Description

The 2588-8 8-Point Universal Discrete Input Module

accepts a wide range of voltage signals. It is de-

signed to accept both AC and DC voltage allowing

the user to pick and choose ranges on a single

module. The 2588-8 can replace Siemens® 8 point

input products with no rewiring. Motor centers,

optical sensors, limit switches and utility control are

excellent examples of applications for this product.
