The single-function time relay PCM-03 is used to perform the function of cyclic switching in automation and control systems. The relay is triggered by the supply voltage. It is characterized by a very wide range of time settings from 0.1 second to 10 days. Additional ON / OFF functions enable permanent switching on or off of the receiver. The system has indicators of: supply voltage, relay status and time measurement - realized by means of LEDs. Time setting range t: discrete 0.1 ÷ 1 s; discrete 1 ÷ 10 s; discreetly 0.2 ÷ 1.7 min; discreetly 1 ÷ 10 min; discreetly 0.2 ÷ 1.7 h; discreetly 1 ÷ 10 h; discreetly 0.4 ÷ 4.2 days; discreetly 1 ÷ 10 days.
