features and benefits
The PROFI-8255 Remote I/O Unit is specially designed for the slave device of PROFIBUS DP protocol.
It supports up to 2 slots for ICPDAS I-8k series, I-87k Low Profile series, and I-87k High Profiles series I/O modules.
In addition, we also provide hot-swap function for I-87k High Profiles series I/O modules.
To setup network, users can choose and configure I/O modules by using the GSD file without any other setting tools.
- Protocol & Hierarchy : DP-V0 & DP-V1 (Read/Write) Slave
- Transmission Rate Setting : detected automatically
- Address Setting : 0~126 set by Rotary switches, SSA-telegram set by DP-Master(Class 2 only)
- I/O modules Configuration : Configured by GSD file
- Supports I/O modules hot-swap : I-87K High Profile series
- Network Isolation Protection : High Speed iCoupler
- DC Isolation Protection : 3000VDC on PROFIBUS side
- 4KV ESD Protection : Contact for each terminal
