Product Description

X-CI 24 51 is a NonSIL counter module intended for use in the programmable electronic system

(PES) HIMax.

The module can be inserted into any of the base plate slots with the exception of the slots

reserved for system bus modules. For more information, see System Manual (HI 801 001 E).

The module is used to count the pulses, to measure the frequency and the rotational speed

and, if defined, to recognize the rotation direction. Two channels are required to use the

recognition of rotation direction function, see Chapter 4.5.4.

Proximity switches in accordance with EN 60947-5-6 (NAMUR) or control circuit devices of

type 3 in accordance with EN 61131-2 can be connected to the counter module. Proximity

switches and control circuit devices may not be operated simultaneously.

It can be operated with safety-related modules and other NonSIL modules within one base

plate. Safety-related and NonSIL modules may not be wired redundantly.

The module is interference-free, in particular, with respect to EMC, electrical safety,

communication to the X-SB and X-CPU modules, as well as the user program.

Module and connector boards are mechanically coded, see Chapter 3.6.1. Coding avoids

installation of improper I/O modules.

Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards used to

test and certify the modules and the HIMax system.
