OPT-SNAP-IDC5Q

SNAP-IDC5Q SNAP 2-Axis Quadrature Position Input Module

The SNAP-IDC5Q quadrature input module is designed to allow a SNAP brain to resolve two axes of rotating position
information from quadrature encoder devices. The module outputs a pulse to the brain upon each change in quadrature
state. The brain counts the module output pulses and keeps track of the direction and position.
 
The SNAP-IDC5Q is used with SNAP-PAC-EB1 brains and SNAP-PAC-R1 controllers. The module is also fully compatible
with legacy SNAP-B3000-ENET and SNAP-UP1-ADS brains, as well as B3000 and B3000-HA brains using the mistic
protocol.
 
The SNAP-IDC5Q can be used with most quadrature devices, including transducers with TTL, CMOS, and open collector
outputs. All inputs are isolated from each other and do not share any common connections.
 
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP-PAC-EB1 brain or a SNAP-PAC-R1
controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-
based control or for use as intelligent remote I/O for an Allen-Bradley MicroLogix or other RSLogix-based PLC system,
such as ControlLogix or CompactLogix.

* The SNAP-IDC5Q supports an encoder input frequency of 25 kHz. However, legacy I/O brains have limited quadrature counting capability. The following limits apply to them: 2.5 kHz for SNAP-B3000-ENET brains 4 kHz for SNAP-UP1-ADS brains 5 kHz for other legacy brains with high-speed counting
