External 8CH Self-protecting Analog Expander Input Module (31000535)

Features

• Compact design.
• Wide power supply range.
• Low current consumption.
• 8 self-protecting analog inputs.
• Dedicated RS-485 port for slave device connection or HMI connection, can be configured as required.
• Expansion port daisy chain connections. Daisy chain can be broken and a new device chain established by simple jumper configuration.
  This option is useful if more than 32 devices are on the network, as this card can be configured to split the chain and establish a new chain as a secondary master.
  (Dedicated RS-485 port will not be available when this option is used).
• 256KB of PLC ladder logic program memory.
• 32KB of RAM for program execution, and variable storage.
• Micro SD Card Slot for program updates, and variable log storage (if programmed).
• While this device is listed as a simple expansion card, it is actually a fully functional independent PLC with its own onboard core processor.
  And as such, it can be independently programmed to perform its own tasks, routines, and programs. Once these tasks are completed, it can then report the results of these tasks back to the master PLC via the Modbus expansion daisy chain network.
  Alternatively, this device can be used as a stand-alone PLC, with a core functionality of 8 self-protecting analog inputs,
  while further expansion I/O or sensors can be added via the dedicated Modbus RS-485 port.
