Introduction

Electronic Time Relay ETR10 is a solid state On delay timer that operates with high repeat accuracy between wide limits of voltage, frequency and temperature. Use of glass-epoxy PCB eliminates chances of leakage or breakdown.The power supply is indicated by a Green LED marked 'V' (Voltage), while the time out is indicated by a Red LED marked 'D' (Delay).The time setting   is continuously adjustable and can be set on a fairly linear scale giving ten divisions of the particular range, on the dial.The timer  comes in a molded plastic casing.The terminals are designed in slots so that the live parts are not easily touchable. The timer  is available both for flush mounting (ETR10F) and for projection/base mounting (ETR10P).

Application

The time relay has a wide field of applications starting from star-delta starter, machine tools controls, plastic and rubber machine controls, chemical process controls, material handling sequence controls, down to every sort of control requiring timed sequence
including advertising signs, photographic exposures, etc.
