1 Introduction
1.1 Validity of documentation
This documentation is valid for the product type E AI SHT2. It is valid until new documenta-
tion is published.
This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
1.1.1 Retaining the documentation
This documentation is intended for instruction and should be retained for future reference.
1.1.2 Terminology: System environment A and B
The PSSu system can be used in two different system environments. The module's applic-
ation area is described in the chapter "Intended Use" of the manual.
The distinction is made between
}PSSu in system environment A
}PSSu in system environment B
The distinction is based on the application area of the PSSu system.
PSSu in system environment A may be used in the
}Decentralised system PSSu I/O
}Not in the automation system PSS 4000
PSSu in system environment B may be used in the
}Automation system PSS 4000, e.g. with
– Decentralised system PSSu I/O with SafetyNET p
– Control system PSSu PLC
– Control system PSSu multi

2 Overview
2.1 Module structure
A module consists of
}Electronic module and
}Base module with
– Screw terminals or
– Cage clamp terminals
The base modules are the carrier units for the electronic modules and are used to connect
the field wiring. The electronic modules are inserted on to the base modules and determine
the module's function.
Details of the base modules that can be used are available in the chapter entitled “Intended
Use”.
2.2 Module features
The product has the following features:
}1 analogue current input
Current range:
0 ... 0.2 A, single-pole, referenced to earth
}2 analogue current outputs
Current range:
0 .. 20mA, single-pole, referenced to earth
– Scaling of input current 1:10 and 1:20
– Evaluation via analogue input module with an input resistance = 115Ohm, (e.g.
PSSuEFAI I), order no.: 312 260)
}For standard and failsafe applications in system environment A and B

3.1 Intended use
The module provides shunts to scale the current for analogue inputs. The module may be
used in conjunction with analogue current inputs (e.g. PSSuEFAII, order no.: 312 260).
The module may be used for standard applications in system environment A and B.
Intended use includes making the electrical installation EMC-compliant. Please refer to the
guidelines stated in the "PSSuniversal Installation Manual". The module is designed for use
in an industrial environment. It is not suitable for use in a domestic environment, as this can
lead to interference.
The following is deemed improper use in particular:
}Any component, technical or electrical modification to the module
}Use of the module outside the areas described in this manual
}Any use of the module that is not in accordance with the technical details.
The E AI SHT2 module may be used in conjunction with the following base modules:
}PSSu BP 1/8 S
}PSSu BP 1/8 C
}PSSu BP 1/12 S
}PSSu BP 1/12 C
}PSSu BP-C 1/8 S
}PSSu BP-C 1/8 C
}PSSu BP-C 1/12 S
}PSSu BP-C 1/12 C
