Pluto is a cost effective, powerful and compact safety PLC for all
machine safety applications. Most safety devices on the market
can be connected directly to Pluto and multiple safety sensors
can be connected to a single input and still achieve the highest
safety level. Programming is done easily in the accompanying
software Pluto Manager.
Pluto is available in different models; simple models for smaller
systems and models with bus communication for larger systems.
Models with analogue inputs are available as well.
Main benefits
• Easy programming and still powerful
• Eliminates the need for extra module for speed monitoring for ex.
• Up to 32 Pluto can exchange data without extra programming
• Safe bus simplifies connection between cabinets in accordance with PL e/SIL3
• Extensive communication possibilities with HMI and PLCs
Main features
• Most Machine Safety functions inclusive speed monitoring and analog input monitoring
• Advanced programming possibilities
• Ladder and TÜV approved function blocks
• PL e/SIL 3
Features and benefits
• 8 channels for RTD (Pt100. Cu10. Ni100 and Ni120 and resistor) inputs
• 3-wire connection to RTDs
• 14 Bit resolution
• Inputs are monitored for open-circuit, shortcircuit and has a input grounded sensor
The AI830/AI830A RTD Input Module has 8 channels for
measurement of temperature with resistive elements (RTDs). With 3
wire connections. Al the RTDs must be isolated from ground.
The AI830/AI830A can be used with Pt100. Cu10. Ni100. Ni120 or
resistive sensors. Linearization and conversion of the temperature to
Centigrade or Fahrenheit is performed on the module.
Every channel can be individualy configured. The MainsFreq
parameter is used to set mains frequency filter cycle time. This will
give a notch filter at the frequency specified (50 Hz or 60 Hz).
The AO895 Analog Output Module has 8 channels. The module includes
Intrinsic Safety protection components and a HART interface on each
channel for connection to process equipment in hazardous areas without
the need for additional external devices.
Each channel can drive up to 20 mA loop current into a field load such as
an Ex-certified current-to-pressure converter and is limited to 22 mA in
overload conditions. All eight channels are isolated from the ModuleBus
and power supply in one group. Power to the output stages is converted
from the 24 V on the power supply connections.
Features and benefits
• 8 channels of 4…20 mA outputs.
• HART communication.
• 1 group of 8 channels isolated from ground.
• Power to drive Ex certified I/P actuators.
Features and benefits
• 4 channels of -20 mA .+20 mA, 0 .20 mA, 4 .20 mA or -10 V .+10 V, 0 .10 V, 2 .10 V outputs
• Individualy galvanicaly isolated channels
• OSP sets outputs to predetermined state upon error detection.”
The AO820 Analog Output Module has 4 bipolar analog output
channels. The choice of current or voltage output is configurable for
each channel. There are separate sets of terminals for voltage and
current outputs, and it is up to the user to wire outputs properly. The
only differences between current or voltage channel configuration is
in software settings.
To supervise the communication to the A/D-converters the output
data is read back and verified. The opencircuit diagnostics are read
continuously as wel. The process voltage supervision input give
channel error signals if the voltage disappears. The error signal can
be read via the ModuleBus.
The HBS01-CJC the mounting base is for Singular AI03 (8-CH) RTD and AI04 (16-CH)
TC & mV Analog Input modules. The base includes a built-in RTD that can be used
for Cold Junction Compensation.
Two (2) 16-point headers on the base provide connections to either (2) pluggable
16-point terminal blocks for direct connection of field signal wires or to SPK0x_-yy
marshaling cables when field signal wires are landed on 3rd party termination hardware.
Features and benefits
• Termination for up to eight (8) 2/3/4/ wire RTDs or sixteen (16) TC / mV process
signals within a horizontal row.
• All SD I/O modules & bases of all types (Singular or Redundant) AND (Compact or
Full-size), are 100% fully compatible with each other. Thus, Singular & Redundant,
Compact or Full-size I/O modules can be mounted within a single, common HN800 I/O bus.
• Optional mechanical keying can be implemented to prevent insertion of the wrong I/O
module type.
• Latching device on the base locks the base into position on DIN-Rail.
• Industry standard 35-mm DIN rail, Horizontal row mounting.

Are you using a door mounted control panel? Consider this
when choosing options
Consider the dimensions and mounting requirements,
cable sizes and heat losses
Review the control terminal wiring and ensure the cable

document the appropriate communication settings, such
as MAC ID, Device Object Instance ID, Baud, etc.
Are there any analog outputs from the drive that are wired
to another device? If so, document the type of signal (e.g
4-20 mA), where it was terminated on the drive, what it was
used for, and any scaling of the signal.
Are there any relay outputs from the drive that are wired to
another device? If so, document where it was landed on the
drive and what it was used for.
Are there any other control or reference sources that

This guide will help you to replace the ACH550 drive with the
ACH580 HVAC drive. Follow the steps outlined in this guide to
find the optimal replacement product and to expedite the
replacement process.
Step 1: Sizing of the drive and selecting options
Compare power range, mounting methods and dimensions to
select the appropriate ACH580 product compared to the
ACH550 drive, see the checklist items for some useful
guidance.
Step 2: Wiring and parameter setup
Compare electrical data and basic parameter range for optimal
replacement. Use the replacement ACH580 manual to assist
with the commissioning process.
Before beginning, some basic checklist items
All information regarding the control of your application
should be gathered from the ACH550 prior to selecting and
performing the actual replacement, control and parameter
settings should be noted to ensure consistency in the
replacement ACH580.
This checklist covers the main information you may require to
guide you through the replacement process. If the ACH550
cannot be powered, the technician should gather all the
information below that is not parameter related.
