8B30 millivoltage input signal conditioners are designed for embedded applications to protect equipment in both the field and control room from power surges whilst reducing electrical noise in measured signals. Providing the very best specifications on the market in compact package, these 8B30 millivoltage signal conditioners isolate, filter and amplify a millivoltage input signal and output a high-quality analog signal for data acquisition and control.
Dataforth’s 8B30 millivoltage input signal conditioners provide an accuracy span of ±0.05% and linearity span of ±0.02%. A five-pole filter on the 8B millivoltage input signal conditioner provides signal filtering with 70dB of NMR (Normal-mode-rejection) at 60Hz, one pole of this filter is located on the field side of the isolation barrier for anti-aliasing and the other four poles are located on the system side. 8B30 millivoltage input signal conditioners also guarantee a high-level of reliability and long term stability with field I/O being protected against continuous voltages up to 240Vrms, as defined by the ANSI/IEEE C37.90.1 transient protection specification. The 1500Vrms transformer isolation barrier eliminates ground loops, allows for operation at high common-mode input voltages and rejects large common-mode spikes, all of which contribute towards preserving signal integrity whilst maintaining a high level of accuracy and output noise.
A regulated supply of +5V DC is required to power an 8B30 millivoltage input signal conditioner. Each 8B30 input module typically consumes 0.125w or 25mA of power at +5V DC. A wide range 12-28V DC24V DC DIN power supply converter or 230V AC rack mount transformer is available to power an 8B signal conditioning system.
These 8B30 millivoltage input signal conditioners have a wide operating temperature of -40°c to +85°c and have ATEX compliance pending. These signal conditioners are designed for installation in Class 1, Division 2 hazardous locations. Each 8B30 millivoltage input signal conditioner goes through a 48-hour burn-in operation and is 100% tested twice with test results provided.
Single-channel, dual-channel, 8-channel and 16-channel back panels with panel or DIN rail mounting options are available for the 8B30 millivoltage input signal conditioner.
