Communication interface PD3221

fieldbusanalog

The module contains 6 digital input channels, (4 of which can be configured as digital outputs) 2 analog input channels and 1 analog output channel, which can be connected directly to 24 V DC equipment. Furthermore the module contains a PID-regulator, an internal user programmable Calculator channel for local control and a pulse processor. The pulse processor can be used to detect and control fast digital signals (up to 200 kHz) on the modules digital channels, e.g. for controlling a step motor or a machine. Supply voltage: 24 V DC. * 2 Analogue Input Channels * 1 Analogue Output Channel * 6 Digital Input/Output Channels * PID Controller * Programmable Calculator * Programmable Pulse Processor * Continuous Selftest * Overload Protection * P-NET Fieldbus Communication * Watchdog Timer * DIN rail Mounting * EMC approved (89/336/EEC) The PD 3221 UPI module is one of a collection of distributed process control units, intended for use within the P-NET fieldbus system. It provides a versatile interface between a variety of digital and analogue process elements, such as valves, switches, pulses, lamps, alarms, motors, flowmeters, level detectors, temperature, pressure and flow transducers, etc. and distributed master control computers. Its great advantage as part of a distributed network, is that of processing the ability to operate in a local environment involving both digital and analog functions. The unit provides internal conversion of measurements into any engineering units, representing both the digital and analogue processes being monitored and controlled, for direct interrogation by central control and for display on one or more network controllers
