Durant Ambassador 57600 Series Counting Controller

Durant Ambassador 57600 Series Counting Controller: A Multi functional Solution for Industrial Counting and Rate Monitoring

In the field of industrial automation, accurate counting, speed measurement, and process control are key to ensuring production efficiency and product quality. The Ambassador 57600 series counting controller launched by Durant has become a core control device in various industrial applications due to its modular design, flexible programming capabilities, and strong scalability. This article is based on the official technical manual (document number: 57600-905-03), providing a systematic introduction to the functions, configuration, installation, and operation of this series of products.

Product Overview: Multi functional Integration and Modular Design

The Ambassador 57600 series is a six digit digital display, four preset value main counter, equipped with a single preset value batch counter, an eight digit digital display accumulator, and a 1/Tau rate meter. This series offers multiple models to meet different power and display requirements:

Power options:

57600-405 / 415 / 465：10–15 VDC

57601-405 / 415 / 455 / 465：115 VAC

57602-405 / 415 / 465：230 VAC

Display color: green or red LCD backlit display screen

Special models: 57601-415 (green) and 57601-465 (red) are foot/inch control versions with floating warning function.

The core design concept of this controller is "electronic building blocks" - users can "assemble" the required counter functions through programming according to specific application needs. The structural diagram clearly shows the logical relationship between the main counter, batch counter, accumulator, rate meter, output relay, control input, and RS-485 communication module.

Detailed explanation of core functions

Main Counter

Six digit digital display, bidirectional counting, supports up to four preset values. Users can customize the display unit text for easy on-site recognition. The counting direction can be programmed to "reset to zero" or "reset to final preset".

Batch Counter

Six digit digital display, unidirectional increment. Whenever the main counter automatically cycles or reaches the final preset value, the batch counter increments once. This counter has a preset value that automatically cycles once reached.

Totalizer

Eight digit digital display, bidirectional counting, synchronized operation with the main counter. Increase in the "preference direction" of the main counter, and decrease in the opposite direction. The accumulator has no preset or output function and is suitable for long-term data accumulation.

Ratemeter

Calculate the rate based on the pulse frequency of input A, supporting programmable scaling factors, average time, and zeroing time. Two alarm setpoints can be used for rate monitoring.

output module

Equipped with two Form C relays and two NPN open collector transistor outputs. Each output can be independently assigned to count or rate events, supporting delay, pulse, or latch modes.

Counting input and control input

Input A and B can be configured as current sinking or sourcing through DIP switches, supporting single ended or differential signals. The four control inputs can be programmed with 14 functions including reset, print, lock, stop counting, etc.

RS-485 serial communication

Supports host mode (responding to host commands) or printer mode (triggering print output). The communication parameters (baud rate, parity, ID number, etc.) are programmable.

Foot/inch control (special model)

The display format of the main counter is "feet inches", and the preset value is also entered in this format. The warning value will automatically adjust according to the final preset value to ensure ease of operation.

Installation and Wiring Guide

Terminal description:

Terminal 1: DC power input (10-15 VDC) or 12 VDC output (for powering sensors)

Terminal 2-4: DC common terminal

Terminal 5-10: Relay output (two sets, each set containing normally open, normally closed, and common terminals)

Terminals 11-12: AC power input (AC models only)

Terminals 13-14: Transistor output

Terminals 15-18: Control Input

Terminals 19-20: Counting inputs A and B

Terminal 21-22: RS-485 communication interface

General wiring requirements:

All power sources must be disconnected before wiring.

The counting and control signal lines should use shielded cables and connect the shielding layer to the common end.

Separate the wiring of signal lines and power lines to avoid interference.

It is recommended to use 18-14 AWG wire for the power cord and equip it with a fuse.

DIP switch settings:

Switches 1 and 2: Select input A/B as sink or source mode

Switches 3 and 4: Select high threshold (DC sensor) or low threshold (magnetic induction sensor)

Programming mode and parameter settings

Users can enter programming mode through the front panel keyboard and set the following parameters:

Scaling factor:

The counting scaling factor range is 0.00001 to 9.99999, used to convert input pulses into actual units (such as feet, gallons).

The rate scaling factor is calculated according to the formula RS=(SEC x DPF)/PPI, where SEC is the time unit (e.g. 60 represents per minute), DPF is the decimal factor, and PPI is the number of pulses per unit.

Decimal point position: The decimal point position for counting and rate display can be independently set.

Output behavior: Programmable to pick up (PU) or release (DO) based on preset values or rate alarm points, supporting delay and pulse width settings.

Display management: Users can choose which screens to display (main count, rate, batch, accumulator, preset value, etc.), and can customize unit text (up to 8 characters).

Reset and Print Keys: The reset and print keys on the front panel can be enabled or disabled, and the reset object (main counter, batch, accumulator, or all) can be selected.

Operation mode and operation

In operation mode, users can browse different screens by pressing the up and down keys, modify preset values by pressing the SEL key, and confirm modifications by pressing the ENT key. For the foot/inch model, the preset value input format is FFFF.II (the first four digits are feet and the last two digits are inches). The warning value will automatically track the final preset value to ensure early warning.

Fault diagnosis and self inspection

The controller has a power on self-test function. If a fault is detected, it will display ERROR X (X is 0-5) and stop all outputs. The fault code is as follows:

ERROR 0: ROM error

ERROR 1: Internal RAM error

ERROR 2: NOVRAM configuration data error

ERROR 3: Running data (count value, preset value) error

ERROR 4: User program parameter error

ERROR 5: External RAM error

For ERROR 3, press the reset button to reset the running data; For ERROR 4, press the reset button to restore the factory settings. If the problem persists, contact the manufacturer for repair.
