特点:
台达Tau UBUS背板附件提供一个背板,用于连接多个3U格式电路板和一个ACC-E1电源。背板通过每块板上的96针DIN连接器将UMAC CPU板连接到其伺服和I/O接口板,并通过一条称为UBUS的共享总线。Delta Tau的背板有几个潜在的重要特性。首先,他们有一个特殊的连接器用于ACC-E1电源,因此不需要特殊的电源接线。其次,每个电源电压(+5V、GND、+15V、-15V和AGND)在背板上都有一个宽平面连接。第三,所有三排都在连接器之间通过总线连接。最后,信号走线以一种为在UMAC中使用而优化的方式端接。

POWER UNIT
Features:
- 4 to 18 Slots
- +1 Slot for Power Supply Connection
The Delta Tau UBUS backplane accessories provide a backplane board for connecting multiple 3U-format circuit boards plus an ACC-E1 power supply. The backplane boards connect the UMAC CPU board to its servo and I/O interface boards via the 96-pin DIN connectors on each board across a shared bus called the UBUS. Delta Tau’s backplane boards have several potentially important features. First, they have a special connector for the ACC-E1 power supply, therefore special wiring of power sources is not required. Second, each supply voltage (+5V, GND, +15V, -15V, and AGND) has a wide plane connection across the backplane board. Third, all three rows are bussed between connectors. Finally, the signal traces are terminated in a manner optimized for use in the UMAC.
