KEBA AR‑181

Signal type: 24 V DC digital input; PNP transistor digital output. Channel configuration: 8 digital input channels and 8 digital output channels. Each output channel maximum load current is 0.5 A. Input‑output response time is less than 1 ms. Power‑supply requirement: 24 V DC. Operating temperature ranges from ‑10°C to +60°C. Protection rating is IP20, for cabinet‑internal installation. Installation methods support DIN‑rail mounting and slot‑type backplane mounting. Each channel is equipped with status LED indicator.

High‑speed discrete signal collection and output. LED status indicator for every input and output channel for on‑site fault diagnosis. Transistor‑type PNP output for driving field actuators. Short‑circuit protection for output channels. Real‑time signal transmission with KEBA main controller via system backplane bus. Compact structure saves control‑cabinet space. Supports modular expansion of I/O quantity. Supports reading channel diagnostic information by upper‑level control software.

Injection‑molding machine automation control, industrial robot peripheral signal processing, packaging machinery logic control, automated assembly workstation, pneumatic‑hydraulic actuator signal control, general‑purpose industrial equipment discrete‑signal acquisition and output.

Input‑output response time below 1 ms ensures real‑time logic action. Output channel withstands transient overload protection. LED reflects real‑time on‑off state of each channel. Backplane bus realizes high‑speed data exchange with main controller.

Industrial‑grade plastic module housing, FR‑4 printed circuit board, gold‑plated system backplane connector, screw‑type terminal blocks, transistor output drive chips, optocoupler isolation components, status LED indicators, over‑current and surge‑protection components.

Standard modular I/O form factor. Back‑side backplane connector connects to KEBA controller rack bus. Front‑side screw terminal blocks for field‑signal wiring. Each channel corresponds to one LED indicator on front panel. Supports DIN‑rail independent installation or insertion into controller rack slot.

Field 24 V DC digital input signal is isolated by optocoupler and sampled by module circuit. Sampled digital status data transmits to KEBA main controller through backplane bus. Control logic result from main controller is sent back to AR‑181 module. Module drives PNP transistor output circuit to output 24 V DC switch signal to field actuators. Each channel status LED synchronously lights up according to actual signal state. Internal hardware circuit monitors output over‑current condition and activates protection when short‑circuit occurs.

Install module on DIN‑rail or insert into designated slot of KEBA controller rack. Ensure reliable contact of backplane connector. Complete field‑signal wiring on front‑side screw terminals, distinguish input signal terminals, output signal terminals and 24 V power terminals. Tighten terminal screws with proper torque. Confirm 24 V DC power‑supply specification matches module requirement. Keep sufficient heat‑dissipation space inside control cabinet.

Module is IP20 rated and must be installed inside control cabinet. Do not exceed 0.5 A maximum current per output channel. Inductive load must be connected with free‑wheeling protection circuit externally. Configure I/O mapping parameters in KEBA programming software after hardware installation. Observe front‑panel LED indicator for on‑site troubleshooting. Operate within ‑10°C‑+60°C operating temperature range. Avoid conductive dust accumulation on module terminals.
