TK-415

Clock sequential-combinational ТK-415 is a microprocessor-based programmable device for switching at a pre-set by the user periods 15 receivers one after the other (sequential mode) or in certain combinations (Combination mode).

Basic functions:

• microprocessor controlled.
• simple change-over between sequential and combination timer.
• 7-segment LED indications.
• cascade connection of several devices for extended total number of channels.
• memorization of device mode after switching off and program operation restart from breakage.
• inputs for timer start and pause control.
• fast resetting.
• copy of settings.
• program can be executed only one time or/and cyclic operation possible.
