The input modules according to profile 7.3/7.4 are available with two or four input channels. It is possible in addition to convert the two-channel module to using only one input channel, thus enabling very short times before the analog value is available. The conversion is effected by means of a jumper plug at socket 3. The transmission times achieved with analog modules according to profile 7.A.9 are shorter by half than those achieved with profile 7.3/7.4. Operation is adjustable in this case, e.g. It is possible to choose with the ID1 code whether the module is operated with one or two channels. The output modules are configured as two-channel modules as standard. The input and output channels are electrically separated from the AS‑Interface network. If sensors with a higher power requirement are to be connected, more power can be supplied through the auxiliary voltage as an alternative to the internal supply.
