ETX-1640x Terminal Block Connections

Certain connections within the High-Power Production Test Base System are routed through a bank of DIN rail-mounted terminal blocks that are located in the side space of the rack.

TB1 through TB11 can be used to provide 24 V DC power to devices configured in the system. Refer to the following schematic for information about existing fuses.

The RM-26999 (power measurements conditioner) receives power from the DIN rail-mounted terminal blocks.

Several connections relevant to the system interlock circuits also run through the DIN terminal blocks. The Test System Maintenance Software may indicate if connection or component discovery issues are related to this bank of terminal blocks.

TB19 through TB24 in the following schematic break out several pins directly from slot J1 on the mass interconnect. These terminal blocks are available for user configuration. The connected pins in slot J1 are suitable signals of up to 60 V DC and 240 mA.

The following figure is a full schematic of the DIN rail-mounted terminal blocks. Refer to the schematic when performing maintenance or repairs.
