The G4IDC5Q quadrature input module pair is designed to allow a digital mistic 200 multi-function I/O Brick to resolve positional

information from quadrature encoder devices. The module will output a pulse to the Brick each quadrature state changes. The

Brick will count the module outputs and keep track of direction of rotation.

Module Operation

The G4IDC5Q Quadrature Module pair will convert a quadrature signal to a pulse stream which is output on one of the two

logic side outputs. The active output is determined by the direction of rotation of the encoder. One 0.8 microsecond pulse is output

for each change of quadrature state transition. The actual resolution of the position count is 4 times the encoder resolution (pulses

per revolution).

The G4IDC5Q is actually a pair of modules, one of which is labeled “A”, the other “B”. When the signal into the module A leads

the signal into module B, the output will be on module A. When the signal into module B leads the signal into module A, the output

will be on module B.

On a Digital mistic 200 I/O Unit, quadrature input channels must be configured in pairs, with the lower channel number being

even. Therefore the only quadrature pairs allowed are channels 0 & 1, 2 & 3, 4 & 5, 6 & 7, 8 & 9,, 10 & 11, 12 & 13, and 14 & 15.

The positional count will increment when the signal into the odd numbered channel leads the signal into the even numbered

channel. It will decrement when the signal into the even numbered channel leads the signal into the odd numbered channel.

Since the Digital mistic 200 I/O Unit has a maximum input frequency, 50% duty cycle, of 12.5 KHz, as shown in the

specifications below, then:

Maximum Allowable Encoder RPM (at 50% duty cycle) = 12,000 pulses/sec X 60 sec

encoder pulses/rev 1 minute

Products

Opto 22 produces a broad array of reliable, flexible hardware and

software

products for industrial automation, remote monitoring, enterprise

data acquisition, and machine-to-machine (M2M) applications.

SNAP Ethernet Systems

Based on the Internet Protocol (IP), SNAP Ethernet systems offer

flexibility in their network connectivity and in the software applications

they work with. The physical network may be a wired Ethernet network, a

cellular wireless network, or a modem. A wide variety of software

applications can exchange data with SNAP Ethernet systems, including:

• Opto 22’s own ioProject™ suite of control and HMI software

• Manufacturing resource planning (MRP), enterprise management,

and other enterprise systems

• Human-machine interfaces (HMIs)

• Databases

• Email systems

• OPC client software

• Custom applications

• Modbus/TCP software and hardware.

SNAP Ethernet system hardware consists of controllers and I/O units.

Controllers provide central control and data distribution. I/O units provide

local connection to sensors and equipment.

SNAP OEM Systems

Opto 22 SNAP OEM I/O systems are highly configurable, programmable

processors intended for OEMs, IT professionals, and others who need to

use custom software with Opto 22 SNAP I/O modules.

Linux® applications running on these systems

can read and write to analog, simple digital, and serial

I/O points on SNAP I/O modules using easily

implemented file-based operations. Applications can

be developed using several common development

tools and environments, including C or C++, Java,

and shell scripts.

M2M Systems

Machine-to-machine (M2M) systems connect your business computer

systems to the machines, devices, and environments you want to monitor,

control, or collect data from. M2M systems often use wireless cellular

communications to link remote facilities to central systems over the Internet,

or to provide monitoring and control capability via a cellular phone.

Opto 22’s Nvio™ systems include everything you need for M2M—

interface and communications hardware, data service plan, and

Web portal—in one easy-to-use package. Visit nvio.opto22.com for

more information.
