Breakout board, 40-pin, with temperature sensor | Model 7409TB
- Connects 8 sensors to any Sensoray smart sensor interface board
- Supports 4-wire sensor connections
- Screw terminals for easy field wiring
- Cold-junction transducer for thermocouples
- Compact size: 4.6 x 2 inches
Description
The Sensoray Model 7409TB Termination Board provides a low-cost interface between sensor field wiring and any Sensor A/D or D/A board. It simplifies field wiring by breaking out flat cable to screw terminals.
Thermocouple Reference
A temperature sensor on the 7409TB supplies a dedicated ninth channel with a measure of the temperature at the cold end of thermocouples. 7409TB boards may be painlessly interchanged because each cold-junction sensor is individually calibrated.
Field Connections
Five screw terminals are available for each channel: two for voltage measurement, two for sensor excitation, and one for a shield. Field wires need only be stripped of insulation, inserted into the terminal receptacles, and the screw tightened for a secure connection. A 40-pin header on the back side of the board facilitates panel mounting.
Mechanical
The board is rigidly constructed from 1/8-inch thick FR-4 material to prevent flexing caused by heavy gauge field wires.
