2 Safety
All safety information, notes and instructions specified in this manual must be strictly
observed. The product may only be used if all guidelines and safety instructions are
adhered to.
This product is operated in accordance with SELV or PELV. No imminent danger results
from the module itself. The use in Ex-Zone is permitted if additional measures are taken.
2.1 Intended Use

Only personnel with knowledge of ESD protective measures may modify or extend the
system or replace modules.
NOTE
Device damage due to electrostatic discharge!
When performing the work, make sure that the working area is free of static and
wear an ESD wrist strap.
If not used, ensure that the device is protected from electrostatic discharge, e.g.,
by storing it in its packaging.

X-AI 32 51 2 Safety
HI 801 181 E Rev. 4.00 Page 9 of 58
2.2 Residual Risk
No imminent danger results from a HIMax module itself.
Residual risk may result from:
Faults in the engineering
Faults in the user program
Faults in the wiring
2.3 Safety Precautions
Observe all local safety requirements and use the protective equipment required on site.
2.4 Emergency Information
A HIMax controller is a part of the safety equipment of a system. If the controller fails, the
system adopts the safe state.
In case of emergency, no action that may prevent the HIMax systems from operating safely
is permitted.

Page 10 of 58 HI 801 181 E Rev. 4.00
3 Product Description
The X-AI 32 51 standard module is an analog input module and it is intended for use in the
programmable electronic system (PES) HIMax.
The module is inserted in any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, refer to the System Manual
(HI 801 001 E).
The module is used to evaluate up to 32 analog input signals.
The standard module can be operated with safety-related modules within one base plate.
The standard module is non-reactive to the safety-related modules. In particular, this
includes EMC, electrical safety, communication to the X-SB and X-CPU modules and the
user program.
Module and connector boards are mechanically coded, see Chapter 3.6.1. This measure
ensures that a safety-related module cannot be replaced by a standard module.
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards
used to test and certify the modules and the HIMax system.
3.1 Safety Function
The module does not perform any safety-related functions.
The parameters and status for this module must not be used for safety functions.
3.1.1 Reaction in the Event of a Fault
If a fault occurs, the initial value (default value = 0) is transmitted to the user program for
the process values. The initial values must be defined by the users. If the raw value is
evaluated instead of the process value, the user must program the monitoring function and
the value in the event of faults from within the user program.
The module activates the Error LED on the front plate.
3.2 Scope of Delivery
The module must be installed on a suitable connector board to be able to operate. If a FTA
is used, a system cable is required to connect the connector board to the FTA. Connector
boards, system cables and FTAs are not included within the scope of delivery.
The connector boards are described in Chapter 3.6, the system cables are described in
Chapter 3.7. The FTAs are described in own manuals.

Production year (Prod-Year:)
Figure 1: Sample Type Label
3.4 Structure
The module has 32 analog current inputs (0/4...20 mA), each input is measured using an
internal measuring facility. A short-circuit-proof transmitter supply is assigned to each input.
The 32 analog inputs can be used to evaluate the values measured for the transmitters,
safety transmitters or wired contacts. Two-wire or three-wire transmitters with a maximum
supply current of 30 mA can be connected to the module.
The functional units are electrically isolated to ensure that the input signals are non-
reactive.
The processor system for the I/O module controls and monitors the I/O level. The data and
states of the I/O module are made available to the processor modules via the redundant
system bus. The system bus has a redundant structure for reasons of availability.
Redundancy is only ensured if both system bus modules are inserted in the base plates
and configured in SILworX.
The module is equipped with LEDs to indicate the status of the analog inputs,
see Chapter 3.4.2.

Table 11: Connector Boards for High Precision Measurements
3.6.1 Mechanical Coding of Connector Boards
I/O modules and connector boards are mechanically coded starting from hardware revision
AS00 to prevent them from being equipped with invalid I/O modules. Coding avoids
incorrect installation of invalid I/O modules thus preventing negative effects on redundant
modules and field zone. A part from that, invalid equipment has no effect on the HIMax
system since only I/O modules that are correctly configured in SILworX enter the RUN
state.
I/O modules and the corresponding connector boards have a mechanical coding in form of
wedges. The coding wedges in the female connector of the connector board match with the
male connector recesses of the I/O module plug, see Figure 5.
Coded I/O modules can only be plugged in to the corresponding connector boards.
