Micro800 Plug-in Modules Chapter 1
Digital Plug-ins
12/24V Digital Plug-ins — 2080-IQ4, 2080-IQ4OB4, 2080-IQ4OV4,
2080-OB4, 2080-OV4
These digital plug-in modules provide transistor outputs for switching a variety
of 12/24V DC voltages to field loads and for detecting 12/24V signals from field
devices.
AC/DC Relay Output Module — 2080-OW4I
The 2080-OW4I is a 4-channel relay output and provides dry contact relay
closure outputs for switching a variety of AC and DC voltages to field loads.
Analog Plug-ins
The following analog plug-ins are supported by most Micro800 controllers.
Non-isolated Unipolar Analog Input and Output — 2080-IF2,
2080-IF4, 2080-OF2
These plug-in modules add extra embedded non-isolated unipolar (0...10V,
0...20 mA) analog I/O and offer 12-bit resolution.
Specialty Plug-ins
Non-isolated Thermocouple and RTD — 2080-TC2 and 2080-RTD2
These non-isolated plug-in modules help to make temperature control possible
when used with PID (Proportional Integral Derivative).
See Non-isolated Thermocouple and RTD Plug-in Modules – 2080-TC2 and
2080-RTD2 on page 19 for more information.
Memory Backup and High Accuracy RTC — 2080-MEMBAK-RTC
and 2080-MEMBAK-RTC2
These plug-in modules allows you to make a backup copy of the project in your
controller, and adds precision real-time clock function without needing to
calibrate or update periodically.
They can also be used to clone/update Micro800 application code. The
2080-MEMBAK-RTC2 has larger memory to support clone/update for
Micro870 application code. However, these plug-in modules cannot be used as
additional Run-Time Program or Data Storage for recipe and datalog.

Project Backup and Restore
The project can be backed up and restored using Connected Components
Workbench software.
Six-channel Trimpot — 2080-TRIMPOT6
This trimpot plug-in offers an affordable method of adding six analog presets for
speed, position and temperature control.
High Speed Counter — 2080-MOT-HSC
This plug-in module provides enhanced high speed counter capabilities to the
Micro800 controller. It supports the same functionalities of an embedded HSC
on the Micro800 controllers but is enhanced to support up to 250 KHz 5V
differential line driver for improved noise immunity and provides additional
dedicated I/O.
For more information, see High Speed Counter – 2080-MOT-HSC on page 25.
Communication Plug-ins
RS232/RS485 Isolated Serial Port — 2080-SERIALISOL
The 2080-SERIALISOL plug-in supports CIP Serial (RS-232 only), Modbus
RTU (RS232 and RS485), and ASCII (RS232 and RS485(1)) protocols. Unlike
the embedded Micro800 serial port, this port is electrically isolated, making it
ideal for connecting to noisy devices, such as variable frequency and servo drives,

Micro800 Plug-in Modules Chapter 1
as well as for communications over long cable lengths. Depending on the
application and baud rate setting, you can extend this length.
DeviceNet Scanner — 2080-DNET20
The Micro800 DeviceNet plug-in module serves as a scanner and client for
explicit messaging to remote devices including I/O and drives, using a proven and
well-accepted fieldbus/network. It also provides better performance than using
serial and Ethernet (EtherNet/IP Class 3) communications.
For more information, see the DeviceNet Plug-in – 2080-DNET20 on page 41.
IMPORTANT
2080-SERIALISOL is suitable for communication over longer cable length
of up to 1000 m using RS485, with up to 19200 bps baud rate.
The electrical characteristics of cable used and good wiring practices are
very critical in achieving reliable communication performance over longer
cable length. A shielded twisted pair RS485 22AWG cable (example:
3106A from Belden) is recommended. Terminate both ends of the cable
with 120 ohm resistance.

1. Position the plug-in module with the terminal block facing the front of the
controller as shown.
2. Snap the module into the module bay.
3. Using a screwdriver, tighten the 10…12 mm (0.39…0.47 in.) M3 self
tapping screw to torque specifications.
See Specifications on page 61 for torque specifications.
Wiring
The following plug-in modules have 12-pin
female terminal blocks:
•2080-IQ4,
•2080-IQ4OB4, 2080-IQ4OV4
•2080-OB4, 2080-OV4, 2080-OW4I
•2080-IF2, 2080-IF4
•2080-TC2, 2080-RTD2
IMPORTANT
Analog I/O performance depends on the application. For better noise
immunity, cable length should ideally be less than 3 m because the plug-
ins are non-isolated. For longer cable length requirements, use the 2085
expansion I/O modules instead.
