Function

Modular design: Supports up to 3 local I/O racks and 30 I/O module slots, suitable for medium-sized control systems, and easy to expand and customize.

Communication interface:

The DH+ port supports high-speed, long-distance and multi-point topologies, making it suitable for distributed I/O applications.

The RS-232 port supports DF1, DH-485, ASCII and Modbus RTU, and can be connected to the multipoint network through the 1761-NET-AIC converter.

Memory backup: Supports optional EEPROM modules (1747-M1, 1747-M2) for non-volatile storage to prevent program loss due to power fluctuations or battery depletion.

Status indication: Equipped with LED indicator lights (RUN, CPU FAULT, FORCED I/O, BATTERY LOW, RS-232, DH+), facilitating fault diagnosis and status monitoring.

High performance: It offers fast program execution (0.9ms /K) and I/O scanning (0.225ms), supports advanced instruction sets, including indirect addressing, advanced mathematical operations, PID control, program interrupts, etc., and is suitable for complex control logic.

Remote I/O support: Supports remote I/O configuration, with a maximum capacity of 4096 input and 4096 output, suitable for distributed control systems.

Programming support: Using RSLogix 500 software, it supports ladder diagram programming, provides point-to-point I/O configuration and a powerful database editor.

Application scenarios

Material handling: Control equipment such as conveyor belts and automatic guided vehicles (AGVs).

HVAC control: Used for heating, ventilation and air conditioning control in building management systems.

Medium-sized process control: Applicable to process control of medium-sized production lines, such as pumps, valves or process equipment.

Assembly operation: Control the automated assembly line or robot workstation.

SCADA system: As a controller in a distributed control system, it performs data acquisition and control tasks.
