Lowell MSM
Momentary Switch Module

MSM

Lowell's MSM momentary switch module allows equipment connected to Lowell’s remote power control Series RPC or four-step sequencer Model SCS-4 to be switched from multiple locations.  The MSM is used between the RPC control and multiple momentary style switches or between the SCS-4 sequencer and multiple momentary style switches.

The MSM converts normally open momentary contact closures to latching maintained closures.  This function allows for multiple switches in a variety of locations to activate the equipment connected to the RPC Series power controls or the SCS-4 sequence controller.  When the MSM is connected, a momentary closure (on/off) on any remote switch causes the MSM to change state - from open to closed or from closed to open.  This change causes the RPC or SCS-4 to turn "on" or "off".

Dual terminal strips are provided for connection of two SPST momentary-style switches.  Additional switches may be added in parallel; 4 total for use with RPC Series and 12 total for use with SCS-4 Series.  An LED indicator displays the "on" or "off" status of the system.  The MSM requires no external power source as it draws its power from the 'host' unit (RPC Series or SCS-4).

The compact steel chassis includes mounting holes, a connection diagram and black powder epoxy finish.  Its compact size is ideal for mounting in a closet, above the ceiling, to a blank rack panel or rack shelf Model L15-315E with a closure/security panel and pre-punched holes for mounting small chassis-style devices.
