Schneider Electric S48896 Programmable Logic Controller Module

The S48896 is a compact, all-in-one PLC module from Schneider Electric's Modicon series. It integrates a CPU with 24 digital inputs (24 VDC), 16 digital outputs (relay), and 2 analog inputs (0–10V). The module features a 32-bit processor with 256 kB of program memory and 128 kB of data memory. A built-in Ethernet port supports Modbus TCP and web server functions, while an RS485 port offers Modbus RTU for connecting external devices.

Performance Specifications

• Execution Speed: 0.07 µs per boolean instruction

• Program Memory: 256 kB (retainable up to 64 kB)

• Data Memory: 128 kB (retainable with supercapacitor backup)

• I/O Scan Time: 1 ms for digital, 2 ms for analog

• High-Speed Counters: 4 channels, up to 100 kHz

• Real-Time Clock: with drift ±2 seconds/day

Communication and Networking

The integrated Ethernet port (10/100 Mbps) supports Modbus TCP client/server, EtherNet/IP adapter (optional firmware), and embedded web server for diagnostics. The RS485 port (isolated) can be configured as Modbus RTU master or slave. Additionally, a USB mini-B port is used for programming via EcoStruxure Machine Expert (SoMachine) software.

I/O Features

Digital inputs are 24 VDC sink/source, with a filter adjustable from 0.1 to 12 ms. The 16 relay outputs are rated at 2 A per point (240 VAC/30 VDC). The two analog inputs (0–10 V) have 10-bit resolution. The module also includes two fast transistor outputs (PWM/PTO up to 100 kHz) for stepper control. Expansion is possible via a right-side bus connector, adding up to 7 I/O modules (digital, analog, temperature).

Physical and Environmental

Dimensions: 90 mm × 70 mm × 55 mm (W × H × D). Weight: 0.22 kg. Mounting: DIN rail (35 mm) or panel screws. Operating temperature: -20°C to +60°C; storage: -40°C to +85°C; humidity: 10–95% non-condensing. Protection rating: IP20. Power supply: 24 VDC (19.2–28.8 V), consumption 200 mA typical. The module includes a replaceable battery for real-time clock (CR2032).

Applications

Ideal for small machinery, conveyor control, HVAC, and packaging machines. The S48896 can be programmed in ladder diagram (LD), function block (FBD), or structured text (ST). It supports up to 32 Modbus devices on the RS485 network, making it suitable for distributed sensor networks.
