PLRCr Module

(Pulse Latching Relay Controller)

 The PLRCr is an electric switch (no mechanical contacts to wear out) that will activate and deactivate its output based on a short input trigger pulse, or series of pulses. 

 

The PLRCr is great for push button applications and for using any standard relay as a latching relay.

 

For ease of installation, the trigger pulse can be ether a 12v pulse or a grounding pulse.  The triggering pulse time must AT LEAST 0.1 seconds long.  Longer or shorter pulse times are available upon request.  A dead time of 0.1 seconds is provided between triggering pulses to prevent false triggering, during this dead time additional pulses will be ignored until 0.1 seconds after last detected pulse.  Longer or shorter dead times are available upon request. The PLRC module’s output (when “On”) can ground 2.0A directly or the output can be used to activate a relay to supply loads of any power requirements. 

 

The standard PLRCr turns “On” (or “Off”) it’s output after receiving one pulse, it will keep its output in this state (“On” or “Off”) until it receives another pulse. 

 

Multi-Pulse versions of the PLRCr are also available.  The PLRCr module can be (programmed by us) to require two or more pulses within a certain amount of time (a time window) in order to change the module’s output status.  To order the multi-pulse version, please specify the number of pulses required (2 or more) and the time window (in seconds) that the PLRCr must receive these multiple pulses in. 

The PLRCr will normally default to the output Off state when powered up (Default to Off), but other options are Default to On, and Default to last state.  When defaulting to last state, the PLRCr will remember whether its output was On or Off when it last powered down, it will turn back to On, or Off, the next time it is powered up.  You can request Default On or Default to last at the time of purchase.

The PLRCr module is Factory Re-Programmable; If you ever need new settings programmed into your module, just email us for a reprogramming quote and Return instructions.

Dual-PLRC Module

Dual-(Pulse Latching Relay Controller)

  

The Dual-PLRC is an electric switch (no mechanical contacts to wear out) that will activate, and deactivate, its two outputs based on a short input trigger pulse, or series of pulses, to its two trigger wires.  It essentially has the function of two of our standard PLRC modules.  Perfect for applications where space and weight is limited.

 

The Dual-PLRC is great for push button applications and for turning any inexpensive relay into a latching relay.

 

For ease of installation, positive (12V) triggering or negative triggering (grounding) is available upon request.  Let us know at the time of purchase which option you want for each of the two inputs.  The triggering pulse time must AT LEAST 0.1 seconds long.  Longer or shorter pulse times are available upon request.  A dead time of 0.1 seconds is provided between triggering pulses to prevent false triggering, during this dead time additional pulses will be ignored until 0.1 seconds after last detected pulse.  Longer or shorter dead times are available upon request.

 

The Dual-PLRC module’s two outputs can be ether a grounding type (AKA low side switch), or it can supply 12v (AKA High side switch).  The gournding type of output can "sink" up to 2.0 Amps continuous, with up to a 3 Amps turn-on surge current.  The positive type of output can supply up to 1A continuous with a 3A turn-on surge

 

There are 16 possible configurations of the Dual-PLRC:

 Possible choices for input and output #1

(Positive trigger In, Negative Output)

(Positive trigger In, Positive Output)

(Negative trigger In, Negative Output)

(Negative trigger In, Positive Output)

 And the same choices,as above, for input and output #2.

 

 

The standard Dual-PLRC turns “On” (or “Off”) it’s output after receiving one pulse, it will keep its output in this state (“On” or “Off”) until it receives another pulse. 

 

Multi-Pulse Dual-PLRC versions of the PLRC are also available.  The Dual-PLRC module can be (programmed by us) to require two or more pulses within a certain amount of time (a time window) in order to change the module’s output status.  To order the multi-pulse version, please specify the number of pulses required (2 or more) and the time window (in seconds) that the Dual-PLRC must receive these multiple pulses in.
