140EHC10500 Schneider Relay Module
140EHC10500 is a high-speed counter module launched by Schneider Electric, belonging to the Quantum automation platform. The module is equipped with five channels, supports discrete incremental counter inputs, and can achieve pulse counting up to 100kHz at 5V or 24V voltage. It is also equipped with four operating modes: 32-bit event counter, 32-bit differential counter, and 16 bit repeat counter. The count value is transmitted in real-time to the CPU through asynchronous update mechanism, making it suitable for high-speed pulse counting scenarios. The module adopts a modular design, supports local rack installation, is equipped with five LED channel status indicator lights, and has address requirements for 12 input words and 12 output words. The working voltage is 30V DC, the maximum input current is 7mA, the output voltage range is 20-30V DC, the load current is 0.21A, and the insulation strength between each channel and the bus reaches 500Vrms (60 seconds). It integrates output short-circuit protection function, with a power consumption of ≥ 6W and a bus current requirement of 250mA. When powered externally, the 24V DC current consumption is ≤ 1140mA. The product has passed multiple international certifications such as ABS, CSA, C-Tick, DNV, GL, GOST, LR, RINA, RRS, UL, etc., ensuring reliable operation in industrial environments.
