Source-input circuit

Input thresholds are referenced to L+, matching the module’s source-input wiring.

Sixteen-channel group

Omnes sedecim canales intrantes ad unum gruppus isolatum pertinent.

Nullum eventum interrumpit

Modulus statum intrantium et virides ledes status praebet, sine functionibus diagnosticis aut interruptus hardware.

Product Overview

6ES7321-1BH50-0AA0 sedecim signa intrantium 24 V DC in modulo S7-300 acquirit.

Intrantes electricae in uno gruppo sedecim isolantur et commutatores vel sensus proximitatis duorum-, trium- et quattuor-filorum compatibiles per conectorum frontalem 20-pinorum accipiunt.

Focus ordinandi: Circulum sensoris intrantis fontis et referentiam L+ serva dum modulus substituitur, non autem ut versionem conventionalis intrantis absorbentis connexas.

Key Functions

Legere sensus intrantes fontis

Limis ON est −13 ad −30 V relativum ad L+, cum circuitus signi pro operatione intrantis fontis connexus sit.

Filtrare mutationes signi

Utraque translatio intrantis usum fixi intervalli retardationis 1,2–4,8 ms habet.

Monitorare lo stato di ingresso localmente

Un LED di stato verde per ogni canale indica il suo stato di ingresso.

Quaestiones Frequenter Rogatae

Quod potentiale referentiae utendum est dum voltatio intrans in 6ES7321-1BH50-0AA0 aestimatur?

Limina voltationis intrantis ad L+ referuntur.

Num 6ES7321-1BH50-0AA0 sine mutatione circuitus pro modulo intrantis subtrahentis designati substitui potest?

Non, circuitus externus hanc dispositionem intrantium fontis huius moduli congruere debet.

Num omnes sedecim intrantes 6ES7321-1BH50-0AA0 ad temperaturam ambientem horizontaliter 60 °C activi manere possunt?

Ita, omnes sedecim intrantes activi esse possunt cum installatione horizontali usque ad 60 °C.

Does vertical mounting reduce the operating temperature limit for sixteen active channels on 6ES7321-1BH50-0AA0?

Yes, the limit for that arrangement is 40 °C.

Will 6ES7321-1BH50-0AA0 call an interrupt block when a channel changes state?

No, this signal module has no interrupt function.

Which front-connector size is required for 6ES7321-1BH50-0AA0?

Field signal transmitters connect through a 20-pin front connector.

Can I tune the input delay of 6ES7321-1BH50-0AA0 in the hardware configuration?

No, the input delay is fixed within the specified 1.2–4.8 ms range.

Compatibility & Ordering Notes

Before ordering 6ES7321-1BH50-0AA0: Retain the source-input wiring and 20-pin front connector, and account for the mounting-position temperature limit and absence of interrupt diagnostics in the installed program.
