Series F4 External Event Board

The external event output board is a multi-purpose circuit board for use with the Series F4
Ramping controllers. The Series F4 Ramping controller has 8 digital outputs that can perform
various functions including event outputs, boost outputs, and compressor control. These
outputs provide DC signals to drive devices such as Solid State Relays (SSR) or Silicon
Controlled Rectifier (SCR) power controllers. The external event board connects to these
outputs for additional output flexibility.

The external event board is available with either 2 or 8 outputs. Listed below are the three basic
output options:

1) Switched DC (A007-1732-F4C2 or C8)
This option provides a dc voltage for driving SSR and SCR power controllers similar to the
built-in output function, but with additional voltage and current capabilities.

2) SSR with contact suppression (A007-1732-F4B2 or B8)
This option provides an SSR contact capable of switching 24 to 253VAC at up to 0.5 amps.
Suppressors are contacted across the relay contacts for applications with inductive devices
such as relay coils.

3) SSR without contact suppression (A007-1732-F4K2 or K8)
This option provides an SSR contact capable of switching 24 to 253VAC at up to 0.5 amps.
These outputs are for driving resistive loads such as AC SSR inputs.
Note:
When controlling inductive loads such as relay coils, it is recommended that option 2 above
be used or add external contact suppression across the connected load.
