Two external power supplies are required to operate the RB-TK2051: VCC (referenced to GND), and V5

(referenced to G5). The V5 ground (G5) must be kept separate from the VCC ground (GND). GND and G5

are joined at a common point on the EB-TK2051 with a 0Ω resistor (R1).

The Minimum and Maximum VCC supply voltages are +10V and +30V, respectively.

The V5 supply voltage is 5V. Please see the TK2051 Data Sheet for Minimum and Maximum values.

The VCC and V5 power supply connection is a standard 4-pin .156” Molex header (JP4). Please refer to

the Board Connection Diagram for the connector locations on the EB-TK2051.

OUTPUT

The output connections for each channel of the RB-TK2051 are made with standard 4-pin .156” Molex

headers (JP1, JP3, JP4). The output of the TK2051 is differential; therefore each output has a positive

output (OUT_+) and a NEGATIVE OUTPUT (OUT_-).

Please refer to the Board Connection Diagram for the connector locations on the RB-TK2051.

INPUT

The input connections of the RB-TK2051 are made with a standard 7-pin .100” Molex header (J1). There

are six inputs and one common Agnd. Please refer to the Board Connection Diagram for the connector

locations on the RB-TK2051.
