Page 6: Description
DESCRIPTION The system provides segment current capacity in 250mA increments, up to 500mA, and then offers redundancy with the provision of an additional 250mA module, which is connected in a load-sharing manner, to achieve an N+1 type of configuration. Each 919x-FP module will support 4 segments, so two “groups” of modules are required to support 8-segments. - Page 7 Plus * This dimension applies if the F809F-Plus diagnostic module is not used.

Page 8: Alarms
Power A – Power B – Figure 2 .3 - Power distribution to modules 2 .3 Alarms Each 919x-FP module monitors the output of the four fieldbus segments and indicates an alarm (by means of a built-in, normally-closed relay) if any of the segments is shorted, or its output falls below the ‘minimum output voltage threshold’. -
Page 9: Systems And Components
The input power, field segment and alarm wiring connections are available with the option of either pluggable screw terminals (9189-CA-PS) or pluggable spring-clamp terminals (9189-CA-PC). The pluggable connections are screw-retained providing a reliable connection in an industrial environment. SYSTEMS AND COMPONENTS The system and component part numbers and their descriptions are given here. -
Page 10: Mechanical
MECHANICAL 4 .1 Mounting Orientation The optimum orientation for the 9189-CA-P* carrier is mounted on a vertical surface using a horizontally aligned DIN-rail, or surface mounted in the same orientation - see Figure 4.1. This method of mounting ensures optimum heat dissipation from the 919x- FP Power Supply Modules, and an operating temperature range of –20°C to +60°C. -
Page 11: Din-Rail Mounting Option
4 .3 DIN-rail mounting option The carrier is designed for mounting on 35mm x 7 .5mm T-section “top hat” DIN rail to EN50022 and uses four built-in DIN clamp tabs to hold it on the rail. 4 .3 .1 To mount on DIN rail The power modules at each end of the carrier must be removed to obtain access to the DIN-rail clamp screws. - Page 12 NOTE The carrier hangs on the fixings and so there must be a minimum of 10mm top clearance above the carrier to enable it to be located over the screw heads before it is lowered onto the M4 fixings. 43.4 200 TYP.(H) TOP clearance when mounted Horizontally.
