CPU modules with 10, 16 and 24 I/Os are suitable for battery powered applications such as vehicles, traffic signals, access alarms and solar powered remote sites.
Three new additions to the Pentra PLC range comprise CPU modules with 10, 16 and 24 I/Os that are capable of being powered from a 12V DC supply (10.2-18V range).
This makes them suitable for battery powered applications such as vehicles, traffic signals, access alarms and solar powered remote sites.
The Pentra range has double the memory size of the Idec MicroSmart PLC, more processing speed and the capability of floating point maths meaning the Pentra can handle most complex tasks that are thrown at it.
The CPU has high speed counter inputs counting at a maximum frequency of 50kHz with 32bit word comparisons and instruction calculations, also PID with an advanced auto tune feature.
One serial port is fitted as standard with the capability to add a second, either RS232C or RS485 giving access to bar code readers, printers, displays etc.
Modem communication, Datalink (Idec's own network) and Modbus master/slave communication is also possible via this port.
The upgraded programming software, WindLDR V5.0, gives the user the options of online editing and runtime programme downloading which means the Pentra does not have to stop its scan while programming modifications are undertaken.
If the user wants to develop a program and the PLC is not available for testing, then he or she can use the program simulation feature directly on the PC.
