Introduction

Altech Smart Relay provides the right solution for all your control needs!

Providing excellent performance and functionality, Altech Smart Relay performs simple logic, timing, counting, and real time clock
operations. It is an ideal programmable controller for simple control applications such as building construction equipments, HVAC, parking
lot lighting and other applications in which cost is a primary design issue. All programming and data adjustments can be done via the on-board
keypad and display or with the help of a software.

Programming Altech Smart Relay with the help of ASR-Soft configuration software is quite simple, without particular programming
knowledge. It facilitates program generation, project simulation and documentation which are accomplished simply using the pick and place
functionality, allowing maximum ease of operation.

Some of its features are:

Ÿ Integrated, ready to use, wide range of programmable functions including 16 timers, 16 (retentive

selectable) counters, 16 time switches, 16 compare counters, 16 soft text messages, 64
auxiliary relays and 12 analog comparators.

Ÿ 8 digital inputs & 4 relay outputs . Two analog inputs (0 -10V) in 12 -24VDC, model which can be

used as digital inputs.

Ÿ Ability to add up to three(3) extension modules expanding I/O’s to 32 digital inputs, 16 relay outputs.

Ÿ Communication module allows programmable relay to be connected to a Modbus network through

RS 485 link

Ÿ Backlit LCD screen for display and modification of pre-selected parameters of function blocks,

viewing I/O status and programming on the device .

Ÿ Ladder programming using software on PC as well on the device with the help of keypad & LCD Display

Ÿ Memory back up allowing programs to be transferred or copied into another Altech Smart Relay with the

help of a memory card.

Ÿ Compact size –only 72mm (2-53/64") wide x 90mm(3-35/64”) high x 65 mm (2-9/16) deep, reducing

panel area requirements for lower installed costs.

Ÿ Soft keys for convenient creation and editing of programs on the device.

Ÿ Available in both: AC(110 - 240 VAC) & DC(12 - 24 VDC) models.

Ÿ Password & Parameter lock facility.

Base Module

EXTENSION MODULE

Ÿ Extension Module can be used with base module to increase I/O capacity of Altech Smart Relay.

Ÿ Every extension module has 8 digital inputs & 4 digital outputs.

Ÿ Connections are made in Daisy chain fashion.

Ÿ Altech Smart Relay can be expanded by connecting 3 extension modules, to obtain a maximum

configuration of 32 inputs and 16 outputs.

COMMUNICATION MODULE RS 485

Ÿ RS 485 provides Modbus communication for Altech Smart Relay.

Ÿ Possible to connect multiple Altech Smart Relay’s with a SCADA system or a HMI over RS 485.

Ÿ Available in both AC (110 - 240 VAC ) & DC (12 - 24 VDC) models.

FRONT VIEW OF KEYPAD & FUNCTIONS OF KEYS

The 8 keys located on the front facia of Altech Smart Relay are used to configure, program and control the
application.

DEL

This key is used to delete a program element or a blank line, if the cursor is located at the extreme column.

Extension

Selection switch

ALT

This key is used for selecting/exiting a parameter in the edit mode and to show either the Parameters or Program
while the program is running. This feature is also useful for debugging.

OK

This key to is used to insert a program line, when cursor is blinking in the first column of first row. During the
parameter entry while editing this key saves the changes and proceeds to next parameter. In RUN mode, this key
can be used to select one of the 3 displays. This also selects/deselects links.

ESC

This key is used to exit the menu or a selection. During the parameter entry it proceeds to the next parameter without saving the changes.

Z (ARROW) Keys

On the program editor screen, the arrow keys are used to move up, left, down and right. The position on screen is shown by a cursor or
blinking text. They are used as push buttons to get signals from user. If user goes into PAR (parameter mode), then these keys are not
available as z-keys. At that time these keys are used as arrow keys.

Power Supply Wiring

1. Although the Altech Smart Relay has been designed to withstand the negative effects of any electrical noise that might be present in the incoming power supply it may
be necessary to insert an isolation transformer between the supply and the line terminals of the Altech Smart Relay.

2. While using the DC Altech Smart Relay, run the 24 VDC Input line away from the 100 V AC and 200 V AC lines.

Wiring of Input/Ouput

1. Separate the Input lines and output.

2. When the output lines are running close to power supply lines or the Input lines use batch shielded and ground them.

TRANSFER

The TRANSFER function allows data to be transferred from Memory Card to
Altech Smart Relay or vice-versa.
Transferring data to memory card is useful when user wants to load the same
program in many Altech Smart Relay units. In this case instead of using PC user can
make use of memory card, which is capable of storing one program. This feature is
particularly useful on the production line where user is not required to edit and
debug the program and a PC is not available.

In this mode of transfer "PASSWORD"and "UTILITIES"such as Backlight
configuration & Extension module state will also get transferred with the program
ladder.

Programming using the ASR-Soft

ASR-Soft is the exclusive Windows based programming software for the Altech Smart Relay . It facilitates:

Entering the Program: Select & Place

ASR-Soft provides a user-friendly interface wherein the user has to only select contact type and contact
number and place it where it is required. Contacts get connected automatically if they are on the same line.
User can enter comments for better readability and for future reference .

Saving Programs

ASR-Soft allows user to save individual programs on the PC.

Debugging

ASR-Soft is very powerful in error handling. It displays any possible errors as the program is being entered
to make corrections simultaneously.

Simulation on PC

User can simulate the program on PC. User can use buttons provided on the screen to simulate the input
connections. Scroll bar can be used to simulate Analog input. The actuation/ de-actuation of the relays can
be monitored on the screen.

Simulation on Altech Smart Relay

User can connect the Altech Smart Relay unit to PC using a serial Communication cable / USB cable and perform on line program simulation. In this mode the PC acts as a
master and the inputs are taken from Altech Smart Relay and outputs are sent to Altech Smart Relay unit (and the extension modules, if connected). This mode is useful in
debugging the entire system since the actual I/Os are used.

Printing

User can take print outs of programs in two different formats, namely Short format and Detail format. Also, program Parameters and Comments can be printed.

Transfering Programs

Programs can be transferred from PC to Altech Smart Relay and vice versa using serial Communication cable / USB cable. This saves the program entering time on the Smart

Transfering Clock

With this utility user can set the clock (date and time) on the Altech Smart Relay.

Error Window

Select File -> New from the menu bar to create a new program.
A blank screen will appear. Now you can start entering the program. Ensure that you have chosen proper Altech Smart Relay Configuration before starting the program entry.

Choosing Contact Type

Position the cursor at the place where you want to insert the contact by a left click with mouse. The position will get highlighted. Choose the required contact type and Contact
Number from I/O function selector. Click on the required contact and contact number, which will be highlighted for a few seconds. The selected contact will appear at the
position selected in the program. The selected contact number will be shown with a tick mark to indicate that it has been used in the program. You can right click on any of the
contact to change its type and properties.

Connecting Inputs & Outputs

Each circuit connection runs from left to right. Please remember this when you interconnect contacts and relay coils. User can draw a circuit connection horizontally from left
to right and vertically between adjacent circuit connections. An intersection of circuit connections represents an electrical connection.

Horizontal connection

To make a horizontal connection, click on the horizontal dotted line in the connection box of the circuit. Or to make connection in contact box, press right button and select
"Joining link". Generally when an output coil is placed in the fourth column, it gets automatically connected.

Vertical connection

To make a vertical connection click on the vertical dotted line in the connection box of the circuit. Vertical connection represents OR connection. For deleting a connection
just left click on the connection line.
