Spectrum Controls 1746sc-CTR4 - Manual (Page 20)

20 SLC 500 ™ 50 KHz Counter / Flowmeter Input Module
Module Addressing The CTR-8 module uses 32 input and 32 output registers, and the CTR-4
module uses 16 input and 16 output registers. Both modules use Class
III mode operation and cannot be used with Class I operation. The
following memory map shows you how the SLC processor’s output and
input tables are defined for the module. The SLC 5/01 processor does
not support Class III operation and is not compatible with this module.
This module is not suitable for use in remote rack applications with ASB
modules due to the input / output word size.
