5B41-05-CY FEATURES

5B41-05-CY PRODUCT OVERVIEW

The 5B Series represents an innovative generation of low cost,high performance plug-in signal conditioners. Designed forindustrial applications, these modules incorporate highlyreliable transformer-based isolation and automated surface-mount manufacturing technology. They are compact,economical components whose performance exceeds thatavailable from more expensive devices. Combining 1500 V rmscontinuous isolation, +0.05% calibrated accuracy, small size andlow cost, the 5B Series is an attractive alternative to expensivesignal conditioners and in-house designsAll modules are potted and identical in pin-out and size (2.27” x2.32” x 0.595”). They can be mixed and matched, permittingusers to address their exact needs, and may be “hot swappedwithout disturbing field wiring or power. The isolated inputmodules provide 0 to +5V or +5V outputs and accept J, K, T, E,R, S, N, or B type thermocouples.These modules feature complete signal conditioning functionsincluding 240 V rms input protection, filtering, chopperstabilized low drift +1 uV/oC amplification, 1500 V rmsisolation, and sensor excitation when required.All modules feature excellent common mode rejection andmeet industrial transient surge withstand specifications.

5B41-05-CY GENERAL DESCRIPTION

The 5B40 and 5B41 are wide-bandwidth single-channel signalconditioning modules that amplify, protect, filter and isolateanalog input voltages. Both modules provide a 10 kHzbandwidth which ideally suits them to measuring signals thatvary rapidly with time. Examples include pressure inside aplastic injection molding machine, strain on an automobilechassis during a crash test and vibrations on a machine bearingshortly before failure.The 5B40 and 5B41 protect the computer side from damage dueto field-side over-voltage faults. All models withstand 240V rmsat their input terminals without damage thereby shieldingcomputer-side circuitry from field-side over-voltage conditions.In addition, 5B40 and 5B41 Series modules are mix-and-matchand hot swappable, so can be inserted or removed from anysocket in the same backplane without disrupting system power.A chopper-stabilized input amplifier provides low drift andstable gain. At the amplifier input, a stable, laser-trimmed zero-scale input offset is subtracted from the input signal to set thezero-scale value. For user convenience, the zero can beoptionally factory-set to meet custom needs, This allowssuppression of a zero-scale input value many times larger thanthe total span for precise expanded-scale measurements.A single-pole anti-aliasing filter resides at each modules input.A three-pole, low-pass filter in the output stage sets thebandwidth and yields optimal noise performance for accuratemeasurement of small signals in high electrical noise.Signal isolation by transformer coupling uses a proprietarymodulation technique for linear, stable and reliableperformance. The differential input circuit on the field side isfully floating, eliminating the need for any input grounding. Ademodulator on the computer side of the signal transformerrecovers the original signal, which is then filtered and bufferedto provide a low-noise, low-impedance output signal. Theoutput common must be kept within 3Vdc of power common.A series output switch eliminates the need for externalmultiplexing in many applications. The switch is turned on byan active-low enable input. If the switch is to be on at all times,the enable-input should be grounded to power common as it ison the 5B01 and 5B08 backplanes...
