HIMA DI 24 01 HIMatrix Safety-Related Controller

Product Description

DI 24 01 is a plug-in module for the modular F60 HIMatrix system.

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.

The DI 24 01 module has 24 digital input channels for 110 VDC or 127 VAC that are

galvanically isolated from the I/O bus. The status of the signal inputs is displayed by LEDs

located on the front plate next to the terminal plugs.

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 analog inputs.

Safety-Related Analog Inputs

The module DI 24 01 has 24 digital input channels for 110 VDC or 127 VAC.

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.

Start-Up

To start up the controller, it must be mounted, connected and configured in the

programming tool.

Installation and Mounting

The module is mounted in the subrack of the modular HIMatrix F60 system.

Mounting and Removing the Modules

To mount and remove the modules, the connection cable clamp terminals must be

unplugged.

Additionally, personnel must be protected from electrostatic discharge. For details, refer to

Chapter 2.1.2.

Mounting the Modules

To mount a module into the rack

1. Insert the module as far as it can go – without jamming it – into the two guiding rails

which are located on the upper and lower part of the enclosure.

2. Apply pressure to the upper and lower extremity of the front plate until the module plugs

snap into the backplane socket.

3. Secure the module with the screws located on upper and lower extremity of the front

plate.

The module is mounted.

Removing the Modules

To remove a module from the rack

1. Remove the plugs from the module front plate.

2. Release the locking screws located on the upper and lower extremity of the front plate.

3 Loosen the module using the handle located on the lower part of the front plate and

remove it from the guiding rails.

The module is removed.
