+ 24 V for the 20 mA current loop interfaces.
Power supply modules are available with one or two backup batteries, depending on the model. These can be replaced even when the power supply is switched off. In the case of the power supply modules with only one backup battery, the backup voltage is supplied via sock ets during replacement.
