NI-9861 Specifications
Definitions
Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.
Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.
- Typical specifications describe the performance met by a majority of models.
- Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.
Specifications are Typical unless otherwise noted.
Conditions
Specifications are valid for the range -40 °C to 70 °C unless otherwise noted.
Low-Speed/Fault Tolerant CAN Characteristics
Transceiver | NXT TJA 1054AT |
Max baud rate | 125 Kbps |
CAN_H, CAN_L bus lines voltage | -27 to +40 VDC |
CAN Supply voltage range (VSUP) | +9 to +30 VDC |
MTBF | Contact NI for Bellcore MTBF specifications at other temperatures or for MIL-HDBK-217F specifications. |
Safety Voltages
Connect only voltages that are within the following limits:
| |||||||||||
External power supply (Vsup) | +9 V DC to +30 V DC | ||||||||||
|
Measurement Category
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.
Power Requirements
Power consumption from chassis | 1 W maximum (active mode) |
Thermal dissipation (at 70 °C) | 1.25 W maximum (active mode) |
