Schneider Electric TXS Quantum 140 EHC 105 00 5 HI Speed CTR 20 100KHZ

The Schneider Electric Modicon Quantum 140EHC10500 high‑speed counter module adds five independent counters to a TSX Quantum/Modicon Quantum controller, enabling precise pulsed counting up to 100 kHz on 5 V inputs (per channel) or 20 kHz on 24 V inputs across five channels. Each channel can operate as a 32‑bit event counter with configurable output, a differential counter, a 16‑bit repetitive counter, or a 32‑bit rate counter, while the module provides eight isolated 24 VDC inputs and eight isolated 24 VDC outputs for companion I/O. The 140EHC10500 is powered from the Quantum backplane at 5 VDC, with the isolated I/O and counter inputs fed from an external 24 VDC supply; a green LED indicates the 24 V supply is present, and a short‑circuit‑proof output design protects connected devices. Data reporting to the CPU occurs on every scan, with asynchronous updates possible when the module is in a local rack, and configuration is performed from the CPU using Concept, ProWORX32, or EcoStruxure Control Expert (formerly Unity Pro/Concept). Connectivity on the front panel is via a removable 40‑way terminal block (orderable as 140XTS00200 or 140XTS00100). Typical applications include high‑speed encoder pulse counting, flow or rotation speed measurement, and event/rate counting in automation tasks such as packaging lines and conveyors where reliable multi‑channel pulse counting up to 100 kHz is required.
