15-Bit Digital I/O Modules |
| |
The D1700 digital I/O
modules allow a host computer to control thousands of digital I/O points
from one serial port.
|
| |
| D1711
and D1712 |
| The
D1711 and D1712 Digital I/O modules contain 15 user-selectable
input/output bits. The bits can be individually programmed as digital inputs or
digital outputs. A user-programmable Initial value can be assigned to
each digital output bit, to turn "on" or "off" on
power-up.
The modules contain
a communications "watchdog" timer that can move the digital
outputs to a safe-condition in the event of a communications link
failure.
The modules contain
an Events counter that can be used to count positive transitions, from
logic "0" to a logic "1", on the B00 terminal. The
module can count pulses up to 10 million.
The D1711 contains
an RS-232 serial output and the D1712 contains an RS-485 serial output.

|
|
| |
| D1701
and D1702
|
| The
D1701 and D1702 Digital I/O modules contain seven digital input and eight
digital output bits.
The digital input
bits contain internal "pull-up" resistors. Therefore, a simple
set of contacts can be applied between a digital input bit and
ground.
The modules contain
an Events counter that can be used to count positive transitions, from
logic "0" to a logic "1", on the EV input terminal.
The module can count pulses up to 10 million.
The D1701 contains
an RS-232 serial output and the D1702 contains an RS-485 serial output.
