The 7B14 series modules are signal conditioners that amplify, protect, filter, and isolate input voltages from a wide variety of two and three-wire platinum, copper, and nickel Resistor Temperature Detectors (RTDs). The module provides a precision output of either +1V to +5V or 0V to +10V, linear with temperature. All 7B14 series modules are mix-and-match and hot swappable.
The 7B14 module amplifies, protects, filters, and isolates input voltages from a wide variety of two‑ and three‑wire platinum, copper, and nickel RTDs. It provides a precision output that is linear with temperature and can be hot‑swapped in a backplane without disrupting power.
Designed for industrial signal conditioning, the module operates from a +14 VDC to +35 VDC supply, works over an ambient temperature range of –40 °C to +85 °C, and offers up to 1500 V rms common‑mode isolation. It is available in several configurations covering different RTD types and output voltage ranges.
