About the Manufacturer

The Simatic S5 is a hugely popular automation system produced by Siemens. Despite having been replaced by the Simatic S7 range. There is a massive number of Siemens S5 systems installed around the world and here at Northern Industrial we continue to supply and repair Simatic S5 modules for customers everywhere. Read on to find out a little bit more about the Siemens Simatic S5 system or contact us if you require any information or help with your existing S5 PLC or 6ES5988-3NB41.

Simatic S5 at a glance

The S5 family is split up into several different ranges; 90U, 95U, 101U, 100U, 105, 110, 135U and 155U. The higher the number, the more expensive and sophisticted the system, making them suitable for even the most complex of tasks.

Each chassis contains a power supply and a backplane with slots for several different option modules such as digital and analogue I/O modules, communication options such as Ethernet and serial communications, interface modules and special function modules.
