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.
