Model 2024E Simplex or Multiplex BCD/Hex Interface

• Addressable, ideal for use with a PLC
• Binary coded decimal (BCD) or hexadecimal
• Sixteen 24 volt data lines, current-sourcing
• LEDs for each line indicate signal status
• Hand shaking lines
• Three Operating Modes for Tag reporting
• Mode 1 Simplex, 16 bits data in 4 hex characters
• Mode 2 Multiplex, 12 bits data in 4 hex characters + a 4 bit address
• Mode 3 Multiplex polling, 12 bits data in 4 hex characters + a 4 bit address
• Stores up to 8 readings
• Connection by Screw Terminals, 9 pin RS-232-C
• Compatible to all Readers via twisted pair
• CRC algorithm allows only 1 in 10 to the 14th errors
• Power by 24 VDC +/-25% @ 150 mA max
