CPD8381: GENERAL DESCRIPTION

The CPD8381 is an ultracompact PLC with 20 I/O points, 8 digital input, 3 analogical input, 8 PNP digital output (two groups of 4 for two other layers of output voltage) and an analogical output.The PLC is also equipped by two auxiliary output, for power supply of external equipment, with the same voltage of PLC power supply and 5V stabilized. The CPD 8381 is equipped with sofware filter for input both digital and analogic, 40 Timers, 20 Counters and a fast timer settable in msec. The comunication with other device, such as the PC, keyboard, is guarantee by two RS485 sockets half/full-duplex, usable also for programming.
