AEG OUTPUT B824 16-Channel 24 VDC Digital Output Module
- Product Introduction: It is a classic 16-channel DC digital output module of the AEG Modicon 800 series, specially used to convert the digital control signals output by the PLC CPU into 24 VDC switching signals, drive various low-voltage industrial field actuators, and is the key execution interface of the PLC control system to connect the on-site equipment.
- Technical Specifications:
- Output Channels: 16 independent digital output channels, divided into 4 common groups of 4 channels each, supporting independent on/off control of each channel.
- Output Type: Sourcing output (PNP type), compatible with most 24 VDC DC actuators on the market.
- Rated Output Voltage: 24 VDC ±10%; Maximum Output Current: 2 A per channel, 8 A per common group.
- Output Response Time: ≤5 ms (on), ≤3 ms (off); Drop-out Voltage: ≤1 VDC.
- Overload Protection: Each channel is equipped with overcurrent and short-circuit protection, and the protection current is 2.5 A ±0.2 A, which automatically recovers after the fault is removed.
Detailed content
-
- Isolation: 2500 VAC isolation between channels, between common groups and between the module and the backplane bus.
- Power Supply: 24 VDC (power supply for the module itself), power consumption of 4 W; Output power supply: independent 24 VDC (external), supporting separate power supply for different common groups.
- Operating Temperature: -25°C to +70°C; Storage Temperature: -40°C to +85°C; Protection Rating: IP20; Dimensions: 120mm × 160mm × 50mm (W×H×D); Installation Method: Standard 35mm DIN rail installation.
- Functional Features:
- Each channel is equipped with an independent LED status indicator, which is on when the output is on and off when the output is off, realizing visual monitoring of the output status and facilitating quick troubleshooting of on-site equipment faults.
- Built-in freewheeling diode protection circuit for each output channel, which effectively absorbs the reverse electromotive force generated by inductive loads (such as relays, solenoid valves, contactors) when they are disconnected, and protects the module output transistor from being damaged.
- The modular design with screw terminal wiring is adopted, the wiring is firm and reliable, and the disassembly and assembly are convenient, which is suitable for the harsh wiring environment of the industrial field and reduces the maintenance time.
- Supports hot swapping function, which can replace the module without shutting down the PLC system and cutting off the power supply, effectively reducing the downtime of the production line and improving the system availability.
- The output circuit adopts high-reliability power transistor, with a service life of more than 100 million switching times, which ensures the long-term stable operation of the module in the continuous working environment of the industrial field.
- Fully compatible with all AEG Modicon 800 series PLC chassis and backplane buses, and can be flexibly combined with other digital/analog input modules, communication modules and counter modules to form a complete control system.
- Application Scenarios: It is the most commonly used output module in AEG Modicon PLC control systems, and is widely used in various industrial automation fields such as factory automation, building automation, process control and municipal engineering. It is used to drive 24 VDC low-voltage actuators such as solenoid valves, relays, contactors, indicator lights, small DC motors, and electromagnetic clutches. Typical application scenarios include packaging machinery actuator control, automatic assembly line solenoid valve switching, water treatment equipment valve control, intelligent building lighting and fan control, and chemical plant on-site indicator light control.
