HIMA DIO 24/16 01 HIMatrix Safety-Related Controller

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.

Safety Function

The module is equipped with safety-related inputs and outputs.

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.

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.

Safety-Related Outputs

Each group of 8 outputs is provided with a connector on the clamps for the common

ground.

If an output channel is overloaded, it is switched off for ten seconds until the overload is no

longer present. If the module output range has a total load of more than 8 A, the outputs

are all switched off for 10 seconds and a new test is performed.

Reaction in the Event of a Fault

If the module detects a faulty signal on a digital output, the affected module output is set to

the safe (de-energized) state using the safety switches.

If a fault in the module occurs, all digital outputs are switched off.

In both cases, the module activates the FAULT LED.

The error code allows the user to configure additional fault reactions in the user program.

Line Control

The digital outputs DO 1 through DO 8 of the DIO 24/16 01 module can be used to monitor

the own digital inputs or the digital inputs of other modules (e.g., DI 32 01) for short-circuits

and open-circuits, e.g., for an EMERGENCY STOP button complying with Cat. 4 in

accordance with EN 954-1. To this end, the outputs are pulsed and connected to the

safety-related digital inputs. In this case, the outputs assume the function of pulsed outputs.
