1 General information
The modules are equipped with 2 safe analog input pairs for current measurement. Each input pair has its own
sensor power supply. The channels with their respective sensor supplies are galvanically isolated from each other.
It is possible to acquire current signals in the range of 0.5 to 25 mA.
The safe analog input modules are suitable for safely acquiring current signals for safety-related applications up
to PL e or SIL 3.
These modules are designed for X20 16-pin terminal blocks.
• 2 safe analog input pairs for current measurement 0.5 to 25 mA
• 24-bit digital converter resolution
• Channels individually galvanically isolated
• Sensor power supplies galvanically isolated
• Input filter configurable

- Page 2 X20(c)SA4430 1.1 Function Safe analog inputs This safe analog input module is suitable for safely acquiring current signals for safety-related applications up to PL e or SIL 3. openSAFETY This module uses the protective mechanisms of openSAFETY when transferring data to the various bus systems. Because the data is encapsulated in the openSAFETY container in a fail-safe manner, the components on the network that are involved in the transfer do not require any additional safety-related features.

Page 19: Minimum Cycle Time
X20(c)SA4430 11 Minimum cycle time The minimum cycle time specifies the time up to which the bus cycle can be reduced without communication errors occurring. Minimum cycle time 200 μs 12 I/O update time The time needed by the module to generate a sample is specified by the I/O update time. Danger! With regard to the I/O update time, an I/O update time of 200 ms should generally be considered for analog input modules with firmware version 301 or lower. - Page 20 X20(c)SA4430 13 Restart behavior Each digital input channel is not equipped with an internal restart interlock, which means that the associated channel data reverts back to the proper state automatically after an error situation on the module and/or network. It is the responsibility of the user to connect the channel data of the safe input channels correctly and to provide them with a restart interlock.
