The control panels of modern machines and plants must be able to convey increasingly complex information, even though the available space is limited. The RMQ 16 range of compact control circuit devices provides the solution. The various front elements can be mounted flush on all four sides, without any gaps. These control circuit devices can be fitted with LEDs instead of filament bulbs. This means no more changing of bulbs, because LED service life equals machine life. The high degree of protection, IP 65, of the front elements ensures safe operation even in harsh environments. This makes RMQ 16 ideally suitable for industrial applications.
