Product Description:
The KS1114 digital input module is manufactured by Beckhoff and belongs to the KS Digital Input Modules series. Designed for decentralized control cabinets, it collects on/off sensor states and forwards them to a PLC through the internal I/O bus. By translating field-level contacts into logic-level signals, the unit forms a compact gateway between switches, proximity sensors, or photoelectric devices and the higher-level automation controller. Its role is to provide electrically isolated, debounced detection of machine status points, enabling deterministic processing within cycle-critical tasks. This arrangement lets the PLC evaluate limit switches, sensor confirmations, and interlock contacts without separate signal-conditioning hardware.
The module offers 4 discrete input channels, each referenced to the 0 V power contact. A built-in filter of 0.2 ms suppresses contact bounce so the controller only sees stable transitions. All channels operate from a 24 V DC nominal level, matching the standard control voltage found in most machinery. The input circuitry satisfies EN 61131-2 Type 1, which provides defined current draw for reliable sensor activation. The housing latches onto a 35 mm DIN rail, allowing quick addition to existing terminal rows. An internal process image exposes four input bits to the fieldbus master, and the wiring level is pluggable for orderly field connections.
The module has an IP20 protection rating, so it is intended for use inside closed enclosures while still providing touch protection. The polycarbonate housing measures 12 x 100 x 68 mm, conserving panel space when many modules are lined up. Through the power contacts, the segment can distribute up to 10 A, eliminating separate feed lines for neighboring I/O terminals. Sensor leads can be landed with a 2-wire or 3-wire scheme, and side-mounted double-slot and key connectors maintain bus continuity while allowing flexible installation orientation. The slim width also helps preserve cabinet space when multiple I/O terminals are mounted in a dense row.
