Digital Output Connections
See page 12.9 of the “Series F4 User’s Manual” for details on how to connect to the Digital
Outputs.
Event Board Option
The event board option contains solid state relays to control AC operated devices, such as power
to a test sample. The solid state relays are rated for 24 to 240 VAC, 3.0 Amps. However,
TestEquity recommends derating the maximum current to 2.5 Amps. The solid state relay
mounting board is UL recognized/CSA certified for 120 VAC max. with the board-mounted
fuses; 250 VAC max. with a #22 solid copper jumper wire instead of the fuses.
Connecting to the Event Board
1. Turn the Main Disconnect switch to the OFF position.
2. Remove the lower door retaining screw located on the right side. Open the lower door.
3. The Event Board is located on the lower door. Connect to the event outputs as follows:
Event Output Event Board Terminals
Event 1 Not available
Event 2 3, 4 (Not available if GN2 Option is installed)
Event 3 5, 6
Event 4 7, 8
Event 5 9, 10
Event 6 11, 12
Event 7 13, 14
4. The event outputs are just switches. You must provide power from an external source.
5. A 1/2-inch conduit hole is provided on the left side of the lower door to route your wires
through. Use the appropriate wire/cable management fittings.
