Buyer's Guide

When selecting the DILM9-01 for your application, verify the coil voltage (24V DC, 120V DC, 230V AC, etc.) and terminal type (screw vs. push-in). The standard DILM9-01 includes one built-in NC auxiliary contact, making it ready for control circuits that require a break contact. For applications requiring additional auxiliaries, add-on contact blocks are available.
