Half-size ISA board

Description
The Sensoray Model 417 offers a cost effective way to acquire thermocouple, voltage, or current loop data for any ISA bus computer. It features 16-bit resolution from thirty-two input channels, each individually programmable for a diggerent sensor type. Analog-to-digital conversion is performed in under 22 milliseconds per channel. Thirty-two channels are scanned in 640 milliseconds.

The 4117 board plugs directly into any ISA bus slot. Linearization, calibration, and sensor type aresoftware programmable,

eliminating trim potentiometers and the need for board access. Sensor field wiring is accomplish- ed with a 40-conductor flat cable and remotely mountable screw-

 termination board, either model 7409TB or 7409TDIN with DIN mounting hardware.

Calibration
Model 417 automatically self-calibrates by measuring internal precision references. Reference data is storen in EEPROM so the boards may be easily interchanged.
