Siemens Automation and Drives is adding a fail-safe relay module and digital input/output (I/O) modules to its distributed Simatic ET 200S peripheral device.
The latter can therefore be installed in less space than before. This is especially advantageous in conveying applications and the manufacture of machine tools and production machines, as well as in the automotive industry, including robot technology, and in the paper industry.
The new fail-safe relay module for the Simatic ET 200S features a relay output for a switching capacity of 5A - at a DC voltage of 24V and an AC voltage of up to 230V. The relay module can be triggered via any fail-safe outputs. Internal fail-safe inputs can be used to read back the control information, and the module is certified for safety-related applications up to SIL 3 in accordance with IEC 61508 and IEC 62061 and is also in line with Category 4 according to EN 954-1.
With the new 8DI DC 24 V (eight-channel digital input) modules and the 8DO DC 24 V/0.5 A (eight-channel digital output) modules, the Simatic ET 200S requires less space than before. Typical uses where a large number of channels are needed and there is little space for installation are conveying applications and the manufacture of machine tools and production machines. The robust modules are suitable for ambient temperatures from 0 to 60 degrees C and are highly resistant to vibrations up to five 'g'. The electronic modules can be universally wired in advance with screw-type, spring-loaded or fast-connect terminals and can even be 'hot-swapped' without switching off the voltage supply. The 8DI modules are suitable for connecting two-wire sensors.
