SP-DIO input/output expansion module
1126263051
Description
1126271883
The SP-DIO module is an input/output expansion with 4 non-secure inputs, 4 non-secure out-
puts and 4 non-secure input/output combinations whose function is configured using the sa-
mosPLAN
6 software.
The SP-DIO module offers the following functions:
• Monitoring of connected devices and sensors
For further information: Connecting devices [ch. 4, p. 43]
• Forwarding of input information to the controller module
• Receipt of control signals from the controller module and corresponding switching of out-
puts
The SP-DIO module cannot be operated alone; it always requires an SP-COP controller module
(see "samosPLAN
6" programming software).
It is possible to use multiple SP-DIO modules simultaneously (see System setup [ch. 3.2, p.
16]
). The voltage of the internal logic is supplied via the system connector and the internal sa-
fety bus. The voltage of the Y1–Y4 and IY5–IY8 outputs of the SP-DIO must be supplied di-
rectly via A1/A2 at the respective module.
Refresh rate
The LEDs of the I1–I4 inputs and the Y1–Y4 outputs or the inputs/outputs IY5-IY8 combination
show the state with a refresh rate of approx. 4 ms.
Restricted selection of inputs
Only the single-channel inputs are available to be selected in the configuration for the SP-DIO
expansion module, for example:
