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. The board is rigidly constructed from 1/8-inch thick FR-4 material to prevent flexing caused by heavy gauge field wires.
Two 7409TB's are used with 16-channel Smart A/D boards. The 7409TB may also be used with 7405 D/A boards and with the 421 and 7421 multifunction boards.
Compatibility
One Model 7409TB is required for Models 118, 418, 518, 618, 718 and 7418
Two Model 7409TBs are nedded for Models 417, 419, 619, 719, 7419, 7429
