Optical
Isolator Module |
|
This DIN rail
mounted encoder interface lets you connect an encoder to a variety
of controllers, or to multiple input devices. It provides an
optically isolated signal and is available with one of four output
driver options making it compatible with all major counter, drive
and PLC components. Multiple modules can be daisy-chained together
and drive as many as eight different devices from a single encoder.
The interface module also provides LED output indicators for two quadrature
channels and an index. All circuitry for the module is packaged in a housing
that mounts to a standard external DIN rail. For ease of installation, a 75
mm length of DIN rail is supplied with each module.

Intrinsic
Safety Barrier |
|
This Galvanically
Isolated Intrinsic Safety Barrier is the perfect complement to
BEI encoders for hazardous environments. It is electrically compatible
with all popular counters, PLCs and controllers, and it features
isolation for power and three signal channels, as well as LED
indicators for power and data - all in a single DIN rail package.
The BEI Barrier
carries CENELEC, UL and cUL ratings and is suitable for long
cable runs. Since it also carries a nonincendive designation
per the National Electrical Code, it can be mounted in Class
I, Division 2 areas.

Dual Encoder to USB Converter |
|
This module can handle signals from two SSI absolute encoders or two quadrature encoders and translates the encoder position to industry standard USB 2.0 format. For SSI absolute encoders, the module can be programmed through the USB interface for number of bits, clock speed and position offeset. For incremental encoders, count mode (X1, X2, X4), reset, preset, and preset/reset on index are programmable through the USB input. Optional programmable data sample function allows module to automatically capture readings on an accurate time clock. USB command sets and communication protocol information is detailed in the PDF link below.

Four Encoder to USB Converter |
 |
The Encoder Converter translates encoder data to industry standard USB 2.0 format that can be read by a computer. The module's four available channels are factory configured for SSI absolute encoders and/or quadrature incremental encoders, in any combination totaling four encoders. USB command sets and communication protocol information is detailed in the PDF link below.

Encoder
Tester |
|
This
DIN rail mounted tester is designed to simply and reliably test the operation
of any industrial encoder. The tester provides LED output indicators
for two quadrature channels and an index as an aid in troubleshooting
and equipment set-up. It can be used for field troubleshooting,
incoming inspection, and to check the operation of encoded motors.
It comes with an instruction booklet that includes connection
diagrams for all the common encoder output types and voltages.
Circuitry for
the Tester is packed in a standard housing that mounts to an
external DIN rail type EN 50 022. For ease of installation, a
length of DIN rail is supplied with each Tester.

Anti-Dither
Module |
|
This
module can solve the problem of extra counts caused by high vibration. The
Anti-Dither module accepts quadrature inputs (A and B signals)
and sends a single channel signal to the counter circuitry only
when there has been true movement of the encoder. This is especially
useful in web processes, handling and inspection systems that
use conveyors and simple speed or position control in high vibration
environments.

Encoder Broadcaster
Module |
|
The
Broadcaster accepts standard incremental encoder inputs,
(two channels in quadrature plus an index and complements)
and can broadcast up to four encoder signals to four independent
devices. Each of the broadcast signals is optically isolated
eliminating ground loops. This compact package also allows
for signal processing options, such as anti-dither filter,
integer countdown or pulse and direction outputs, to be incorporated
into each of the four broadcast signals independently. The
broadcaster is ideal for driving multiple receivers from a
single encoder in applications like electronic line shafting
or synchronization of multiple devices to a single operation.
The module accepts signals from
5 to 28 VDC and provides three output options: Vout = Vin, Vout
= 5 V or NPN open collector. The compact package mounts
to standard EN 50 022 35mm X 7.5mm DIN rail and is 142mm wide,
78mm deep and 45mm above the DIN rail. A 155mm section
of DIN rail is included.

Serial-to-Parallel
Converter |
|
BEI’S serial-to-parallel converter module takes serial data
from any BEI Serial Synchronous Interface (S3) or RS-422 Interface
(S1) encoders and converts it to a parallel output. This
eliminates the high cost and noise susceptibility of long, parallel
cable runs, enabling the simplicity of a serial output encoder
and a low cost twisted pair cable to interface with a standard
PLC or controller. The bright LED indicators give visual
status for deserialization, testing and troubleshooting.
Serial input, either SSI or RS-422
is easily selectable by a Format Select terminal directly on
the board. In SSI mode, the on-board
clock generates pulses to signal the encoder to provide data. Data
is received serially and converted to a parallel format. Clock
frequency is selectable by a Speed Select terminal, again directly
on the board. For 100 feet or less, the 1.25 MHz mode can
be used and for longer distances, up to 500 feet, a 200 kHz rate
is available.
In RS-422 mode, data is received
asynchronously from the encoder and converted to a parallel format.
Speed Select input is used to set the baud rate: 19.2 kBaud for
most applications, up to 500 feet; 115.2 kBaud for shorter runs
below 100 feet.

Power Supplies |
|
More power in a compact, easy- to-install package.
Available in either a 5 volt or a 24 volt version, this supply can deliver 4 Amps (at 5V) or 1.5 Amps (at 24V) to get you that extra bit of power that you need. With a wide range of acceptable input voltages, anything from 85 to 264 VAC (45 to 65 Hz) or 110 to 350 VDC, it's usable in virtually all industrial applications. Transient surge protection is built-in to reduce faults caused by ESD, power-up transients or phase errors. It also has 100% reserve capacity for startup or overload conditions.
