Description: 8-Relay Module (mains rated - 110V and 250VAC.) An extension of our Kit CPS74 (see next kit), PC controlled 8-Relay Board with 250V switching relays and added features. It is in a plastic case, latched relay operation, 250V relays switched in safety by using Dinkle connectors, and with 4 external inputs. Uses serial port so it can be located over 100 yards from the PC. Comes with case and end panel pieces as shown in the photos. Requires a center positive 9-to-12V DC power supply, at least 500mA, 2.5mm jack. Additional Details: Q: Can this module be used in standalone mode?
The kit is a boon to the Science Fair project, laboratory experimenter and so on. Uses serial port so it can be located over 100 yards from the PC.
It needs to be connected to a PC. However the state of the relays will be 'remembered' and will not change when disconnected from the PC.
Configuration Settings. Serial Port Name: The name of the serial port that the driver is connected to. COM1. Input Polling Interval: (optional) Interval time in milliseconds for inputs polling. Default value is 2000.
Set to 0 to disable the polling. Events Input State ChangedOccurs when the state changes on an input. Whenever Filter:. PropertyIndex: The index in the property's array. This is used for device properties that represent an array (or list) of values. EventArgs:.
Index: The index within the property array. NewValue: The new property value. PreviousValue: The previous property value.
Ready State ChangedThe device's running and ready state changed. Whenever Filter. None EventArgs:. NewValue: The new property value. PreviousValue: The previous property value. Instance Properties OutputStatesGet the relay states.
Accessibility: Read Only Type: OutputNamesGet the relay names. The QK108 does not provide configurable names so they are predefined.

Accessibility: Read Only Type: VersionGet the QK108 version. Accessibility: Read Only Type: ConnectedGets a value indicating if a connection is established with the QK108. Accessibility: Read Only Type: DeviceDisplayNameThe display name for this device.
Accessibility: Read Only Type: DeviceStartTimeThe date and time when this device was started. Accessibility: Read Only Type: DeviceLifecycleStageThe current lifecycle stage of the device. The stages in order are: Pending Start, Starting, Running, Stopping Accessibility: Read Only Type: DeviceIsRunningAndReadyIndicates if the device is ready for use, ie it is in the Running lifecycle stage and all properties are valid and all methods are ready to be used.
Accessibility: Read Only Type: Instance Methods TurnOnOutput ( Number )Turn on the specified relay if it is not already on. FinalValue: The value to set the property to after the duration of time has passed. SetPropertyForDuration ( String, Number, TimeSpan, Object, Object )Sets a property for a duration of time and then sets the property to a subequent value asynchronously. This action returns after setting the first value and the timer and subsequent property set run in the background. Subsequent sets of the same property will reset the timer if the subsequent value has not yet been set. This is an advanced feature, be sure to set the property name correctly.
