HIMA H7505 Interface Converter Module for Safety Systems



The X-DI 64 01 digital 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 64 digital input signals. The digital inputs are current

sinking logic for 24 VDC signals in accordance with type 3 specified in the IEC 61131-2.

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).

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.

Safety Function

The module evaluates the digital input signals and provides them to the user program.

The safety function is performed in accordance with SIL 3.

Reaction in the Event of a Fault

If a fault occurs, the module adopts the safe state and the assigned input variables transmit

the initial value (default value = 0) to the user program.

The initial values must be set to 0 to ensure that the input variables transmit the value 0 to

the user program if a fault occurs.

The module activates the Error LED on the front plate.

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.

The new central modules support the various I/O modules of the previous generation.

The combination of the reliable HIQuad I/O modules and the new central module

has been named HIQuad X. This guarantees maximum compatibility for field installation.

This guarantees maximum compatibility and minimum modernisation effort in field installations.

As HIQuad X is now available, the H41q/H51q central modules have entered

the replacement phase of the HIMA product life cycle.

The H41q/H51q central modules will move to the legacy phase in 2020.

The legacy phase is expected to last 10 years and will be fully serviced.

The I/O levels will remain unchanged and will continue to be used in HIQuad X.

HIQuad X completes our intelligent security platform.
