Rune polytronics supplies a range of electronic process control instruments and systems. The dedicated logic controller is an economical alternative to plc + mmi which can perform almost all minimum required functions of a plc. The front facia has a bright 5-digit 7-segment red led display, which can be used to indicate process value/timing/ counter reading as well as fault codes. The unit is micro-controller based and hence with little modifications in software, it can be used to perform different applications at very less changeover time. Standard features include 8 digital inputs/outputs, potential-free relay contacts, 5 large membrane key switches for data entry/function keys, and status indicating leds. Input/output expandability is an added advantage. Optionally analogue inputs or high-speed inputs can be configured. Also optional serial pc interface. Technical specifications: operating voltage-240 v ac ±10%, 50 hz; inputs- non-isolated inputs with diode protection, optional opto isolated inputs; outputs-relay contacts rated for current 5 amp, 240 v ac resistive load; time accuracy- ± l msec, typical; power consumption-20 w max; dimensions-panel mounting type, size 144 x 72 x 200 mm. Areas of use are blister forming machines, vacuum forming, machines, pad printing machines, synchronisation of two machines, auger [screw dispenser] controller, food processing, etc.
