Product Description

The X-AI 16 51 analog input module is intended for use in the programmable electronic

system (PES) HIMax.

The module can be 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 16 analog input signals.

Various modes of operation can be configured for the analog inputs:

• Voltage/temperature, voltage measurement in mV

• Thermocouples

• Current, current measurement in mA

• Pt100. (2-wire circuit, 4-wire circuit)

The module is designed for operation in accordance with the standards for Pt100

resistance thermometers (IEC 60751:2008) and thermocouples (IEC 60584-1:1998).

The module provides two current sources for operating the Pt100 resistance thermometer.

The module has been certified by the TÜV for safety-related applications up to SIL 1

(IEC 61508. IEC 61511 and IEC 62061).

A safety function in accordance with SIL 2 can be achieved with a 1oo2 modules structure

(Chapter 4.5.2), while a 1oo3 structure (Chapter 4.5.3) ensures a safety function in

accordance with SIL 3.
