pulse input module

The YOKOGAWA APM11 is a pulse input module for the CENTUM CS and CENTUM VP distributed control systems. It converts contact closures, voltage pulses, and current pulses into signals usable by the control system, and is commonly used for flow measurement and high-speed counting applications.

The YOKOGAWA AAP149 is a 16-channel pulse input module for the CENTUM VP / CS 3000 distributed control system, specifically designed to be compatible with the PM1 processor module. It receives pulse train signals from field devices (such as flow meters, tachometers, and encoders) via pulse input signal conditioner cards and counts them for process monitoring and totalization.

The YOKOGAWA AAP135 is an 8-channel isolated pulse input module for the CENTUM VP / CS 3000 distributed control system. It is designed to receive contact ON/OFF, voltage pulse, and current pulse signals from field devices such as flow meters, tachometers, and power transducers.

The Triconex 3511 is an 8-channel TMR Pulse Input Module for the Tricon Safety Instrumented System (SIS). The module employs Triple Modular Redundant (TMR) architecture with 2-out-of-3 (2oo3) hardware voting, ensuring that a single channel fault cannot cause a spurious trip or prevent a valid emergency shutdown.

The Honeywell 51304084-275 is the CE compliant, conformally coated variant of the MC-TPIX52 Pulse Input Field Termination Assembly (FTA) for the Honeywell TDC 3000 / HPM distributed control system (DCS). It provides screw-terminal termination for 8 pulse input channels, accepting rectangular or sine wave signals, and is used in conjunction with the Pulse Input IOP (MU-PPIX02 or MC-PPIX02).
