Brentek Latching Output Modules provide "fail-SAFE" control where the last contact state must be maintained when power is removed or lost. These modules latch the last output contact state (ON or OFF) prior to power-down (LATCH Mode).  When the power is applied, the output "follows" the input (TRANSPARENT Mode).  An inverse logic mode is available as an option.

Power to the module is only required to change the output contact state (<3mS), making control applications practical where power is limited, such as in solar powered or battery powered equipment.  The LED indicator operates from an auxiliary set of internal relay contacts to indicate the true state of the output contact in “real-time” (when power is applied). The output contact state is latched by low voltage sense circuitry. Optional power-on delay circuitry prevents any state change during system start-up.

The G-1AMPx-LTCH module is compatible with industry standard I/O mounting racks for G-Series, G4, G5 and C4 type (5 pin) modules and are available for 5V, 12V, 15V and 24V logic operation with the following base model numbers:

  • G-1AMP5-LTCH
  • G-1AMP12-LTCH
  • G-1AMP15-LTCH
  • G-1AMP24-LTCH
