Product Description
It accepts no-voltage contacts or NPN/PNP sourced signals at 24VDC, with each input independently photoelectrically isolated and a configurable 0.8-51.2 ms response filter. Beyond the parallel expansion bus, the built-in Ethernet (RJ45) and RS485 ports let it act as a distributed remote I/O node. Mounted on a 35 mm DIN rail (131x95x82 mm), it collects field signals from switches, sensors, and pushbuttons across spread-out installations. The H40DI-E is a 40-point digital input expansion module in the Haiwell H-series, designed to add discrete sensing capacity to compatible PLC systems.

Frequently Asked Questions
What is the difference between H40DI and H40DI-E?
The H40DI-E adds a built-in Ethernet (RJ45) port for remote I/O and cloud access; the base H40DI uses RS485 only. Both offer 40 digital inputs.
What input wiring is supported?
It accepts no-voltage dry contacts or NPN/PNP sourced 24VDC signals, with an ON threshold above 3.5 mA and per-channel photoelectric isolation.
Can the input filter time be adjusted?
Yes. The response filter is configurable from 0.8 ms to 51.2 ms per the application, with a 6.4 ms default.
How is the module powered?
It is powered from the host PLC's internal 24VDC expansion bus, or from an external 24VDC supply (approx. 0.07 A) when used as a remote I/O node.
