425 Analog and Digital Interface Three quadrature encoder channels for TTL or RS-422 inputs. Watchdog timer can control PC reset signal. 48 bidirectional digital signals for solid state relay boards. 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. You can request additional information by filling out this form.
