Description

The Sensoray Models 419 offer a cost-effective way to acquire sensor data for any ISA bus system. They features 16-bit resolution from 16 channels, each individually programmable for a different sensor type. Analog-to-digital conversion is performed in under 22 milliseconds, providing 45 channels per second scan rate.

The 419 adapters plug directly into any half slot ISA computer. Linearization, calibration, and sensitivity are software program- mable, 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 model 7409TDIN with DIN rail mounting hardware.

Calibration
Models 419 automatically self- calibrate by measuring internal precision references. Reference data is stored in EEPROM so the adapter boards may be easily interchanged. Signal conditioning is provided for thermistors, RTD’s, thermocouples, strain and pressure, resistance and voltage inputs. Standard correction for nonlinear sensors is built in. Custom compensation can be down loaded.

Excitation
A pulsed constant-voltage source is provided for strain and pressure sensors. A pulsed constant-current source is provided for resistive sensors. Lead loss errors from RTD’s, thermistors, and resistors are eliminated with the use of a four-wire circuit.

An on-board microprocessor continually scans the active sensor channels. Each channel is amplified, digitized, filtered, converted to engineering units, and stored in on-board memory. This process is independent of host CPU activity.
