Description

The 2502 is a two-channel High Speed Counter Input

Module designed to count incoming pulses from

external sensors and provide process control outputs

based on count status.  It is compatible with the CTI

2500 Series®  and Simatic®  505 PLC systems and a

direct replacement for the Siemens® 505-7002 . The

2502 provides two independent counter channels.
