WAGO 750-833 – PROFIBUS DP/V1 Controller (Slave) Overview The WAGO 750-833 is a stand-alone PROFIBUS DP/V1 controller (slave) that combines CPU, fieldbus communication, and I/O interface in one device. It supports IEC-61131-3 programming languages and allows the user program to access both the fieldbus data and local I/O data. It is suitable for decentralized control, reducing load on a central PLC, performing preprocessing at the field level, and maintaining compact installations. Key Features PROFIBUS DP/V1 slave communication IEC-61131-3 compliant programming (IL, LD, FBD, ST, SFC, CFC) Fast cycle time (< 3 ms under typical load) Supports up to 63 I/O modules per node High data capacity: process image up to 244 bytes in / 244 bytes out Rotary or DIP configuration for node address, baud rate etc. LEDs for status: RUN, Bus Fault, Diagnostics, I/O, etc. Field supply and system supply isolation (≈ 500 V) Technical Specifications Part Number: 750-833Device Type: PROFIBUS DP/V1 Controller (Slave)CPU: 16-bitProgram Memory: ≈ 128 kBData Memory (RAM): ≈ 64 kBNon-Volatile Software Memory: ≈ 8 kBFieldbus Input Process Image: Max 244 bytesFieldbus Output Process Image: Max 244 bytesMax Number of Fieldbus I/O Modules: 63Max Number of I/O Points: up to 6,000 (with proper setup)Baud Rate: 9.6 kBaud … 12 MBaudBus Segment Length (max.): ~1,200 mSupply Voltage (System, local CPU): 24 VDC (-25 % … +30 %)Field Supply Voltage: 24 VDC via power jumper contactsCurrent Consumption (System 5 V Side): ~200 mACurrent Consumption (24 V Field Side, under load): ~500 mAPower Jumper Contacts Capacity: ~10 AIsolation Voltage between System vs Field: ~500 VConnection Types: D-Sub 9-pin for PROFIBUS; CAGE-CLAMP® for system and field supplies; Male 4-pole for configuration connectorSolid / Stranded Conductor Size: 0.08 … 2.5 mm² (AWG 28 … 14)Wire Strip Length: ~8 … 9 mmWidth: ~50.5 mmHeight: ~100 mmDepth: ~71.1 mmHeight from Top Edge of DIN Rail: ~63.9 mmOperating Temperature: 0 °C … +55 °CStorage Temperature: -25 °C … +85 °CProtection Rating: IP20Pollution Degree: 2 Applications PROFIBUS DP slave nodes in distributed industrial systems Decentralized I/O control with preprocessing to reduce master load Environments needing mixed digital/analog I/O with high data capacity Applications where compact local control and fault-tolerant status are needed Why Choose the WAGO 750-833 Combines fieldbus control and local I/O in one unit, saving on hardware and wiring High process image capacity for large I/O layouts Good performance at high baud rates with proven stability Strong isolation protects system electronics from field disturbances Wide industrial certification and mounting flexibility Order Now The WAGO 750-833 is part of the WAGO I/O System 750 product line and is available for purchase.
