• DL205 - If your application requires the flexibility of a modular control system, a DL205 PLC is the lowest cost, most versatile solution you'll find. In fact, all you need to do is pick out a CPU card, plug it in the first slot of the base you choose, and then mix and match various modules into the available slots. The DL205 features:
  • Four base sizes with built-in power supply, including 12/24 VDC, 110/220 VAC and 125 VDC power.
  • AC/DC discrete in/out, up to 32 points
  • Ten amp relay out
  • 12-bit and 16-bit analog inputs and outputs
  • Temperature inputs
  • Data communications, including serial and Ethernet modules
  • Counter input/pulse output
  • Remote I/O master and slave
