  • 229 instructions, including 8 PID loops
  • Two communication ports, including RS232/ 422/ 485 capability
  • Supports networking for MODBUS RTU master/slave, ASCII in/out, a DeviceNET slave option module, and an Ethernet option module
  • Integrated high-speed inputs and pulse output
  • Built-in real-time clock/calendar
  • Optional LCD display for operator interface or maintenance troubleshooting
  • Four option card slots accept discrete, analog I/O, high-speed counting/ pulse output and communication modules

• 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

• DL305 – This PLC design has been marketed by various name-brand PLC manufacturers for over 17 years. It has masqueraded as the General Electric Series One, the Texas Instruments Series 305, and the Siemens SIMATIC TI305. It features:
  • Four standard CPUs to choose from, including the D3-350 ($209) with PID control and two communication ports
  • Standard CPUs programmed with handheld programmer or Windows-based software
  • Specialty CPUs convert a DL305 system into an RTU for Optomux, Pamux, or allow BASIC programming for custom applications
  • Five, eight, and 10-slot bases
  • 110/220 VAC or 24 VDC power supply
  • AC, DC inputs
  • AC, DC, and relay outputs
  • Eight or 12-bit analog input/output
  • Specialty modules include ASCII/BASIC module, high speed counter, and communication interface module
