Contact Data-Linc Group for an application review

Data-Linc Group’s DLM4100 voice band modem offers maximum versatility and reliability in remote process control and data acquisition. The DLM4100 series provides unsurpassed flexibility in dial-up applications.

The DLM4100 series uses advanced Trellis coding, error correction and data compression technology for virtually error free data communication. Uncompressed PLC line speeds are available between the port baud rates of 1200 to 19.2 Kbps.

The DLM4100 operates full/half-duplex on two wires. The asynchronous digital interface can be ordered as either RS232, AE485 or RS422 (AE485 Auto Enable function compatible with RS422/485). The DLM4100 auto-answer AE485 easily provides long distance polling of multiple PLCs at a remote site. The polling operation performed by the Master is completely transparent to the DLM4100. No additional Master programming is required— simply enter the Remote DLM4100 telephone number.

The DLM4100 is housed in a rugged steel enclosure for optimal EMI resistance or available in PLC slot-mount versions. TheDLM4100 is factory configured for trouble-free installation. No programming or configuration is required.

Industrial Applications

The DLM4100 series is ideal for industrial automation systems requiring:

  • PLC chassis mount communication devices
  • SCADA system communications
  • Remote PLC programming and diagnostics
  • PLC/RTU communications
  • Extended temperature ranges
