Relay 7

In many industrial applications, 12V or 24V control signals are required. However, most embedded controllers support only TTL level (0-5V) input or output. The Relay7 (R7) is designed to support TTL-level and high-voltage (up to 30V) signal conversion. Seven power relays are provided on the R7. Each power relay provides Normal Close, Normal Open, and COM contacts, and are rated for 10 A operation.

Seven relay status indicator LEDs and an additional seven solenoid drivers are also on-board. These seven high-voltage I/O channels are hardware configurable as 0V to 30V inputs or as 0V to 30V outputs at the screw terminals.


The VE232 measures 2.3 by 1.4 inches. It takes unregulated +9-12V DC input, and provides regulated +5V power, negative voltage, two RS-232 drivers, and one RS-485 driver. It connects to the controllers via a 10x2 header. The VE232 is useful in providing drivers and voltage sources for the various engine controllers.
