Replacement & Compatibility FAQ
Q: Can 140DAI75300 replace 140DAI74000 directly?
A: Yes, both are 32-ch 24VDC discrete input modules on the Quantum backplane. The 75300 variant supports higher input current sink/source flexibility. No software changes required.
Q: Is this module compatible with Modicon M340 or Premium?
A: No. The 140-series is exclusive to the Modicon Quantum backplane. For M340, refer to the BMX DDI series; for Premium, refer to TSX DEY series.
Q: What is the warranty on Konmask-supplied units?
A: All units carry a 12-month functional warranty from date of shipment. Extended warranty available on request.
Q: Can you supply the full Quantum I/O rack assembly?
A: Yes. Contact us with your BOM for a complete rack quotation including CPU, power supply, and I/O modules.
