1734-IB8 AB Allen-Bradley PLC 24VDC 8 current sinking POINT Digital DC Input Modules 1734 Series Original brand new

1734-IB8 AB PLC 24V DC 8 current sinking POINT Digital DC Input Modules 1734 Series Original brand new

Digital I/O Modules
The 1734 digital I/O modules support:

A wide variety of voltage interface capabilities.Isolated and non-isolated module types.Point-level output fault states for short-circuit and wire-off diagnostics.Choice of direct-connect or rack-optimized communications.Field-side diagnostics on select modules.Safety applications up to and including SIL 3, Cat. 4, PL(e), when using 1734-IB8S or 1734-OB8S with a GuardLogix, SmartGuard 600, or GuardPLC controller.

POINT Digital DC Input Modules
The 1734-IB4D module is a 4-channel 24V DC input module with short-circuit and open-wire diagnostics. Catalog numbers ending with "S" are safety-rated.
