Connectors and Interfaces


Top


DC Bus Input

Input connector for DC bus power. Nominal 72V, but can operate anywhere in between limits defined in JCS Standard Voltages.

Connector

Connector type Solder pads / AMASS XT30F

Pins Description

Pin Signal Description
1 GNDV DC bus power return
2 +VDC DC bus power input

WARNING:

No reverse polarity protection is implemented on the DC bus input connectors.

NOTE:

Device has an 85V TVS diode across the DC bus input.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


External Resistor Interface

Connector

Connector type Solder pads / Amass XT30M

Pins Description

Pin Signal Description
1 RES0 Resistor connection - switch side
2 RES1 Resistor connection - +VDC side

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


12V Supply Interface

Connector

Connector type Molex PicoClasp 4 Pins
Mating part number 5019390400

Pins Description

picoclasp 4 pin pinout

Pin Signal Description
1 +12V +11V minimum, +13V maximum
2 +12V
3 GND
4 GND

NOTE:

This connection is required. The device does not generate internal 12V from the DC Bus input.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


JCS Network Interface

One network input connector and one network output connector. Interface is galvanically isolated. Power to the isolated side of the network is derived from the host device, eg a joint controller.

NOTE:

If this device is the last in a network chain the output must have the loop back connector installed.

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.

Connector

Connector type Molex PicoClasp 6 Pins
Mating part number 5013300600

Wiring Diagram

picoclasp 6 pin JCS net pinout

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.


Analog Channel Interface

Specification

Input Single ended, ESD protected
Input voltage range 0V - 3.3V

Pins Description

picoclasp 3 pin pinout

Pin Signal Description
1 +3V3 3.3V out
2 GND Analog return
3 AN_IN Analog signal in

WARNING:

This connection is NOT hot pluggable. Ensure the system is powered down before removing or plugging in.
