Level control relay RM22-L - 380..415 V AC - 1 C/O
Description
This Harmony RM22-LG relay allows monitoring of liquid level control in 3-phase networks." This modular multi function 3-phase liquid level control relay is ideal for monitoring of electrical values in industrial and building control panels." "It applies to a wide type of industrial automation applications such as hoisting, packaging, lifts, textile, water." "It has one of market slim form-factors with 22.5mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device." "It also offers a diagnostic button, sealable cover, simple and precise settings with screw trimmers." "It provides automatic shutdown management and fault information to user for a quick fault identification and troubleshooting." "multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC." 0 0 0 0 0 0 0 0 0
