SIMATIC S7-200 EM 221 8DI 24V DC Digital Input Module

Condition
New Original

Warranty
One year

PRODUCT SNAPSHOT

The EM 221 expands compatible S7-22X CPUs with eight optically coupled 24 V DC digital inputs. The channels are isolated in groups of four for dependable field-signal acquisition.

Support for two-wire sensors and long shielded cable runs makes it suitable for compact machines and installed S7-200 systems requiring additional discrete inputs.
