Single
Channel USB Relay Board w/IO Port 
|
|
|
Features
Low cost 1 channel USB relay board controlled through
the USB port, with 8 channel I/O port and 2 channel opto-isolated input
port.
 | Standard - 10 Amp 250VAC/28VDC SPDT power/general
purpose relays |
| Optional - SPST reed relays for fast switching and
high reliability, 200VDC/200VAC resistive 0.5A "-R" option |
Designed for single board operation -- one board per
USB port, up to 127 boards may be connected under PC control.
| ASCII commands to control relays. |
| Easy hook up using standard USB cable (included). |
| Commands are sent to the virtual PC
serial port created by the USB drivers. |
| 4800-38400 baud (default 9600 baud) |
| LED Indicators for relays |
Our boards utilize a USB to serial chip which allows a
seamless transition from RS232 boards to USB boards. The same software
may be used for both board versions and are interchangeable between our
USB and RS232 boards. All the same commands are utilized, including the
same communication protocols and baud rates. The USB driver creates a
virtual serial port -- your controlling software will not know the
difference.
Two versions available:
| Model: U1-RLY-IO-EXT - with general purpose/power
relay |
| Model: U1-RLY-IO-EXT-R - with reed relay |
Relay board enclosure (not included):
| Model: RLY-ENC-EXT-IO
- ABS plastic enclosure to fit both models above |
Relay testing software available for Windows to
program and verify the operation of
the relay board before writing your own software program.

units have a non-isolated 8 channel TTL compatible (0-5VDC) input or
output port, individually selectable as an input or an
output.
Additionally both boards have a 2 channel
opto-isolated input port capable of accepting up to 28VDC directly to
the pins. 5000V isolation, 4uS typical response time. 4 position
terminal block connection, 16-26 AWG wire.
Software:
Relay testing software
and additional software available for Windows is included on the
supplied CD.
Drivers:
Drivers included
for, Windows, Windows CE, Linux, and Mac on CD. |

Note:
The reed relay boards are identical to the standard units except they have
the reed relays installed. The reed relays are SPST and the common and
NO (normally open) contacts are used on the terminal block, the NC
contact is not used when these relays are installed.
Reed relays are typically used in low current,
fast switching, low bounce, and high reliability applications (up to 10
billion operations), as in ATE
equipment. No minimum current or voltage requirements. Reliability
tested to 1 billion operations (from the manufacturer's specifications).
Single pole single pole configuration. 200VDC/200VAC Peak Resistive,
reed relays are typically not designed for controlling inductive loads.
