Syvecs X4 Expander

£450.00 (+VAT)

The Syvecs X4 Expander is a compact but very powerful expansion unit designed to offer an additional 4 Inputs and outputs allowing customers to maximises other strategies on the range of Syvecs Engine Control Units. By adding an expansion unit, it allows more sensors and parameters to be logged via Datalogging . CAN Interfaces provide communication to ECU’s or Displays.

Included with the Expander is a comprehensive connector kit which includes the plug & pins ready for installation. We also include the Syvecs X4 Expander Mount free of charge with all new purchases.

The X4 Expander is fitted with four Half Bridges drivers which are capable of driving Low, High or joined in pairs as a full bridge motor driver. Each of the four H-Bridge Outputs is equipped with a current monitoring circuit which can be assigned in strategies on Syvecs Engine Controllers or as Current Limiting functions in other applications.

Four MagnetoResitive circuits make reading the ABS sensors found on most new automotive applications easier by just needing to connect one side of the sensor to the X4 and the other side to Ground.

The four 0-5v Analog inputs are not capable of frequency detection but are useful for monitoring of switches, pressure transducer or positional sensors.

Able to withstand the toughest of conditions and high temperatures the X4 is useful for many applications whether it’s for external Drive By Wire support, Electronic Wastegates, Fuel Pump Controller and more.

Two canbus interfaces are fitted on the X4 which are setup out of the box for Slave Control with a any of the Syvecs S7,S8,S12 Ecu or can Support for other Ecu’s.
