Our PLC prices are hard to beat!
The DirectLOGIC 405 PLC process control system from Koyo packs a lot of power for its size and price.
It is one of our most powerful PLC applications. The DL405 PLC control system has the one of the widest varieties of I/O modules and configurations of all our DirectLOGIC PLCs.
You can build a PLC controller system with local/distributed I/O of up to 3,500 points. Use the built-in PID instruction or specialty modules to perform cost-effective process control.
How the PID PLC Application Works:
PID (Proportional, integral, derivative) control: The control algorithm that is used to closely control processes such as temperature, mixture, position, and velocity.
The proportional portion takes care of the magnitude of the error.
The derivative compensates for the rate of error change.
The integral takes care of small errors over time.
The DL405 PLC controller system features include:
- Three CPUs from 6.5 K memory with 1,152 I/O to 30.8 K memory with 3,584 possible I/O, with built-in power supply
- Three base sizes
- AC/DC in/out, up to 64 points
- Ten amp relay out
- 12-bit and 16-bit analog inputs and outputs
- Thermocouple and RTD inputs
- Data communications, including serial and Ethernet modules
- High-speed counter input and pulse output
- Serial remote I/O master and slave modules
- Ethernet remote I/O master and slave base controllers
- Slice I/O master and slave modules
Discrete modules in 8, 16, 32 and 64-point I/O densities
Use our ZIPLink pre-wired I/O cables and connector modules for easy wiring, especially to our 64-point DC modules.
Wide range of analog modules
Our analog I/O selection will give you the flexibility you need to perform low-cost process or data acquisition applications. We have 4, 8 and 16-channel models with input and output ranges such as 4-20 mA, 0-10 V, and bipolar ranges; isolated or non-isolated, 12 or 16-bit, thermocouple, RTD and millivolt modules. For example, our 8-channel F4-08AD analog input module offers eight channels of analog inputs and supports 4-20 mA, 0-20 mA, 0-5 V, 0-10 V, 1-5 V, +/-5 V, and +/-10 V (seven ranges) for a low price. For high-density analog, our F4-16AD-1 module supports 16 channels of current inputs at a low per-point cost.
Check our PLC System Specification Guide for a quick overview of all our analog modules.
Specialty modules to complete the system
Applications requiring the DL405's power and I/O count usually have some sort of special interfaces. See details on these modules (all documents are .pdf format):
NOTE: New option modules may not be supported by CPUs purchased prior to the modules release.
Be sure to check for the latest firmware for your PLC. You can refer to the module specification page on our Web site for this information, or find it in our free catalog.
Here is the direct link to the Firmware Upgrade section of our Web site where you can find the firmware revision histories, the latest files and tools required to download the firmware into your CPU.
