Digital input modules are available in densities of 8, 16, and 32 points. A full range of voltages from 12VDC to 240VAC and output currents up to 2A per channel are supported.

The 2580 16-point discrete input module accepts sixteen discrete isolated inputs to the CTI 2500 Series® or Simatic® 505 I/O base.

The 2581 16-point discrete input module accepts sixteen discrete isolated inputs to the CTI 2500 Series® or Simatic® 505 I/O base.

The 2582 16-point discrete input module accepts sixteen 125 VDC discrete isolated inputs to the CTI 2500 Series® or Simatic® 505 I/O base.

The 2585 16-point isolated TTL input module accepts sixteen TTL inputs to the CTI 2500 Series® or Simatic® 505 I/O base.

IMPORTANT NOTE:  THE 2588-8 HAS BEEN MATURED.  IT IS DIRECTLY REPLACED BY THE 2589-B 8/16/32-POINT UNIVERSAL INPUT MODULE The 2588-8 is designed to accept both AC and DC voltage inputs and is compatible with the CTI 2500 Series® or Simatic® 505 I/O base.

The 2589-A is designed to accept both AC and DC voltage inputs and is compatible with the CTI 2500 Series® or Simatic® 505 I/O base. The 2589-A can be configured to login as 8, 16 or 32-points. In 240VAC applications, up to 16 points can be used.

The 2589-B is designed to accept both AC and DC voltage inputs and is compatible with the CTI 2500 Series® or Simatic® 505 I/O base. The 2589-B can be configured to login as 8, 16 or 32-points. The 2589-B allows operation of all 32pt at 240VAC, compared to only 16pt which were available on 2589-A.
