1) Coil supply voltage: All E290 50Hz devices can be supplied with AC or DC control voltage.
The ratio of 1 : 0.5 applies, i.e. a 230 VAC coil can also be used for 110 VDC. (See Ordering data.)
NO = normally-open contact; NC = normally-closed contact; CO = changeover contact
* for 50 Hz devices only
