Connectors and Interfaces
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
| 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.
