X-420™

Web-Enabled Instrumentation-Grade Data Acquisition

4 Analog-to-Digital Inputs, 2 Digital I/O, up to 16 1-Wire Sensors (temp/humidity), Frequency Input

PRODUCT OVERVIEW

The X-420TM is a multifunction web-enabled
industrial control and instrumentation
module. The X-420 has four multi­function analog inputs, two digital I/O
with programmable pull resistors, two
pulse counters, one frequency input, 16
general purpose timers, 16 general purpose
registers, and a 1-Wire® bus. The 1-Wire bus
supports up to 16 sensors for monitoring
temperature, humidity and more. It can be
controlled and/or monitored over any TCP/
IP network including private networks, IP­based industrial control networks, and the
Internet. Users can operate the X-420 using
a web browser, the CBW Mobile app, or
custom applications written for a computer,
PLC, or other automation controller.

The X-420’s built-in interface allows you

to create custom “Tasks” for simple and
advanced control logic. Easily create tasks based on time, input or outputs’
status, or device responsiveness. The X-420 also has a built-in BASIC
interpreter for custom applications not achievable through the Task
Builder system.

The module is powered by an external wall transformer (9-28 VDC), solar
panel, or other DC power source. The model X-420-E is powered over the
twisted pair Ethernet cable.

Other features are also included such as, email notication, event
scheduling, and logging. The X-420 can control and monitor up to 32
remote devices, graph logged data, FTP logged data, email logged data,
send encrypted emails, and monitor its power supply voltage. The X-420
supports a number of Ethernet protocols including HTTP/HTTPS, Modbus/
TCP, SNMP V1,V2 & V3, NTP, SMTP(Encrypted), and FTP/FTPS. The status of
the device can be retrieved in human readable formats XML and JSON.

The X-420 supports TLS V1.2 encryption as well as cloud integration(not
required) for easier conguration and access. Specically the X-420
supports HTTPS connections, can send encrypted emails, can
communicate with remote devices using TLS, and send logged data
to FTP servers over an encrypted connection. In addition, the X-420
can be congured to automatically connect to ControlByWeb.cloud,
ControlByWeb’s cloud service. This feature is not required, but does
simplify the conguration process and internet access to an X-420
installed behind a network router by eliminating manual conguration of
the device and port forwarding setup on routers.

Features:

º Built-in web server for conguration and remote

monitoring (HTTPS supported).

º Four channel, programmable, 16-bit, analog data

acquisition system.

º Two 5V digital input/outputs. Use as inputs to monitor

wind speed or rainfall etc. Use as outputs to control
relays or other devices.

º Two pulse counters.

º Millivolt AC frequency input for use with magnetic or

optical wind speed sensors

º 1-Wire port for connecting up to 16 digital sensors for

measuring temperature, humidity and more.

º 1-Wire temperature sensors are available in various

packaging and accuracy.

º Sensor/Input status can control I/O on other

ControlByWeb devices.

º Control/Logic Task Builder for custom control with no

scripting necessary.

º Congurable logging of all I/O, both local and remote.

º Real-time clock with manual or NTP time sync.

º Send email alerts (up to 8 email addresses) based on any

sensor or input conditions.

º Send encrypted emails.

º Auxiliary protocols including: Modbus/TCP, SNMP V1,V2

& V3, and Remote Services.

º Custom scripts using the built-in BASIC interpreter

provide additional exibility.

º Ethernet auto-negotiation automatically selects speed,

duplex mode and works with straight or crossover
cables.

º Simple and easy to use.

º Power Supply: 9 to 28VDC and/or POE

º 5-year warranty.
