SP-SDI input/output expansion module
888397323
Description
888398859
The SP-SDI module is an input expansion with eight safe inputs. If fulfills the following tasks:
• Monitoring of connected sensors
Connecting devices [ch. 4, p. 43]
• Forwarding of input information to the controller module
The SP-SDI module cannot be operated alone and always requires an SP-COP controller modu-
le (see "samosPLAN
6" programming software).
It is possible to use multiple SP-SDI modules simultaneously (see
). The voltage of the internal logic and the test outputs is supplied via the program remo-
vable storage device and the internal safety bus.
ATTENTION
Limited short-circuit detection in the input circuits
• One SP-SDI has two test signal generators. One test signal generator is responsible for
the odd-numbered test outputs (X1, X3, X5, and X7), while the other is responsible for
the even-numbered test outputs (X2, X4, X6, and X8).
• Short-circuits between test signal generators of a SP-SDI or SP-SDIO module are detec-
ted. Between different modules the short circuit detection is then only ensured if the test
gaps of the test signal generators are < 4 ms and the test periods
≥
200 ms. Short-circuits
past 24 V DC (after High) at inputs that are connected to test outputs are detected inde-
pendently of the length of the test gaps.
• Please ensure that the odd-numbered test outputs (X1, X3, X5, and X7) at the SP-SDI are
connected to a common test signal generator and that the even-numbered test outputs
(X2, X4, X6, and X8) are connected to another common test signal generator. Therefore,
short-circuits between the odd-numbered test outputs (X1, X3, X5, and X7) cannot be de-
tected. The same applies accordingly to the even-numbered test outputs X2, X4, X6, and
X8.
Make note of this during wiring (e.g. through separate routing or protected lines)!
