Product Manual Excerpt

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. The data presented to the processor can be configured as: • Engineering Units • Scaled-for-PID • 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. Hardware Features The module fits into any slot, except the processor slot (0), in either an SLC 500 modular system or an SLC 500 fixed system expansion chassis (1746-A2). The module contains a removable terminal block, providing connection for 16 analog input channels, which are specifically designed to interface with analog current and voltage input signals. The channels can only be wired as single-ended inputs. There are no output channels on the module. The module is configured via the user program. The following graphic displays the main hardware features.
