The DL305 features specialty modules such as ASCII/ BASIC modules, high-speed counter modules, and
communication interface modules. Available specialty modules include:
F3-AB128, F3-AB128-T and F3-AB128-R ASCII modules
The ASCII/BASIC module interfaces the DirectLOGIC 305 family of programmable controllers with barcode
readers, operator interface terminals, instrumentation equipment, computers and other serial devices.
The three ports offer a range of communication interfaces and baud rates. The ASCII/BASIC modules require
the use of a D3-330 or 340 CPU. They are not supported by the D3-350 CPU.
D3-TCSU Timer/Counter Setpoint Unit
The DL305 Timer/Counter Setpoint Unit (TCSU) is compatible with all D3-330/340 series CPUs that provides a
low-cost solution for changing timer/counter preset values or register data. This unit has four sets of
thumb wheels that allow you to quickly and easily change the presets for four predefined timer/counter
registers, or 4 predefined data registers. This unit attaches to the CPU and power supply. It utilizes
internal base power, so make sure you take this into consideration when you calculate your system power
budget. The D3-TCSU uses the D3-TCSUBKT mounting bracket.
