NI-9361, 32-Bit, 8-Channel C Series Counter Input Module
783407-02
32-Bit, 8-Channel C Series Counter Input Module - The NI‑9361 is a differential or single-ended input module. With this module, you can expand beyond the four counters in CompactDAQ to reach up to 64 counters per 8‑slot chassis. You can configure each channel to read a single pulse train or combine them to read up to four incremental encoders. You can also directly connect sensors with open-collector or push-pull outputs by using an internal switchable 1 kΩ pull‑up resistor. The NI‑9361 counters can perform encoder position and velocity measurements. You can synchronize the counters with other analog, digital, and counter measurements in your chassis.

Quadrature Incremental Decoder Interface for VMEbus
VME323
The VME323 is an Intelligent Quadrature Incremental Decoder VMEbus Board which can be configured for interfacing quadrature incremental encoders with or without an index channel. In index mode up to sixteen encoders with two quadrature channels and an index channel can be connected, and in non-index mode up to twentyfour encoders with two quadrature channels can be connected. The VME323 operates on two encoder input channels and decodes a pair of out-of phase signals in order to increment or decrement a counter.

P104 Synchro/Resolver Measurement Board
73SD4
NAI’s 73SD4 is a DSP-based, PC104-compliant Synchro/Resolver Measurement Board with six separate, isolated channels. These channels can incorporate up to six Synchro/Resolver-to-Digital Tracking Converters in a stack-through module. Each channel also produces differential incremental encoder (A & B) outputs (with programmable resolution) and a zero-degree marker pulse. Commutation outputs are available for 4-, 6-, or 8-pole brushless DC motors that eliminate the need for Hall Effect sensors, thereby reducing both processor time and bus traffic.

P104 LVDT/RVDT Measurement Board
73LD4
NAI’s 73LD4 is a PC104-compliant LVDT/RVDT Measurement Board with six separate transformer-isolated channels. The channels can incorporate up to six programmable LVDT/RVDT-to-Digital Tracking Converters in a stack-through module. Each channel is programmable for 2-, 3-, or 4-wire inputs that automatically range between 2.0 volts and 28 volts, so there is no need to purchase multiple boards set for specific inputs. Operating frequency between 360 Hz and 10 kHz can be specified. Each channel also produces differential incremental encoder (A & B) outputs with programmable resolution and a zero-degree marker pulse.

Incremental Encoders
Versatile, compact and flexible – Incremental encodersIncremental encoders are used when retention of absolute position upon power loss is not required. These encoders provide information about the position, angle and number of revolutions. The number of lines per revolution determines the resolution. The current position can be determined by counting these pulses from a reference point. Upon activating the machine, a reference run to the reference point is required to determine the absolute position of the encoder.

Absolute Optical Encoder Kit Version
A2K
The A2K absolute encoder is a non-contacting optical rotary position sensor which reports the shaft angle within a 360 deg. range. As opposed to incremental encoders, the A2K reports the absolute position rather than the change in position. When powered up, it does not require a home cycle, even if the shaft was rotated while the power was off. In multi-turn mode, it tracks the position in a 32-bit counter as long as the power supply is maintained. Internally, an infrared LED flashes through a circular bar code onto a linear array sensor. The microcontroller decodes the image into a unique position. All user programmable parameters such as resolution, origin, direction and mode are permanently stored in an internal EEPROM

Counters and Timers
Orbit Controls counters and timers are designed for connection to practically all industrial sensors and pulse sources . They can be used as process monitors to display the process variable to be measured or as process controllers for control and monitoring tasks. The devices display and process pulses and frequencies, as well as quadrature signals from incremental and absolute encoded rotary encoders. In addition to information on the display, the devices also generate data and analog outputs and monitor preselected limit values. The process parameters are entered via the keyboard so that the display is calibrated in the required units and the output signals, serial interfaces and limit values are optimized.

Absolute Encoders
US Digital designs and manufactures absolute encoders in both optical configurations, for the highest possible resolution and accuracy, and magnetic versions for demanding environments. In either case, absolute encoders report a shaft angle within a single 360-degree shaft rotation without stops or gaps. Unlike incremental (sometimes called "relative") encoders, absolute encoders provide true (absolute) shaft position, eliminating the need for a "home" or "zero" cycle after a supply-voltage power cycle.
