Thông số kỹ thuật allen bradley 1746-NI16I:
The module receives and stores digitally converted analog data into its image table for retrieval by all fixed and modular SLC 500 processors.
The modules, 1746-NI16V and 1746-NI16I, support connections for up to 16 voltage or current analog sensors.
The 1746-NI16 is a multi-class (Class 1 or Class 3) single-slot module. Class 1(1) configuration utilizes 8 input words and 8 output words.
Class 3 configuration utilizes 32 input words and 32 output words. Fixed and SLC 5/01 processors can only operate as Class 1. When the module is used in a remote I/O chassis with a 1747-ASB, it can only operate in Class 1 mode. The SLC 5/02, SLC 5/03, SLC 5/04 and SLC 5/05 processors can be configured for either Class 1 or Class 3.
When the module is used in a remote ControlNet™ chassis with a 1747-ACN(R), it can also operate in either Class 1 or Class 3 mode.
Operate the module in Class 3 mode whenever possible.
The 16 high-impedance input channels can be wired as single-ended inputs. The module provides a direct interface to the following input types:
• ±10V dc
• 1 to 5V dc
• 0 to 5V dc
• 0 to 10V dc
• 0 to 20 mA
• 4 to 20 mA
• ±20 mA
• 0 to 1 mA
(1) Requires use of block transfer in a remote configuration. Publication 1746-UM001A-US-P 1-2 Overview
The data presented to the processor can be configured as:
• Engineering Units
• Proportional Counts (-32,768 to +32,767 range)
• Proportional Counts with User Defined Range (Class 3 Only)
• 1746-NI4 Data Format
Each input channel also provides open-circuit, out-of-range, and invalid configuration indication via the LED’s. These conditions are also displayed in the channel status word
