Product Short Description
Product Name
KEBA AR-181 Analog Input Module (Kemro / KeControl Series).
Product Overview
The KEBA AR-181 is an analog input module produced by KEBA for KEBA series control systems. It acquires multi-channel analog voltage and current signals from field sensors and converts them into digital process variables for the machine controller, commonly deployed in injection molding, robotics, and packaging automation.
Description
Technical Specifications

Functional Features
- 8-channel analog voltage input acquisition with 12-bit resolution
- 1 ms update rate for fast process loops
- Supports multiple input ranges for flexible sensor interfacing
- Internal filtering and optical isolation reduce common-mode noise from nearby servo drives
- Front-panel diagnostic LEDs indicate power, bus communication, and channel faults
Application Scenarios
Hydraulic pressure feedback in injection molding presses, distance/position sensing in packaging machines, and sensor integration in robotics cells or general KEBA Kemro/KeControl automation racks.
Performance Parameters
12-bit A/D conversion; 1 ms scan/update; multi-range input selection; 24 V DC powered.
Material Composition
Modular plug-in card with conformal coating; screw/spring terminal blocks; backplane connector for KEBA bus (specific PCB laminate not specified).
Structural Characteristics
Open-board modular housing with conformal coating; DIN-rail or dedicated KEBA rack mounting; secure locking terminal blocks that resist vibration-induced loosening.
Working Principle
Raw analog sensor signals (voltage/current) enter via terminal blocks, pass through internal filtering and isolation, get digitized by the 12-bit ADC, and travel over the high-speed KEBA internal backplane bus to the controller.
Installation Requirements
Snap onto DIN rail or insert into KEBA rack; wire analog sensors to terminal blocks observing correct polarity and shield grounding; ensure 24 V DC supply is stable; verify addressing in project software.
