UNI-4LRS Programmable Latching, Sequence & Memory Relay
Programmable latching and sequence relay. The outputs are four individual single pole normally open contacts. The unit is programmed via three front selector switches.
A din rail mounted tri voltage modular latching / sequence relay with a selectable memory option. Outputs are four individual single pole normally open contacts. The unit is programmed via three front selector switches. Switch 1 determines the number of relays in play, switch 2 the function of the latching / sequencing of the relays, switch 3 selects if the memory function is required.
The unit requires a permanent supply to the coil and operation is then achieved by using up to three volt free trigger commands from A1 onto terminals FWD, BCK or RESET. The unit reacts to the leading edge of a trigger input only. If required the trigger input can then be held continuously, if then a leading edge is then seen on any of the other inputs the unit will operate accordingly. A trigger to FWD will cause the unit to switch the relays in a forward manner, whilst a trigger to BCK will cause the unit to step back a position. A RESET trigger will cause the unit to reset back to the first (start) position.
Two LED’s indicate the units operation, a green LED to indicate the connection of a supply voltage. The red LED will predominantly be not illuminated however, every 2 seconds it will blink quickly the number of relays energised.
