51201602-100 | Honeywell | Pulse Input Module

The Honeywell 51201602-100 is an 8-channel pulse input module designed to capture and process high-precision pulse signals from field equipment such as flow meters, counters, and encoders. It provides real-time signal processing and integrates into Honeywell TDC 3000 and Experion PKS control platforms.

Input Signal Processing and Channels

The module features 8 independently configurable input channels. With 16-bit resolution, it converts incoming frequency or pulse trains into digital data for process calculations. Each channel executes signal acquisition at a sampling rate of 10 samples/sec.

Status Diagnostics and System Integration

Front-panel diagnostic LEDs provide local status indication for module power, individual channel signal activity, and operational errors. Operating on a nominal 24 VDC supply with a typical power consumption of 5 W, the unit interfaces directly with system controller backplanes.

Physical Design and Environmental Tolerances

The module is housed in an IP20-rated enclosure designed for standard DIN rail installation. It operates across a temperature range of -20 deg C to +60 deg C and can be stored in ambient conditions ranging from -40 deg C to +85 deg C.
