1734-IB8S Allen-Bradley Digital DC input module

Product Dimensions：

• Safety digital inputs

– Safetydevices,suchasEmergencyStopPushButton,gateswitches,and safety light curtains, can be connected.

– Dual-channelmode evaluates consistency between two inputsignals (channels),which allows use of the module forsafety Category 3 and 4 and in applicationsthat are rated up to and including Performance Level e/SIL CL3when both channels’Point Mode configurations are set to Safety Pulse Test.

– Single-channelmode evaluatesone inputsignal(channel),whichallows use of the module forsafety Category 2 and in applications that are rated up to and including Performance Level d/SIL CL 2 when the channel's Point Mode configuration is set to Safety Pulse Test.

– Youcan configure a discrepancy time to control howlong two channels are allowed to be discrepant before a fault is declared.

– An externalwiring short circuit check is possiblewhen inputs arewired in combination with test outputs. The module must be wired in combination with test outputs when thisfunction is used.

– Independently adjustable on and off delays are available per channel.

• Test outputs (digital input modules only)

– Separate test outputs are provided forshort circuit detection of a safety input (orinputs). – Power(24V) can be supplied to devices,such assafety sensors. – Test outputs can be configured as standard outputs. – Specific test outputs can be used for broken-wire detection of amuting lamp
