Figure 1 shows a simple circuit using the MC9S08QE128 microcontroller from Freescale to drive a Finder 40.61.6.005 single-coil latching relay with a standard ULN2003 Darlington driver with open-drain ...

A new latching relay output module provides fail-safe control by latching the last output contact state, on or off, prior to power-down. The G-1AMPx-LTCH relay module is compatible ...
