HIMA HIMax® X-DI 32 02 Digital Input Module

Product Description

The X-DI 32 02 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 32 safety proximity switches (e.g., P+F), proximity

switches in accordance with EN 60947-5-6 (NAMUR) or wired contacts.

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 module and the HIMax system.

Safety Function

The module evaluates the input signals of proximity switches and contact makers and

monitors the proximity switch / contact maker circuit for open-circuits and short-circuits.

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 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. If the raw value is evaluated instead of the process

value, the user must program the monitoring function and the value in the event of faults

from within the user program.

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.
