The QUANCOM® USBREL4 is a professional output module with 4 SPST relays which are able to switch loads up to 1A / 15W. This module consits of a small case with a 9 pin D-SUB female header and a 1m USB cable attached to it. All relay contacts are conducted to the 9 pin D-SUB female header, so that it is very easy to connect external circuits by using a KAB-DSUB-9
9 pin D-SUB cable. You can use the module as dekstop device, in the laboratory environment, as mobile equipment connected to a Notebook.
The state of both relays is visualized through the onboard LEDs. The configuration LED shows that the module has power and if it is initialized by the driver. Up to 4 modules can be used at the same time in the same system by setting a unique module address using the onbaord jumpers to identify each module from software side.Additional Informations Connection examples for optocouplers and relays
The USBREL4 board is supported by QLIB (QUANCOM Driver Library) which makes it easy to program under Windows 7, Vista, XP, 2000, 98, Agilent Vee and LabView. We implemented a command set which is usable for all operating systems. An application generated for Windows 98 can be used directly on a Windows XP PC. You don't need any experience in driver development to program this device.
This USB module is also available as USBOPTOREL16
with 16 gav. isolated optocoupler inputs and 16 relays or as the low cost version USBREL8LC
without ouput LEDs and pluggable connector.
