I-87040W-G CR: Module 32 kênh đầu vào số DI


• Sink- or Source-type Digital Inputs
• Photocouple Isolation
• All Channels can be used as 16-bit Counters
• Optional Daughter board connectivity
• 4 kV ESD Protection
• 3750 VDC Intra-module Isolation
• D-sub DB37 Wiring
• Dual Watchdog
• RoHS Compliant
• Wide Operating Temperature Range: -25 ~ +75°C


The I-87040W 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.
