Introduction
The PCL-726 provides 6-channel analog outputs, 16-channel digital
inputs and 16-channel digital outputs add-on card for the IBM
Personal Computer and compatible computers. It is designed for
industrial control applications requiring analog outputs ( voltage and
current )with 12-bit resolution in rugged environment.
The PCL-726 transmits six analog outputs with individually user
configurable ranges of :
0 ~ +10V, 0 ~ +5V, ±10V, ±5V, and 4 to 20 mA current loop.
Each D/A has a double-buffered output for single-step update and
occupies its own I/O location. Also, A rugged and reliable 37-pin D-
sub style connector is provided for analog outputs.
In addition to the 6 analog outputs, the PCL-726 has 16 digital inputs
and 16 digital outputs, all of the digital channels are TTL compatible.
The PCLD-782 ( 16-bit Isolation digital input board)and PCLD-785
( 16-bit relay output board) are designed for going with the digital
input and output connection.
The PCL-726 uses the state-of-the-art technology and components to
design this card. Its compact size PCB board let this card easily fit
into any kind of chassis. Also, all the components on the card are
SMT type; it improves the reliability and quality of this card.
