Product Description
The Sprecher + Schuh CS7-31E industrial control relay is rated for 10 AMPS continuous duty (25 AMP general purpose), has 3 normally open (N.O.) and 1 normally closed (N.C.) power poles and comes with an AC rated coil (must specify coil voltage above). This 4 pole relay has screw terminals and can be mounted on standard 35MM Din rail or screw-fixed to the back of a panel. Up to 4 additional auxiliaries can be added to the CS7-31E via two pole side mounted or four pole top mounted auxiliaries, for a maximum of 8 contacts per unit.

The Sprecher and Schuh 4 pole relays are unique for both their reliability and compact size. Each relay comes with a standard 4 poles and additional auxiliary contacts can be added for up to 12 total poles (4 top mounted and 2 side mounted for each side). These relays use the same auxiliary contact blocks as the CA7 contactors and are easily installed without tools. CS7 control relays are perfect for fail-safe control circuits. An interlock contact design, which maintains minimum 0.3mm clearance, prevents the NC contact from reclosing if the NO contact is welded when in operation. This feature not only includes the base contact poles, but extends to the front and/or side mounted auxiliary contacts. This is a requirement in safety circuits and is backed by SUVA-PRO certification.
