  • Cold-junction compensation for thermocouples
  • Each channel configurable for any supported sensor type
  • Fully electronic calibration

Model 417 is a legacy product and is not recommended for new designs. Legacy products are available but may have lead times up to 12 weeks and minimum order requirements. Use our Product Finder to find a comparable product or contact our Design Support Team.

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 different sensor type. Analog-to-digital conversion is performed in under 22 milliseconds per channel. Thirty-two channels are scanned in 640 milliseconds.

The 417 board plugs directly into any ISA bus slot. Linearization, calibration, and sensor type are software programmable, eliminating trim potentiometers and the need for board access. Sensor field wiring is accomplished 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 stored in EEPROM so the boards may be easily interchanged.
