The Amperite 26F90 NSMP is an electromechanical time delay relay designed to introduce a controlled delay in electrical control circuits. As a timed switch, it energizes or de-energizes a circuit after a defined interval, enabling sequencing and interlock operations in automation systems. The 26F90 NSMP designation identifies the specific relay model within Amperite's lineup of electromechanical time delay relays.
