I-87040W

The I-87040W/I-87040PW offer 32 channels for digital input, each of which features photocouple isolation. Either sink- or source-type input can be selected via wire connections. All channels are able to be used as 16-bit counters and 32 LED indicators that can be used for monitoring DI channel status are also provided, together with 4 kV ESD protection and 3750 VDC intra-module isolation. Paired with a daughter board such as the DN-37-381-A, wiring is easier than ever. The I-87040PW is suitable for +24 VDC digital input systems and provides noise protection capabilities that enhance noise immunity in industrial environments. ICP DAS recommends selecting the “p” version of the digital input module for industrial use.
