HIMA X-DI 32 52 Digital Input Module for ProximitySwitches and Wired Contact Makers

Product Description

The X-DI 32 52 standard module is a digital input module and it is intended

for use in theprogrammable electronic system (PES) HIMax.

The module can be inserted in any of the base plate slots with the exception

of the slotsreserved 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

proximity switches in accordance withEN 60947-5-6 (NAMUR) or wired

contacts.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, thisincludes EMC, electrical safety, communication to

the X-SB and X-CPU modules and theuser program.Module and connector

boards are mechanically coded, see Chapter 

This measureensures 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 standardsused to test and certify the module and the

HIMax system.

Safety Function

The module does not perform any safety-related functions.The module evaluates

 the input signals of proximity switches and contact makers andmonitors the

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

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) tothe user program.The initial values must be set to 0 to ensure that

the input variables transmit the value 0 tothe user program if a fault occurs.

If the raw value is evaluated instead of the processvalue, the user must program

the monitoring function and the value in the event of faultsfrom 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 FTAis used, a system cable is required to connect the connector board to the FTA.

Connectorboards, 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 32 inputs. Each channel measures the input signals through an

internalmeasuring facility.Four short-circuit-proof and current limited supplies feed

eight supply outputs each. Onesupply output is assigned to each input.The 32 inputs

can be used to evaluate the values measured for the proximity switches orwired contacts.

The switching thresholds for generating digital signals can be configured in SILworX.

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

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

redundantsystem 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 platesand

configured in SILworX.
