Honeywell 51201602-100 Pulse Input Module

Overview

The Honeywell 51201602-100 is an 8-channel pulse input module for industrial automation. It acquires high-speed pulse and frequency signals from devices such as turbine flowmeters, encoders, and speed sensors. The module supports dry contact, open collector, TTL/CMOS, and 24V active inputs. Its advanced signal processing reduces noise and false triggers. Users can perform pulse counting, frequency measurement, and Sequence of Events (SOE) recording. The plug-in design integrates seamlessly with Honeywell TDC 3000, TPS, and HC900 systems. This module suits flow measurement, rotational speed monitoring, and event logging applications.
