Relays aim for for position control applications

An IMO Precision Controls product story
Edited by the Engineeringtalk editorial team Nov 23, 2004

iSmart intelligent relays feature enhanced memories, inbuilt high-speed counters and a pulsewidth-modulated output that makes them ideal for position control applications.

Leading supplier of industrial automation and electronic control components, IMO precision controls, is launching a new series of low cost "intelligent relays".

The iSmart range has enhanced memory provision, built in high-speed counters and a pulsewidth-modulated output that makes the series ideal for position control applications.

The iSmart range includes devices that can support up to 44 inputs and outputs rated at 8A, sufficient to drive a 250W motor directly.

The devices have twin integral 2kHz counters that make iSmart ideal for position control, and when used with the pulsewidth-modulated output make iSmart an unbeatable proposition for controlling stepper motors or servomotor speed.

They can be used with a blind controller, or come with an integral programmer that can be programmed using relay ladders or function block diagrams (FBDs).

The devices have an enhanced memory capacity sufficient to store up to 200 lines or 800 relay ladder instructions, or 99 blocks of FBD.

The included programming software, compatible with Windows 98, 2000, XP and CE systems, offers powerful simulation functionality, enabling a program to be tested remotely on desk-based or portable PCs.

Online monitoring is also available.

Programmable iSmarts also include a 4 x 12 character display that can be used as an HMI.

Messages can be displayed relating to preset and actual values, timers, counters, analogue values or real time clock (RTC), which can be used for accurately controlling processes over seconds, minutes, hours, days, months or years.

There is an option of a memory module and a communications interface to a high speed datalink enabling remote I/O or up to eight iSmarts to be linked.

Communication can be through Modbus or Fieldbus, using Ethernet, Profibus, DP Slave, DeviceNet, ASI or Lonworks.

Operation is possible in languages including English, German, French, Italian, Spanish, Portuguese and Chinese.

The new range conforms to CE, UL and C-UL standards.
