IMO's iSmart intelligent relay range includes models that can support up
to 44 inputs and outputs rated at 8A - sufficient to drive a 1/3hp motor
directly. The twin integral 2kHz counters make these devices suitable for
position control, while a PWM output enables them to control stepper
motors or servomotor speed. The programmable iSmarts also feature a
four-line, 12-character display that can be used as an HMI. Messages can
be displayed relating to preset and actual values, timers, counters,
analogu values or real time clock.
