The I-87041W/I-87041PW module offers 32 Digital Output channels, each of which features Photocouple isolation and supports sink-type output using an open collector. The I-87041W/I-87041PW includes 32 LED indicators that can be used to monitor the status of the Digital Output channels, and options are available for confi guring both power-on and safe values. 4 kV ESD protection and 3750 Vrms intra-module isolation is provided as standard. The I-87041W/I-87041PW can be paired with a daughterboard, such as the DN-37-381-A for easy wiring, or the DN-8K32R for relay output.

The I-87041PW integrates over-current, over-voltage and short-circuit functionality. ICP DAS recommends selecting either the "PW" version of the digital output module for industrial use.
