Sequential Timer with power supply (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12176
Indian Lab Suppliers supplies the Sequential Timer with power supply (C.R.) (Product ID: 12176) as part of its electronics engineering lab equipment range. It is a self-contained board showing how three cascaded timer ICs run a timed sequence of relay outputs.
Quick Answer
Three timer ICs are connected in cascade, each with its own adjustable period of roughly 2 to 15 seconds and an LED showing when it is active. A push-to-on switch triggers the sequence, a push-to-off switch resets all timers, and a toggle switch sets automatic continuous sequencing. Relay contacts on the panel allow external loads to be switched, as in automatic control, testing or machine sequencing. The circuit runs from a 12 V, 200 mA IC-regulated supply. The relay contact rating is not stated; please confirm it at quotation before connecting a load.
