Advantech PCM-3730 User Manual

PCM-3730
PC/104 16-Channel Isolated
Digital I/O Module
General information
The PCM-3730 offers 16 isolated digital I/O channels (8 DI
and 8 DO) and 32 TTL digital I/O channels (16 DI and 16
DO) on a PC/104 module. Providing 2500 V
PCM-3730
each I/O channels corresponds to a bit in a PC I/O port,
making the PCM-3730 very easy to program. The PCM-
3730 offers one PC interrupt with jumper-selectable IRQ.

The PCM-3730 interfaces with a wide variety of
Advantech daughterboards, 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
PCM-3730's 16-bit TTL digital output channels.
PCLD-785B provides 24 SPDT relays, while the
PCLD-885 provides 16 SPST power relays.
