The PhidgetInterfaceKit 0/0/4 Provides a convenient way to interface your PC with
various higher-voltage devices such as incandescent bulbs, high-power relays, and
The 0/0/4 contains 4 Relay Outputs for switching AC or DC power; the relays
are Single Pole Double Throw (SPDT).
- Maximum DC Switching Voltage: 100VDC
- Maximum DC Switching Current: 5A
- Maximum AC Switching Voltage: 250VAC
- Maximum AC Switching Current: 10A
Note: When a relay is in one switch position for a period of time, oxidation
of the open contact(s) can occur. Depending upon the internal coating material of
the contacts, oxide films of varying density will be displaced upon the surface
of open contacts; this film acts as an insulator to current flow. When the relay
is switched, a certain amount of current flowing through the contacts, known as
the wetting current, is required to remove the film of oxides and ensure proper
conduction. Because of this requirement, these relays are not reliable for signal
switching. The minimum Switching Current is 100mA @ 5VDC.
