2.2.5. Outputs
2.2.5.1. Relay outputs
The relays are able to switch voltages up to 36V. The max. current is 1A at a max.
power of 15W.
Additionally, the relays provide a safe electrical isolation of the module to the
connected equipment.
2.2.5.2. Timeout protection
The timeout-protection gives the possibility to switch-off automatically the outputs
to prevent damage. This takes place, if in a predefined time frame any
communication with the module was possible. Reasons could be cable disruption,
PC-crash and so on. This way damage control, surcharge of connected equipment
and risk of accidents can be avoided.
2.2.5.3. Visual control of the outputs (depends of module)
The state of each output is directly signalized by a separate LED. This simplifies to
detect and rectify wiring errors, because the signals on the cables are directly
observable.
Note: Only available for the USB-RELAIS-8 and USB-RELAIS-8_B module
