Event Outputs
The F4/F4T Controller has digital outputs which can be configured as Event Outputs to turn
remote devices on and off. There are four Event Outputs which are available for customer use.
Event Output 1 is dedicated for System Enable. Event Output 2 is dedicated for Humidity
Enable. Event Output 3 is dedicated for Purge. The Event Outputs 4 through 7 are available for
customer use.
Event Assembly (Option TE-1235)
The optional Event Assembly contains four 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, 5.0 Amps.
The event relays are just switches. You must provide power from an external source.
Connecting to the Event Assembly
1. Unplug the chamber from the power source.
2. Remove the top cover.
3. Locate the Event Assembly and connect your wires to the desired solid state relay terminals.
4. A 1/2-inch conduit hole is provided on the back panel to route your wires through. Use the
appropriate wire/cable management fittings.
