Murten, Switzerland— SAIA PCD xx7 Series controllers, from SAIA-Burgess Electronics, allows the PLC user to select the technology and price most suitable PLC for any application. The series, based on PCD1 and PCD2 controllers, have a high degree of modularity, including the PCD1 micro-PLC. The standard version, PCD2, has 132 kB. The CPUs offer 16,384 flags, 256 counters, and 256 timers. Each offers a serial user interface alongside the MPI interface. Experience on Simatic controllers can continue to be used; existing STEP7 programs can be transferred without conversion or associated subsequent costs. SAIA-Burgess Electronics AG
