Digital I/O module PD850

HART4 digital inputscurrent

Multifunction I/O, Digital Source I/Os for nominal 24 volt, Analogue I/Os for 4-20 mA signals, P-NET via Light-Link, Programmable in COPP • Digital Source I/Os for nominal 24 volt • Analogue I/Os for 4-20 mA signals • HART communication interface • Relay outputs • Programmable in COPP • P-NET via Light-Link • Built in input and output functions • Load current measurement • Overload/Underload protection and Alarming • Line Check • Advanced internal self testing • LED for power On and Error indication • Wide Power Supply range • Wide Temperature range • Low Power Consumption PD 850 is a device in the M100 series with both digital and analogue channels. The device offers 16 channels as interface for various types of process signals, valves, pumps, level detectors, temperature and pressure transducers etc. The 16 channels consist of: • 4 digital inputs/outputs. • 5 digital inputs, of witch one channel can operate as fast digital input. • 3 analogue inputs/outputs, all with HART interface • 4 relay outputs Digital inputs can be configured to perform Line Check. The Line Check function can be used in relation to two-wire proximity switches. In case of error the hardware will report either ‘Line open’ or ‘Line short-circuited’ respectively.
