Serial/RS232 - 8 channel Relay card (& 8 + 8 DIO option)
 

 

SERDO8R - 8 channel relay card (PC104), serial port /RS232 control

Description:

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 connections.

Compatible with Windows 98SE/ME/2000/XP/Vista, MacOSX and Linux platforms.

Available with LabVIEW, Visual Basic, Visual C, VEE & Delphi example programs (see the 'downloads' section of our website).
