HIMA X-DI 64 51 HIMax®Digital Input Module

Product Description

The X-DI 64 51 standard module is a digital input module and it 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 standard module can be operated with safety-related modules within one base plate.

The standard module is non-reactive to the safety-related modules. In particular, this

includes EMC, electrical safety, communication to the X-SB and X-CPU modules and the

user program.

Module and connector boards are mechanically coded, see Chapter 3.6.1. This measure

ensures that a safety-related module cannot be replaced by a standard module.

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 module does not perform any safety-related functions.

The parameters and status for this module must not be used for safety functions.

Reaction in the Event of a Fault

If a fault occurs, 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.

Structure

The module has 64 digital inputs (24 V) for digital signals, contact makers and proximity

switches (two-wire). For safely detecting a high level on the digital input, the voltage and

current thresholds must be exceeded (see Table 8).

The eight short-circuit-proof supplies feed eight supply outputs each (S1+ to S8+). One

supply output is assigned to each digital input.

The processor system for the I/O module controls and monitors the I/O level. The data and

states of the I/O module are made available to the processor modules via the redundant

system bus. The system bus has a redundant structure for reasons of availability.

Redundancy is only ensured if both system bus modules are inserted in the base plates

and configured in SILworX.
