SERDO8R - 8 channel relay card
serial port /RS232 control
(PC104) relay card fitted with perspex cover and base plate
The SERDO8R is a PC104
profile, eight channel, general purpose, serial (RS232) relay card.
The SERDIO8R offers an additional 8 general purpose DIO channels - accessed
via a header connector.
Designed to be connected to any
RS232 compatible serial port and commanded via a simple command
protocol. Each output can be independently set under software control.
The PCB tracking will handle 4.5 amps (relays have a 10 amp contact rating).
The card is available
with two screw terminal blocks which allow connection to all of the
NO/Com/NC contacts of the 8 onboard relays. A third screw terminal
block is provided giving user access to the 0V, 5V and 12V DC power
Compatible with Windows
98SE/ME/2000/XP/Vista, MacOSX and Linux platforms.
