3 Product Description
DIO 24/16 01 is a plug-in module for the modular F60 HIMatrix system.
The DIO 24/16 01 module has 24 digital input channels and 16 digital output channels that
are galvanically isolated from the I/O bus. The status of the input and output signals is
displayed by LEDs located on the front plate next to the terminal plugs.
The module can be inserted in the F60 subrack's slot 3...8 as many times as required. Slots
1 and 2 are reserved for the power supply module and CPU module, respectively.
However, the load on the outputs must not exceed the total current input of the power
supply module.
The module has been certified by the TÜV for safety-related applications up to SIL 3 (IEC
61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1). Further
safety standards, application standards and test standards are specified in the certificate
available on the HIMA website.
3.1 Safety Function
The module is equipped with safety-related inputs and outputs.
3.1.1 Safety-Related Analog Inputs
Each group of 8 inputs is provided with a common, short-circuit-proof supply LS+ on the
clamps.
The safety-related application (SIL 3 in accordance with IEC 61508) of the inputs and the
sensors connected must comply with the safety requirements. For more information, refer
to the HIMatrix Safety Manual.
3.1.1.1 Reaction in the Event of a Fault
If the module detects a fault on a digital input, the user program processes a low level in
accordance with the de-energized to trip principle.
The module activates the
FAULT
LED.
In addition to the channel signal value, the user program must also consider the
corresponding error code.
The error code allows the user to configure additional fault reactions in the user program.
