Three Impulse Relay For Engine Starting Circuits

Pro-Tech Engg offers the Protime brand 3 impulse relay, a readymade solution for engine starting circuits like diesel generator and fire fighting pumps. It has two relay outputs. The RL1 is to give starting impulses (On and Off time adjustable) and the RL2 is to give `Fails to start' alarm/ indication after factory set number of attempts are completed, which is generally set to 3 attempts, but can be made as per requirement. The relay gives an indication for RL1 On Time/Off Time, Power Supply and RL2 On. Total wireless design makes it more rugged and errorproof along with smart mechanical design to fit the relay on any standard mounting channel. It is readily available in 12 V and 24 V DC models with power supply variation capacity of 25%. Range of time is 2-15 secs. The screwless version of relay is also available. The size of the relay is 70 mm (W) x 110 mm (H) x 110 mm (D).
