2 Compact I/O Power Supplies and Communication Bus Expansion Cables Features and Benefits Use the 1769-PA2 and 1769-PB2 Expansion Power Supplies to increase your system s capacity for adding I/O modules. Green power available LED on each power supply. The LED provides visible indication the power supply is operating. Power supplies have upper and lower panel mounting tabs, as well as latches for DIN rail mounting. Upper and lower panel mounting tabs and DIN latches allow true front insertion and removal. DIN rail or panel mounting capability meets the needs of a world-wide market. Terminal identification diagrams on each power supply. Terminal Fuse Cover NOT USED NOT USED +24V dc dc NEUTRAL CHASSIS DANGER: Do not disconnect while circuit is live unless area is known to be non-hazardous. identification diagrams are located on each power supply, making terminal identification easier. Barrier-type terminal blocks provided on all power supplies. Each terminal block features a barrier on three sides of each terminal to help prevent accidental shorting of field wiring. Power supply terminal blocks have finger-safe covers. This style of terminal block meets U.S. and European market needs. Front access replaceable fuse with cover protects the power supply from most short circuit conditions. Clear fuse cover allows the operator to visually inspect the fuse while it protects the operator from potential shock hazards.

3 1769 Compact I/O Power Supplies and Communication Bus Expansion Cables 3 Once the power supply and modules are locked together, the system becomes a rugged assembly. The entire assembly can be handled as a unit until it is panel or DIN rail mounted. ~ Upper and lower tongue-and-groove slots guide the power supply during installation and secure the power supply and I/O modules within the system. Expansion power supplies and I/O modules can be installed or replaced from the front without dismantling the system. Self-lifting field-wire pressure plates cut installation time. Wiring terminals have self-lifting pressure plates to secure two #14 AWG field wires. The patented bus connector with locking function ensures reliable system communication. The lever of the bus connector has a mechanical detent that latches and locks the lever in place. This system provides superior performance in vibration sensitive applications. The 1769-CLLx, -CRRx, and -CRLx cables are available in two lengths to extend the 1769 bus communication lines. A maximum of two cables can be used in a 1769 system, allowing for three banks of I/O modules. The MicroLogix 1500 uses a maximum of one cable and one power supply. The 1769-ADN DeviceNet adapter allows expansion to three banks. All power supplies and cables carry certification by UL and C-UL. Certification includes Class I, Division 2 Hazardous Location, Groups A, B, C, D. All modules are also CE compliant for all applicable directives.

4 Compact I/O Power Supplies and Communication Bus Expansion Cables Power Supply Requirements Using an expansion I/O power supply increases the system s capacity for adding additional I/O modules to your system, such as the 1769-IF4 and 1769-OF2 analog modules. An additional I/O bank (see illustration below) is connected to the system via a 1769 communication bus expansion cable. The additional I/O bank must include a power supply. An end cap/terminator (1769-ECR or 1769-ECL) must also be used if the I/O bank is the last in the system. The maximum number of Compact I/O modules any single 1769 power supply can drive is 16. (The drive current must also be within the power supply limits.)

5 1769 Compact I/O Power Supplies and Communication Bus Expansion Cables 5 MicroLogix 1500 System Expansion If the power capacity of the embedded MicroLogix 1500 power supply is insufficient to drive all the I/O modules in the system, a 1769 power supply can be used. A maximum of one 1769 power supply and one communication cable can be used in a MicroLogix 1500 system, allowing for two banks of I/O modules (one connected directly to the controller, and the other connected via the cable). Each I/O bank requires its own power supply (Bank 0 uses the controller s embedded power supply). In either case, the expansion I/O limit of eight modules cannot be exceeded.

9 1769 Compact I/O Power Supplies and Communication Bus Expansion Cables 9 Considerations for System Expansion using Power Supplies and Cables The following worksheet is provided to assist in system expansion validation using 1769-PA2 and -PB2 Power Supplies with Communication Bus Expansion Cables. Expansion power supplies must be used with the expansion cables. Only one power supply may be used on an I/O bank. Using an expansion power supply on the same I/O bank as your MicroLogix 1500 controller or two expansion power supplies on the same bank may damage a power supply and may result in unexpected I/O operation. Use the worksheet below to account for the amount of 5V dc and 24V dc current consumed by your expansion I/O and user supplied equipment.
