GEMO Control Relays

GEMO Control Relays prices and range: 14 models with current prices, stock status and specifications at Welibaba. Control relays are panel devices that monitor a quantity such as time, light, liquid level, current, voltage or temperature and change the position of the output contact when a set condition occurs; they are chosen according to the quantity to be monitored, the supply voltage, the number and current of the output contacts, and the mounting style. They are used in motor and pump panels, lighting automation and machine control circuits to switch a load on and off depending on time, daylight, tank level or mains conditions. The subgroups include timer relays, safety relays, photocell and astronomical timer relays, liquid level relays and their accessories, submersible pump control relays and staircase timers. Directly in this category, ABB CM series current, voltage, phase, temperature and insulation monitoring relays and motor protection relays with thermistors are listed. Most of the products are ABB, Tense, Siemens and Schneider Electric brands. A general-purpose monitoring relay is not considered sufficient for a machine safety function; for this job, see the safety relays subgroup.
