SP-SDIO input/output expansion module

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:
• Forwarding of input information to the controller module
• Receipt of control signals from the controller module and corresponding switching of out-
puts
• 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 safety bus and the Logic Execution Time do not play any
role in this case.
Further information:
• Activating or deactivating test pulses at the outputs (Q1–Q4) with firmware version V2.00.0
and higher.
The SP-SDIO module cannot be operated alone; it always requires an SP-COP controller modu-
le (see "samosPLAN 6 " programming software).
It is possible to use multiple SP-SDIO84 modules simultaneously (see
16]
). The voltage of the internal logic and the test outputs is supplied via the system connector
and the internal safety bus. The voltage of the Q1–Q4 outputs of the SP-SDIO must be supplied
directly via A1/A2 at the respective module.
Limited short-circuit detection in the input circuits
• One SP-SDIO module has two test signal generators, X1 and X2.
• 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
ATTENTION
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.
Take note of this during wiring (e.g. by using separate routing or protected lines)!
NOTICE
• The LEDs of inputs I1 to I8 indicate the state of the inputs at an update interval of about
64 ms.
