Module Overview

The 1746sc-CTR4 and the 1746sc-CTR8 are 4 and 8 channel Counter/ Flow
Meter modules. The modules are suitable for general purpose counter and flow
meter applications that require a large number of input channels and high
accuracy. The module supports both AC and DC input signal types. The counter
functions include programmable control of the counter including start, stop,
reset, preset control and user defined flags. The input levels for the counter
mode are 5, 12, and 24 volts DC. The Flow Meter mode is compatible with
variable reluctance AC input. This differential AC input will count AC zero
crossing signals from 50 mV to 75 V peak.
