Description
The Micro Motion model 505 is a DIN rail mount IS Barrier and signal isolator, meant to supply intrinsically safe
power to the model 2200S Micro Motion Coriolis Transmitter (Reference BVS 08 ATEX E **** X) which can be
connected to any Micro Motion Coriolis Flow Sensor. The model 505 also provides three port galvanic isolation as
well as transmitting process variables to the Safe area side via 12-20mA input loop current signaling and HART
communication. The 12-20mA signal from the Hazardous area (field) side is level shifted to 4-20mA on the Safe area
(host) side.
The model 505 has three sets of screw terminals: On the Hazardous area side, Loop Supply/mA/HART input. On the
Safe area side, 18-42VDC power input and mA output/HART signaling. Hazardous area side and Safe area side are
located on opposite sides of the model 505 plastic cabinet with more than 50mm between them.
