2PCL-730 User's Manual
Introduction
The PCL-730 offers 32 isolated digital I/O channels (16 DI and 16
DO) and 32 TTL digital I/O channels (16 DI and 16 DO) on a PC add-
on card. Providing 1000 V isolation, each I/O channel corresponds to
a bit in a PC I/O port, making the PCL-730 very easy to program. The
PCL-730 offers one PC interrupt with jumper-selectable IRQ.
Features
• 32 isolated DIO channels (16 inputs and 16 outputs)
• 32 TTL-level DIO channels (16 inputs and 16 outputs)
• High output driving capacity
• High-voltage isolation on isolated I/O channels (1000 VDC)
• Interrupt capacity
• Two separate 20-pin connectors for isolated input channels and
output channels
• D-type connectors for isolated input channels and output channels
• High sink current on isolated output channels (200 mA/channel)
Applications
• Industrial ON/OFF control
• Contact closure monitoring
• Switch status sensing
• BCD interfacing
• Digital I/O control
• Industrial and lab automation

Daughterboards
The PCL-730 interfaces with a wide variety of Advantech daughter-
boards, such as the following:
PCLD-786 AC/DC power SSR and relay driver board
This board holds eight optically-isolated solid state relay modules and
provides an additional eight outputs to drive external relays.
PCLD-785B and PCLD-885 relay output boards
These boards let you control relays through the PCL-730's 16-bit TTL
digital output channels. PCLD-785B provides 24 SPDT relays, while
the PCLD-885 provides 16 SPST power relays.
PCLD-782B Isolated D/I Board
This board provides 24 optically-isolated digital input channels and a
cable to connect to the PCL-730's digital input ports.
PCLD-885
The PCLD-885 provides 16 SPST power relay channels with a
maximum contact rating of AC: 250 V, 5 A or DC: 20 V, 5 A. The
PCLD-885 can be driven directly by the digital outputs of PC-
LabCards through 20-pin flat-cable connectors or 50-pin OPTO-22
compatible connectors.
PCLD-780
This wiring terminal board makes analog or digital I/O connections
easy.
PCLD-880
The PCLD-880 is a universal screw terminal board for industrial
wiring. It can be used with the analog or digital ports of various PC-
LabCards via 20-pin flat cables or shielded round cables with DB-37
connectors.
