SP-SDIO input/output expansion module
888376459
Description
888377995
The SP-SDIO module is an input/output expansion with eight safe inputs and four safe outputs.
It has two test signal generators: one for test output X1 and one for test output X2.
The SP-SDIO module offers the following functions:
• Monitoring of connected safety devices
For further information:
Connecting devices [ch. 4, p. 37]
• Forwarding the input information to the main module
• Receipt of control signals from the main module and corresponding switching of outputs
• Fast shut-off: Direct switch-off of the actuators connected on the module. This results in a
significant reduction in the response time of the entire system. Only 8 ms are needed in
the response times of the devices at the inputs and outputs in order to switch-off the out-
puts. The runtimes on the internal SBUS+ bus and the Logic Execution Time do not play
any role in this case.
Further information:
samosPRO system response times [ch. 12.1, p. 70]
• Activating or deactivating test pulses at the outputs (Q1–Q4) with firmware version V2.00.0
and higher.
Module SP-SDIO cannot be operated alone; it always requires an SP-COP COMPACT module
(see "samosPLAN5+" programming software).
It is possible to use multiple SP-SDIO84 modules simultaneously (see
System setup [ch. 3.2, p.
15]
). The voltage of the internal logic and the test outputs is supplied via the system connector
and the internal SBUS+ bus. The voltage of the Q1–Q4 outputs of the SP-SDIO must be supp-
lied directly via A1/A2 at the respective module.
ATTENTION
Limited short-circuit detection in the input circuits
• One SP-SDIO has two test signal generators, X1 and X2.
• Short-circuits between test signal generators of an SP-SDI or SP-SDIO expansion module
are detected. Between different modules the short circuit detection is then only ensured
if the test gaps of the test signal generators are < 4 ms, the test periods ≥ 200 ms and no
more than 9 modules (SP-SDI / SP-SDIO) have been plugged in. Short-circuits after 24
V DC (after high) at inputs that are connected to test outputs are detected independently
of the length of the test gaps.
Make note of this during wiring (e.g. through separate routing or protected lines)!
• The LEDs of inputs I1 to I8 indicate the state of the inputs at an update rate of about 64
ms.
