Overview
FAQ:
1.Which expansion modules can 1763-L16BBB be connected to? What is the maximum number of I/O points that can be expanded?
- Supported module types: digital input/output/mixed I/O, analog I/O, ASCII communication, RTC and other special function modules.
- Expansion restrictions: Up to four 1762 modules can be cascaded. The host comes with 18 I/O points, and the total number of points does not exceed 128 points.
2. How many expansion modules can be connected to 1763-L16BBB?
1763-L16BBB can connect up to 4 expansion modules and is only compatible with 1762 series expansion modules.
This limitation is determined by the PLC’s bus drive capability and hardware design. The total I/O points of the four expansion modules need to be controlled within 128 points to meet the functional expansion needs of small automation scenarios.
3.What is the specific I/O structure of 1763-L16BBB?
The I/O structure of 1763-L16BBB is “integrated fixed + expansion compatible”:
- Integrated I/O: 10 24V DC digital inputs (0-3 high speed), 2 analog inputs (0-10V/4-20mA), 6 digital outputs (2 relays + 4 DC FETs).
- Expansion I/O: supports 4 1762 series modules, total I/O≤128 points.
- Address allocation: Digital I/O starts from I:0/0, O:0/0, analog input starts from AI: 0.0, and the expansion module address increases in sequence.
