can be set automatically. The PCL-849 series cards also support
either shared IRQ or independent IRQ functions. When an on-board
interrupt occurs, the interrupt status register (vector address) indicates
which port generated it. The shared interrupt can be set to most common
(extended) AT interrupts. This simplifies programming, speeds up
interrupt processing and frees up interrupts for other devices.

PCL-721 – 32 Channel D/I Card
156,00 € Excl. VATAdd to cartIntroduction PCL-721 :
The PCL-721/723 is a 32/24-channel digital input card with independent
interrupt capabilities that allows the PCL-721/723 to work in the
background while the processor perform other jobs in the foreground. With
this feature, your system can do real-time Process monitoring without
polling its inputs, channel by channel.The PCL-721/723 has two modes: normal and interrupt. While it is set to
normal mode, the PCL-721/723 serves as a general purpose multi-channel
digital input card. However,if it is set to interrupt mode, then each channel
will generate an interrupt request to the PC, once the channel input has
changed.The 32digital input channels ofthe PCL-721 are divided into 4 groups. The
24 digital input channels of the PCL-723 are divided into 3 groups. Each
group handles8 digital input channels. There is a register that reflects the
interrupt status of each groups. Users can first read this register to check
which group caused the interrupt, then by reading the 8channels’ status of
that group, you can easily find which channel generated the interrupt. This
two-pass feature saves lot of time to determine which service routine should
be executed in your ISR (Interrupt Service Routine).The PCL-721/723 is easy to configure. No switch or jumper settings are
needed (except the I/O base address). The IRQ level, individual channel’s
trigger mode (rising or falling edge), and interrupt mask (enable or disable)
are all software programmable -

also be used to control your stepping motors without any programming.
Digital I/O
The PCL-839 features 16 digital inputs and 16 digital outputs for general
I/O use (on/off control etc.).
Isolation protection
The PCL-839’s PULSE and DIRECTION outputs and five limits input
switches are isolated from the PC side.Features of PCL-839 :
· Three on-board pulse generators that enables simultaneous independent
control of three stepping motors
· Two operating modes – two-pulse (+ and – direction pulse) or one-pulse
(pulse-direction) mode

PCL-731 – 48bit Digital I/O Card
131,00 € Excl. VATAdd to cartFeatures:
• 48 digital I/O lines
• Emulates 8255 PPI mode 0
• Buffered circuits for higher driving capacity than the 8255
• Interrupt handling
• Output status readback
• Pin compatible with Opto-22 I/O module racksIntroduction :
The PCL-731 offers 48 programmable digital I/O lines. Each port
emulates the operation of an 8255 Programmable Peripheral
Interface (PPI) chip in mode 0, but provides a higher driving capacity
than the 8255.
The card’s DIO ports are combined into 8-bit ports, six for the
PCL-731. You can configure each port individually by software for
either input or output. The card can directly interface with SSR
module carrier boards through a 50-pin Opto-22 compatible
connector.
The PCL-731 is a low-cost alternative of the PCL-722. Like the
PCL-722 it provides a readback feature which lets you monitor the
status of the output by reading back the output portApplications
