The Victron Energy BPP900800150 GX IO-Extender 150 expands the input and output capabilities of a compatible Victron GX device, providing additional interfaces for sensors, controls, automation, and external equipment. It connects to the GX device through USB, which also supplies operating power, creating a streamlined expansion solution for more advanced system control.

The GX IO-Extender 150 provides configurable digital I/O, PWM outputs, potential-free latching relays, and a solid-state switching output. It can be controlled through Node-RED on the GX device and through the Switch pane in the GX user interface, supporting customized automation and control logic. 

Key Technology

• Expanded GX Input & Output Capability
  Adds additional I/O functionality to a compatible GX device for integrating sensors, controls, and other external equipment into the Victron system.

• Configurable Digital I/O
  Provides eight digital I/O channels that can be configured as eight inputs, eight outputs, or four inputs plus four outputs, giving installers flexibility for different monitoring and control requirements.

• PWM Control Outputs
  Four PWM channels provide precise output control for compatible applications, with LED indication for channel state.

• Potential-Free Latching Relays
  Two bi-stable latching relays provide potential-free switching for compatible external circuits while minimizing continuous power requirements.

• Solid-State Switching Output
  A dedicated solid-state output can control compatible resistive, capacitive, and inductive DC loads within the specified electrical limits.

• USB Powered
  Connects to a compatible GX device through USB and receives its operating power through the same connection, simplifying system integration.

• Node-RED Integration
  Supports configuration and control through Node-RED on the GX device, enabling customized automation rules and system logic.

• Flexible Mounting
  Designed for wall mounting and can also be installed on DIN rail using an appropriate adapter accessory.

Best Uses

• Victron GX System Expansion
  Ideal when a compatible GX device requires additional digital inputs, outputs, relays, PWM control, or solid-state switching capability.

• Sensor & Control Integration
  Useful for connecting compatible sensors, switches, status signals, and external control equipment to a GX-based system.

• Node-RED Automation
  Suitable for systems using Node-RED to create customized control sequences, automation rules, and logic based on system conditions.

• External Equipment Control
  The integrated switching outputs can interface with appropriately specified external loads and control circuits within their electrical ratings.

• Advanced Energy System Monitoring
  Provides additional interfaces for GX-based installations that require more monitoring points and automated control functions than the GX device alone provides.
