SCADALink IP100 for Modbus TCP and Modbus RTU I/O Expansion

Often in new or legacy automation applications there is a requirement to add local or remote I/O.

Modbus TCP, and Modbus RTU protocol is a common protocol supported by almost all SCADA Software, DCS, PLC, RTU, and Flow Computer manufacturers.

Supporting Modbus TCP and Modbus RTU Protocols; and having I/O bus,  the SCADALink IP100 can be a used for I/O expansion in new or legacy systems.

The SCADALink IP100 supports connectivity to up to 10 SCADALink Modular I/O modules of any type including:

  • DI8  – 8 Dry Contact Inputs
  • DO8 –   8 Relays Output
  • AI4  – AI4 – 4 x Isolated 4-20ma Output
  • AO4 – 4 x Isolated 4-20ma Output
  • COMBO-I/O – 2 DI/2DO,1 AI, 1 AO .

SCADALink I/O Expansion Modules integrated with the IP100 are mapped as a single Modbus device (Modbus TCP or RTU).

SCADALink I/O Expansion Modules featuring isolated I/O, low power 10-30 VDC operation, Class I Div 2 certification, and standard Modbus protocol support is an ideal I/O expansion solution for remote RTU applications where the RTU or Flow Computer is out of I/O.

In addition, the SCADALink IP100 can also be used as a Modbus Ethernet-Serial Gateway for RS485 and RS232 instrumentation/devices at remote sites.
