Signal conditioning is provided for thermistors, RTD's, thermocouples, strain and pressure, resistance and voltage inputs. The on-board microprocessor continually scans the active sensor channels. The signal is amplified, digitized, filtered, converted to engineering units, and stored in on-board memory independent of the host CPU activity. It simplifies field wiring by converting ribbon cable connections to screw terminals. A temperature sensor on the 7409TB supplies a ninth channel with the temperature of the cold end of thermocouples.
Boards are interchangeable because each cold-junction is individually calibrated.
The Model 7409TC is designed for panel mounting and provides an interface between field wiring and our smart sensor processors. They have removable screw terminal blocks, a temperature sensor, prototyping area, and an analog signal conditioning area. We also offer a complete line of ISA bus products.
