More Information

Overview Manuals Input Signals Circuit Data Fault Detection Product Applications

Features:

  • NAMUR sensor and dry-contact discrete input
  • Defined 2.1 mA ON and below 1.2 mA OFF thresholds
  • Low-frequency state monitoring below 2 Hz
KL3103X1-LS1 provides a discrete-state input path for NAMUR sensors and dry contacts.

Defined current thresholds help maintenance teams distinguish an OFF state from a signal that has reached the ON level.

For service or selection, preserve the field-circuit type and diagnostic arrangement; a dry contact does not provide the same fault-detection behavior without the specified resistor pack.

Description
KL3103X1-LS1 handles discrete input signals from NAMUR sensors and dry contacts. Its 8 VDC ±1 VDC wetting voltage and defined current thresholds give engineers a clear basis for matching the field circuit to the intended input behavior.

KL3103X1-LS1 reports ON at 2.1 mA and OFF below 1.2 mA, while the configurable discrete-input channel is intended for dry contacts or state sensors changing below 2 Hz. This lets maintenance teams separate a signal-level problem from a rapidly changing input that falls outside the published operating description.
Technical notes
KL3103X1-LS1 uses different fault-detection behavior according to the field-circuit arrangement. A NAMUR sensor can support wiring diagnostics, while a dry-contact circuit requires the specified optional resistor pack for the diagnostic configuration. Before service, record the terminal wiring and channel setup, then restore them unchanged before checking the input state.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can KL3103X1-LS1 read a NAMUR sensor?
Yes. The input is specified for NAMUR sensors. Check that the field current crosses the published ON and OFF thresholds before treating a state problem as a module fault.
Can KL3103X1-LS1 be used with a dry contact?
Yes. Dry contacts are included in the published sensor types. If wiring-fault detection is required, the field circuit needs the specified optional resistor-pack arrangement.
Why does KL3103X1-LS1 show the input as OFF when the device is connected?
A current below 1.2 mA is interpreted as OFF. Measure at the channel, then trace the sensor/contact circuit and wetting-voltage path before replacing the module.
When KL3103X1-LS1 shows a blinking red Power/Integrity LED, should the module be replaced?
Not immediately. Emerson assigns a blinking red indication to a field-wiring fault, so trace the circuit first. A solid red indication instead points to an internal fault and changes the replacement decision.
Is KL3103X1-LS1 intended for rapidly changing pulse signals?
The published discrete-input description covers dry contacts or state sensors changing below 2 Hz. A faster pulse application needs separate manufacturer evidence for the intended signal path.
What should maintenance record before removing KL3103X1-LS1?
Record the sensor type and terminal/channel assignment, including any diagnostic resistor pack. Restore that same circuit before judging the returned input.
