 | High Speed Counting, Pulse Profile, & Motion Control
The H4-CTRIO High Speed Counter module is used in motion control (pulse-profile & speed), and high speed (100KHz) counting and positioning applications. Use the H4-CTRIO module with the D4-450 CPUs only. The module plugs into any I/O slot of any DirectLOGIC 405 local base and is not supported in expansion bases. The H4-CTRIO module is supported in the H4-EBC.
The D4-HSC high-speed counter provides high-speed up or down counting capability. It provides the user with count data and output signals such as clockwise, counter-clockwise, decelerate, and equal. The module functions asynchronously with the DL405 CPU, allowing fast response and control. |

 | Stand-Alone Temperature Control CoProcessor
The F4-4LTC combines the features of four Single Loop Temperature Controllers into one inexpensive module. The module has four asynchronous, configurable PID loops, with built-in temperature inputs and control outputs so that precision temperature control is maintained, even while the PLC is in program mode. This module can control temperatures up to ±3276.7°C/°F and accepts either thermocouple or RTD inputs.
Transformer (F4-CT)
The F4-CT detects the presence of current flow and is very useful in detecting heater burnout conditions. One F4-CT is included with the 4-loop Temperature Controller Module. |

| Add Multiple Analogue PID Loops
The F4-16PID is a Proportional Integral Derivative (PID) CoProcessor designed to execute up to 16 PID loops independent of the DL405 CPU. Using the high-speed Intelligent bus interface, the F4-16PID reads the process variable and writes the PID output directly into V-memory of the DL405 CPU.

 | High Speed Interrupt Input Module
The D4-INT is an 8-point interrupt module. This module is intended for applications that have a high-priority event that requires special operations to be performed. When this high priority event occurs, the interrupt module senses a DC level input signal. The module automatically informs the CPU to interrupt its present operation. The CPU immediately suspends its routine scan cycle and jumps to a subroutine identified with that particular interrupt input signal point. The CPU then executes the logic in the subroutine (subroutines can even use immediate I/O instructions to immediately read and write I/O points if a time-critical update is necessary). When the subroutine is complete, the CPU automatically resumes its routine scan cycle starting at the exact location where it was interrupted. The CPU continues the routine scan until another interrupt signal is sensed.

 | DL405 BASIC Programmable CoProcessors
The FACTS CoProcessor Module interfaces the DirectLOGIC 405 family of programmable controllers with bar code readers, operator interface terminals, instrumentation equipment, computers, and other serial devices. Three ports offer a range of communication interfaces and baud rates. |

| Flow measurement CoProcessor
The F4-8MPI is an eight-channel Magnetic Pulse Input CoProcessor Module. It is designed to take input pulses from Hall effect type magnetic pick-ups, (typically found on turbine meters, tachometers and signal generators), and perform calculations. Up to eight differential inputs from magnetic pickups are wired directly to the terminal block on the front of the module. |
