• Important Comments Legal Principles 1 Important Comments To ensure fast installation and start-up of the units described in this manual, we strongly recommend that the following information and explanations are carefully read and abided by. 1.1 Legal Principles 1.1.1 Copyright This manual is copyrighted, together with all figures and illustrations contained therein. Any use of this manual which infringes the copyright provisions stipulated herein, is not permitted.
Important Comments Symbols • 5 1.2 Symbols Danger Always abide by this information to protect persons from injury. Warning Always abide by this information to prevent damage to the device. Attention Marginal conditions must always be observed to ensure smooth operation. ESD (Electrostatic Discharge) Warning of damage to the components by electrostatic discharge. Observe the precautionary measure for handling components at risk.
• Important Comments Safety Notes 1.4 Safety Notes Warning Switch off the system prior to working on bus modules! In the event of deformed contacts, the module in question is to be replaced, as its functionality can no longer be ensured on a long-term basis. The components are not resistant against materials having seeping and insulating properties. Belonging to this group of materials is: e.g. aerosols, silicones, triglycerides (found in some hand creams).

• 750-457 [4 AI DC ±10 V, Single-Ended] Display Elements The field side supply voltage of 24 V and 0 V for the input module is derived from adjacent I/O modules or from a supply module. The field supply voltage is passed on separately galvanically to following modules without own use. The supply voltage for the field side is made automatically through the individual I/O modules by means of power jumper contacts. Warning The maximum current of the internal power jumper contacts is 10 A.

The digitalized measured value is transmitted in a data word (16 bits) as input byte 0 (low) and input byte 1 (high) into the process image of the coupler / controller. This value is represented with a 12 bit resolution on bit B3 ... B14. The status information included in the three least significant bits (B0 ...
