It can be expanded to 64 KB (requiring 1747-M13 memory module and 1747-M15 adapter).

Flash memory backup: Flash EEPROM.

I/O capacity:

Maximum discrete I/O: 4096 input + 4096 output.

Maximum analog I/O: 180.

Communication port:

One RS-232 port (supporting DF1 full/half duplex, Modbus RTU master/slave, ASCII, DH-485).

One DH-485 port.

Supported protocols: ControlNet, DeviceNet, Data Highway Plus (DH+), Ethernet (1761-NET-ENI required).

Performance:

Typical program scanning time: 1 ms/K (1 KB ladder diagram logic).

I/O scanning time: 0.225 ms.

Bit execution time (XIC) : 0.44 µs.

Power supply requirements:

Backplane current: 500 mA @ 5 V DC, 175 mA @ 24 V DC.

Program retention time after power failure: 20 ms to 3 s (depending on the power load).

Environmental requirements:

Operating temperature: 0°C to 60°C

Storage temperature: -40°C to 85°C.

Relative humidity: 5% to 95% (non-condensing).

Vibration: 2 g (10-500 Hz).

Impact: 30 g (in operation), 50 g (not in operation).

Battery

Battery life: Approximately 2 years (replaceable, with BATT LED low battery indicator).

After power failure, the capacitor retains data for at least 30 minutes.

Installation: Rack installation, compatible with SLC 500 chassis (1746-A4, A7, A10, A13, up to 3 chassis, 30 slots).

Certification: UL, C-UL, CE, C-Tick, Class I Div.2 (Group A/B/C/D, T4).

Function

High-performance control

Supports 107 programming instructions and is suitable for complex trapezoidal logic.

It can handle 4096 discrete I/O and 180 analog I/O, meeting the requirements of medium-sized automation.

Flexible communication

It has built-in RS-232 and DH-485 ports and supports multiple protocols (DF1, Modbus, DH-485).

It can be extended to Ethernet via 1761-NET-ENI and supports ControlNet, DeviceNet, etc.

Modular expansion

Supports 60 types of I/O modules (digital, analog, intelligent), with a maximum of 3 chassis and 30 slots.

Configurable memory is used for program or data storage.

Reliable storage

Battery backup RAM (with a lifespan of 2 years), supports Flash EEPROM to prevent program loss.

It can be expanded to 64 KB through the 1747-M13 module.

Operating mode:

A 3-key switch (PROGRAM, RUN, REMOTE) makes it convenient to switch the running status.

The LED indicator lights (operation, fault, communication, battery status) support real-time diagnosis.

Programming support:

The RSLogix 500 software is used, which supports ladder diagram programming and point-of-click I/O configuration.

Application scenarios

Manufacturing industry: Control conveyor belts, sorting systems and assembly lines, suitable for small and medium-sized production lines.

Packaging and material handling: Manage packaging machines and palletizing equipment, and support high-speed I/O processing.

Food and Beverage: Control filling, mixing and packaging processes to ensure production efficiency.

Process control: Used in water treatment, chemical and pharmaceutical industries to monitor temperature, pressure and flow.

Building automation: Manage HVAC, lighting and energy systems, and support remote communication.

OEM equipment: Integrated into specialized machinery (such as printing machines, textile equipment), providing cost-effective control.

Typical applications:

Small and medium-sized automation systems require high I/O capacity (4096 discrete I/O) and network connections.

Distributed control, combined with Ethernet modules to achieve SCADA or HMI integration.
