PCL-731 – 48bit Digital I/O Card
131,00 € Excl. VAT
Features:
• 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 racks
Introduction :
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 port

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 -

• Supports Tx, Rx, RTS, and CTS signals
• Automatic RS-485 data flow control or RTS control PCL-847AIntroduction:
PCL-846/847 series cards provide four independent RS-422/485
serial ports on a card. Each port has a 16C550 UART with an on-chip
16-byte FIFO buffer for reliable, high-speed serial I/O. The UART
buffers data into 16-byte packets before putting it on the bus. This
drastically reduces the CPU load and avoids data loss when the
system is busy and cannot process the interrupt quickly. The UART
is especially useful for high speed serial I/O under Windows.
PCL-846 cards differ from PCL-847 cards in that they utilize
on-board optical isolators to protect your PC and equipment against
damage from ground loops, increasing system reliability in harsh
environments. To further increase reliability, PCL-846B/847B cards
include surge protection technology, protecting your system from
abrupt high voltage surges (up to 3000 V) such as those caused by
lightning during thunderstorms.An RS-485 Network with Automatic Data Flow Control
Using RS-232 Software
The RS-485 mode automatically senses the direction of incoming
data and switches its transmission direction accordingly. This feature
makes your network look and act just like an RS-232 network.
Application software written for half duplex RS-232 can be used
without modification. Moreover, you can simply and quickly build an
RS-485 network with just two wires.Specifications PCL-847A :

PCL-849A – 4 Port RS-232 Interface Card

(ICOM utility), DOS/Windows 3.1Introduction :
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.Specifications PCL-849A :
• Ports: 4 serial ports
