Information About 1756-L61
The 1756-L61 belongs to the ControlLogix family of controllers, offering high-performance processing and flexible system integration. Installed in any slot of a 1756 chassis (A4, A7, A10, A13, A17), it provides modular scalability for diverse control applications. The controller supports up to 128,000 digital and 4,000 analog I/O points. It allows up to 32 tasks and 100 programs per task, with event task triggering for responsive applications. An RS-232 serial port provides direct communication using DF1 full/half duplex, ASCII, DF1 radio modem, Modbus (via logic), and DH-485 protocols. Non-volatile memory is available through a 1784-CF128 CompactFlash card for up to 128 MB of storage. The module also supports removal and insertion under power (RIUP), enhancing maintainability. With programming flexibility across ladder logic, structured text, function block, and sequential function charts, the 1756-L61 is well-suited for complex automation systems.
Key Features:
- Design: ControlLogix 5561 chassis-based programmable automation controller.
- Memory: 2 MB user memory and 478 KB I/O memory; expandable with 1784-CF128 CompactFlash.
- Connections: Supports up to 250 controller connections.
- I/O Capacity: 128,000 digital I/O, 4,000 analog I/O, 128,000 total I/O points.
- Processing: 32 tasks and 100 programs per task with event task triggering.
- Communication: Built-in RS-232 port supporting DF1, ASCII, DH-485, Modbus (via logic).
- Networks: Compatible with EtherNet/IP, ControlNet, and DeviceNet via communication modules.
- Programming Languages: Supports ladder logic, structured text, function block, and SFC.
- Maintenance: Supports removal and insertion under power (RIUP) and replaceable battery backup.
- Chassis Compatibility: Works with 1756-A4, A7, A10, A13, and A17 chassis.
The 1756-L61 delivers robust performance and flexibility, making it a reliable choice for high-demand industrial automation applications.
