ICP DAS I-7055D-NPN - I-7055-NPN with display
by ICP DAS
|
|
|
|
RS-485 data acquisition module with 8-channel Isolated Digital Input (Counter) and 8-channel Isolated Digital Output. Supports operating temperature of -25°C ~ +75°C (-13°F ~ +167°F)
|
|
|
The I-7055D-NPN offers 8 isolated channels for digital input and 8 isolated channels for digital output. Either sink-type or source-type digital input can be selected via wire connections. All digital input channels are also able to be used as 16-bit counters. The I-7055D-NPN supports source-type output with short circuit protection. There are options to enable both power-on and safe values. The I-7055D-NPN has 16 LED indicators that can be used to monitor the status of the digital input and digital output channels. 4 kV ESD protection and 3750 VDC intra-module isolation are standard. I-7055D-NPN provides additional support for the Modbus RTU protocol as well as the DCON protocol.
