Type DP Master Class I Protocol PROFIBUS DP Communication speed 9.6, 19.2, 93.75, 187.5, 500, 1500, 3000, 6000 or 12000 kbit/s Galvanic isolation Yes Status indicators Run normally green, Fault exceptionally red, the two traffic indicators RTS and Rx/Tx are yellow flashing controlled by the traffic pace. Connector DB9, female Current consumption (from CEX-Bus 24 V DC) 150 mA typical (200 mA max.) Power dissipation 3.6 W typical Key Features • One FOUNDATION Fieldbus port provides a communication speed of 31.25 kbit/s (FF H1) • Transformer isolated • No power consumed from the FF H1 bus • No power is supplied to the FF H1 bus • Simple DIN-rail mounting • Pre-set, two letter Alpha code lock, see Table 4 on page 75, installed in unit base to prevent incorrect mounting of non-compatible components. Description The CI852, connects the FOUNDATION Fieldbus H1 (FF H1) to the AC 800M. The FF H1 has a communication speed of 31.25 kbit/s and is intended for remote connection of field instruments. The CI852 is connected to the bus via a transformer, and as such neither supplies nor consumes bus electrical power. The number of field instruments that can be connected via the CI852 depends on the physical limitations of the FF H1 network, together with any software limitations (refer to the software documentation).
