Industrial repeater

opticalCAN busATEX

This device provides a repeater function between three CAN-bus segments. The first one connects via a DIN-rail mounted T-bus or via an ordinary 5-way terminal block and provides power for the logic core and the second segment. The optional second segment connects via fibre-optical cable with ST connections. The third segment is a normal 'copper' CAN-bus with ATEX intrinsic safe isolation and safety parameters. This allows for installing interfaces and sensors inside 'Zone 2 or zone 22' potentially explosive environments. Functionality Two- or three-way CAN-bus repeater Bus connection for main power + CAN-bus up to 1Mbps Intrinsic safe CAN-bus connection (needs power from the hazardous side) Optional fibre-optic CAN-bus link Specifications Voltage range 12-36VDC Instrinsic safety isolation ≥ 0.5mm Allowed isolation voltage up to 1kVrms/1414Vpeak (non-ATEX) Bus powered Um 6-36VDC, power <100mW 5-Way 3.5mm pluggable screw terminal connections for safe side Optional 820nm 'ST' fibre-optic multimode coupling to other repeater device Propagation delay 100ns, equivalent to ~20m of cable length DIN-rail enclosure 101x80, width 17.5mm CAN-bus connection via DIN-rail mounted T-Bus connector or via 5-way 3.81mm terminal block
