Analogue Outputs

Analogue output circuit options are the same as the digital output options above. However, the heavy

power diodes and heatsinks are not necessary for analogue outputs. The T8297 distribution unit

includes two diodes for analogue output power bridging. The T8297 can be used with either the FTA

‘normal’ cables or the VFTA cables shown above for digital output modules. The same cables are used

for digital and analogue outputs.

The 24V supply should be wired to the centre connector and not to the studs.

The example below shows an FTA. A VFTA may also be used.
