AEG AS-B809-016 16‑Channel 230 VAC Digital Input Module
- Product Introduction: It is a 16‑channel digital input module belonging to the AEG Modicon 800 series, designed to collect 230 VAC switching signals from industrial field devices like limit switches, pushbuttons, and circuit breakers, and convert them into logic signals that can be identified by the PLC CPU for subsequent control logic operation.
- Technical Specifications:
- Input Channels: 16 independent digital input channels, divided into two common groups of 8 channels each.
- Input Voltage: 160‑260 VAC, 47‑63 Hz; surge voltage: 400 VAC for 1 cycle, 300 VAC for 10 seconds.
- Turn‑on Threshold: 112‑148 VAC; Turn‑off Threshold: 0‑90 VAC.
- Typical Wetting Current: 8.5 mA at 230 VAC.
- Response Time: ≤20 ms (on and off).
Detailed content
-
- Isolation: 2500 VAC isolation between channels and between channels and the backplane.
- Power Supply: 24 VDC, power consumption of 3.5 W.
- Operating Temperature: -25°C to +70°C; Protection Rating: IP20; Dimensions: 120mm × 160mm × 50mm (W×H×D).
- Functional Features:
- Each channel has an independent LED indicator, which can visually display the on/off status of the input signal for quick troubleshooting.
- Built‑in filter circuit effectively suppresses high‑frequency interference in the industrial field and ensures stable signal collection.
- Supports dry contact input, compatible with various standard 230 VAC switching devices without additional signal conversion.
- It can be installed on a standard DIN rail, and the screw terminal wiring method is adopted to facilitate installation and maintenance.
- It is fully compatible with the AEG Modicon 800 series PLC chassis and can be flexibly combined with other modules to expand the system input capacity.
- Application Scenarios: Widely used in industrial control systems such as high‑voltage motor control cabinets, power distribution automation, and large‑scale water treatment equipment. It is used to collect high‑voltage side switch signals to realize interlock protection, sequence control, and fault alarm functions of the system, and is especially suitable for industrial occasions with 230 VAC field signal distribution.
