The 1C31147G01 is a Pulse Accumulator Electronics Module engineered for the Emerson Ovation DCS. It accumulates pulses from two independent input channels, enabling frequency measurement, totalized counting, or pulse duration timing. When paired with a compatible Personality Module (1C31150G01, G02, or G03), the 1C31147G01 accepts 5V, 12V, or 24/48V input signals and provides a 15-bit counter output with configurable input filtering, debounce, and count direction. The module supports internal timebase selection (100 kHz, 10 kHz, or 1 kHz) and offers 1000V isolation for reliable operation in industrial environments.
Mounting: Installed in a standard Ovation I/O Base Unit mounted on a DIN rail.
Module Pairing: Requires a Personality Module (1C31150G0x) selected based on input signal type and power configuration.
Field Wiring: All field inputs must use shielded cable. Terminal block connections vary by Personality Module (common negative, common positive, or dedicated external power).
Personality Module Options:
1C31150G01: Common negative (low-true inputs).
1C31150G02: Common positive (high-true inputs).
1C31150G03: Dedicated external DC power supply for field inputs
Dual-Channel Counting: Two independent input channels for versatile pulse accumulation.
Multiple Input Voltage Support: Accepts 5V, 12V, or 24/48V field inputs.
Configurable Functions: Supports count pulses, measure pulse width, measure period, or measure speed.
Programmable Input Filtering: Adjustable filter and debounce settings for noise immunity.
Flexible Counter Control: Configurable count edge (leading/trailing), reset on snapshot or read, and external enable/snapshot inputs.
High Isolation: 1000V AC/DC isolation between channels and logic.
Hot-Swap Capable: Supports online replacement for streamlined maintenance.
The 1C31147G01 functions as a high-speed pulse accumulator for the Ovation DCS. It accepts pulse inputs from field devices such as flow meters, encoders, or tachometers. The module's microcontroller processes these signals based on configuration settings—counting pulses, measuring frequency, or timing pulse duration. An internal timebase (100 kHz, 10 kHz, or 1 kHz) can be selected as an alternative count source. The 15-bit counter value (bits 14-0) is updated with Bit 15 serving as a new data available flag. External control inputs (Enable and Snapshot) provide additional counting control. The module communicates with the Ovation Controller via the serial I/O bus, requiring the RPACNT or RPAWIDTH algorithm to reside in the Controller for proper operation.
Q1: What is the primary function of the 1C31147G01?
A: The 1C31147G01 is a Pulse Accumulator Electronics Module that counts pulses from two input channels, enabling frequency measurement, totalized counting, or pulse duration timing in the Ovation DCS.
Q2: Which Personality Modules are compatible with the 1C31147G01?
A: It is compatible with the 1C31150G01 (common negative), 1C31150G02 (common positive), and 1C31150G03 (dedicated external power) Personality Modules.
Q3: What input voltage levels does the 1C31147G01 support?
A: It supports +5V (high speed), +5/12V (medium speed), and +24/48V input signals.
Q4: What is the counter output resolution of the 1C31147G01?
A: The module provides a 15-bit counter output (bits 14-0), with Bit 15 serving as an update bit indicating new data availability.
Q5: What Ovation algorithms are required to use the 1C31147G01?
A: The RPACNT or RPAWIDTH algorithm must reside in the Ovation Controller.
