4. Electrical Installation
The auxiliary voltage supply can provide 18-32 Vdc (24 Vdc nominal) to the field devices at a maximum
current of 1.5 A per channel, with the additional limitation that the total current drawn from the module must
not exceed 1.5 A. The supply is short circuit protected – if a short circuit is detected the supply to all four
channels will be disconnected to prevent damage to the module. If the cause of the short circuit is removed,
the auxiliary voltage supply will be restored automatically.
