SML-110 Switch Machine Locks

The SML-110 Switch Machine Lock is a vital conditional power supply that provides power to a switch machine. It delivers a nominal 120 Vdc output with a limited current of 23 amps from an ac or dc source when activated by a nominal 12 Vdc input. This output is sufficient to simultaneously drive two switch machines. To deliver an output voltage, the SML-110 requires the presence of two out of three inputs: Switch machine lock and either the normal or the reverse position request. These inputs can be relay contact closures or outputs from an interlocking processor such as the MicroLok® II system or MicroLok Object Controller. The output voltage of the SML -110 is fed.
