Analog Devices Inc. 5B30-10-FC

Overview

5B30-10-FC from Analog Devices is a single-channel isolated voltage input signal conditioner that amplifies, filters, protects, and isolates millivolt-level analog signals. It supports ±10 mV input range, delivers 0 V to +5 V output, provides 1500 V_rms continuous isolation, and features chopper-stabilized amplification with ±1 µV/°C input offset drift - used in industrial temperature monitoring systems interfacing thermocouples or low-level sensor outputs.

For engineers reviewing the 5B30-10-FC datasheet, 5B30-10-FC pinout, 5B30-10-FC application, or 5B30-10-FC equivalent, key selection criteria include its 4 Hz bandwidth, 240 V_rms input protection, hot-swappable 2.27" × 2.32" × 0.595" module form factor, and compliance with FM Class 1 Division 2 and CSA hazardous location standards.

Technical Context

The 5B30-10-FC employs transformer-coupled isolation with proprietary modulation for linear signal transfer and includes a chopper-stabilized input amplifier delivering ±1 µV/°C input offset drift and ±0.05% span accuracy at +25°C. Its differential floating input eliminates need for field-side grounding.

Internal multi-pole low-pass filtering provides 4 Hz –3 dB cutoff, achieving 160 dB common-mode rejection at 50/60 Hz with 1 kΩ source imbalance and 60 dB normal-mode rejection. The series output switch enables active-low enable control with 6 µs selection time and 50 Ω output impedance.

FAQ

What is the input impedance of the 5B30-10-FC at power-on?

The 5B30-10-FC has a nominal input resistance of 5 MΩ when powered on, ensuring minimal loading of low-output sensors such as thermocouples and mV-range bridge transducers. This high impedance preserves signal integrity without requiring external buffer amplifiers. The 5B30-10-FC maintains this specification across its full –25°C to +85°C rated performance range.

Does the 5B30-10-FC require external power supply filtering?

No, the 5B30-10-FC includes internal regulation and filtering for its +5 V ±5% supply requirement. It draws 30 mA and exhibits only ±2 µV/Vs% power supply sensitivity referred-to-input, making it tolerant of typical industrial rail noise. No external capacitors or LC filters are needed for stable operation of the 5B30-10-FC in standard backplane installations.

Can the 5B30-10-FC be used with grounded thermocouples?

Yes - the 5B30-10-FC features a fully floating differential input circuit, so it accepts grounded, ungrounded, or exposed-junction thermocouples without requiring input grounding or bias resistors. Its field-side terminals (Pins 2 and 3) are isolated from both power and output commons, enabling direct connection to grounded sensors without measurement error or safety risk in the 5B30-10-FC.

What is the maximum common-mode voltage the 5B30-10-FC can withstand continuously?

The 5B30-10-FC supports up to 1500 V_rms continuous common-mode voltage between field-side input and computer-side output, meeting ANSI/IEEE C37.90.1 transient surge standards. This rating applies across its full operating temperature range and is validated per FM and CSA hazardous location approvals - a core specification of the 5B30-10-FC.

Is the 5B30-10-FC compatible with 5B Series backplanes from third-party suppliers?

Yes - the 5B30-10-FC adheres to the standardized 5B Series mechanical and electrical interface, including pinout, dimensions (2.27" × 2.32" × 0.595"), and hot-swap protocol. It operates identically in Analog Devices–branded and licensed third-party backplanes, provided they comply with the 5B Series User Manual specifications - confirmed for all certified 5B30-10-FC deployments.
