CM-IWS - Insulation monitoring relays. CM-IWS series relays are used to monitor insulation resistance and can be configured to meet application requirements. All devices offer two different connection versions: screw connection technology and Easy Connect technology. Rated control supply voltage: 24-240 V ac/dc. The device can monitor control circuits (single-phase) and main circuits (3-phase) with a measuring range of 1-100 kΩ. Precise threshold setting in steps of 1 kΩ. Detection of broken wires. Three LED indicators for operating states. One changeover contact (1-pole changeover switch), closed circuit principle.
