Do you need a Single Proportional integral Derivative(PID), Programmable Logic Controller (PLC)?
PIDs are made up of an analog input, a controller to and output
Requests for Quote (RFQ) can be sent to Sales@layer1holdings.com State your user requirements and let Layer1Holdings quote a solution via any of the following:
Watlow and Eurotherm
Are best in Class for a Local PID Control Loops their: PM Plus can have:
Dedicated sensor to Limits (Over temp can disconnect heater Contactors)
4-20mA or 0-10V Output to SSR, Valves, Re-transmits
PID to Solid State Relays better for high Frequency control switching for Electrical Heat Controls
Do you have 4 or less Proportional Integral Derivative loops controlled at a time?
The Watlow F4T should be a top Consideration, Ethernet Connections make the F4T a great Connector for Process Sensors, Switches, Controls, Recipes, and Data Logging to Email Notifications this F4T is powerful
0.F4T
The F4T has 6 Input/Output Card Slots
0.F4T.1 FMHA-RAAA-AAAA (4 U_AI)
4 universal analog input, Select 0-10V, 4-20mA, or Thermocouple Type
Often used for Sensor Inputs
Wire selection and wire color representation changes upon User Requirements which should be defined down to the failure mode effect analysis
0.F4T.2 FMHA-CAAA-AAAA (6 U_DIO)
6 digital input or output (Grounding Switches), locally 0-5V, or external Power Supply allows for 24V
Contact Relay coils (Contactors) and Solid State Relays are set by digital switches
0.F4T.3 FMHA-FAAA-AAAA (3 U_AO)
Select 0-10V, 4-20mA analog output for Proportional Integral Derivative Controls
0.F4T.4 FMLA-LCJA-AAAA (Limit Card)
The Limit Card is a very Powerful Additional Level for Safety
Dedicate a sensor to observer for a safe state, define the limits of that safe state, and dedicate a relay for this output often to disconnect power to a device and fail to an unpowered safe state
Limit Controls are a best Practice for preventing Over-temperature Conditions for Failed Solid State Relays by disconnecting the Contactors
0.F4T.5
0.F4T.6
PID 1 Zone Controls
Watlow PM Plus with Integrated Limit Control shows a Temperature Indicator (TI) operating a Temperature Control (TC) to a Temperature Control Element (TCE) and a integrated limit using a Temperature Limit Indicator (TLI) to a Temperature Limit Control (TLC) if you would like examples of naming conventions see Layer1holdings.com/PIDs for Piping and Instrumentation naming conventions

If you like the Watlow Products, Entherm is a great Resource
