Description
The product with the Part Number 782079-01 is known as the NI-9757. It is designed to be compatible with Bosch LSU 4.2 or LSU 4.9 wideband, and differential narrowband oxygen sensors. This module is versatile in its measurement capabilities, providing outputs for A/F, F/A, Lambda, and Phi.
One notable feature of the NI-9757 is its fuse-protected heater control circuits, enhancing the safety and durability of the module. The maximum output stack is determined by the maximum switching frequency or output stack, ensuring flexibility in application.
It operates within a power supply voltage range of 6 V to 32 V, with an operational voltage range for LSU 4.x sensors set between 8 V and 16.5 V. This wide range allows for versatile usage in different power environments. Additionally, the module includes a battery protection feature, switch battery protected to -18 V, safeguarding against potential power issues.
The current consumption without sensors is maximized at 100 mA, ensuring efficient energy usage. Lastly, the sensor heater power requirement can support up to 12 A for all channels, accommodating substantial power needs for heating sensors.
