Specifications

Anti-windup

If the position form of the PID equation is specified, the reset action is stopped when the PID output reaches 0 or 100%. Select adjusted bias or freeze

Auto Tuning

Open loop step response method and closed loop limit cycle method.

Bumpless Transfer I

Bias and setpoint are initialized automatically when the loop is switched from manual to automatic. This provides for a bumpless transfer, which

Bumpless Transfer II

Bias is set equal to the Output when the module is switched from manual to automatic. This allows switching in and out of automatic mode without

CPU V-memory Required

32 V-memory locations per loop selected (An additional 32 V-memory locations per loop required if using Ramp/Soak)

Error Deadband

Specify an incremental value above and below the setpoint in which no change in output is made.

Error Squared

Squaring the error minimizes the effect a small error has on the Loop output, however, both Error Squared and Error Deadband control may be enabled

Gain

Specify proportional gain of 0.01 to 99.99.

Limit OUT

Specify a maximum and minimum value for the output range.

Limit SP

Specify a maximum and minimum value for allowable setpoint changes.

Loop Operation Modes

Loop can be in automatic control, manual (operator) control, or cascade control. PV alarm monitoring continues when loops are in manual mode.

Number of Loops

Selectable, 16 maximum

PID Algorithm

Position or velocity form of the PID equation. Optionally specify direct or reverse acting, square root of the error and error squared control.

Ramp/Soak

Up to 16 steps (8 ramp, 8 soak) per loop, with indication of Ramp/Soak step.

Rate

Specify the derivative time, 0.00 to 99.99 seconds.

Rate Limiting

Specify a derivative gain limiting coefficient to filter the PV used in calculating the derivative term (0 to 20).

Reset

Specify integral time of 0.1 to 99.98 in units of seconds or minutes.

Sample Rate

Specify the time interval between PV samples, 0.05 to 99.99 in units of seconds or minutes. If using all 16 loops, the smallestsample rate is limited to either 0.2 seconds or (PLC scan time x number of loops).

Square Root PV

Specify a square root of the PV for a flow control application.

Step Bias

Provides proportional bias adjustment for large setpoint changes. This may stabilize the loop faster and reduce the chance of the output going out of

Frequently asked questions

At GID Industrial (Elite.Parts' parent company), we specialize in procuring industrial parts. We know where to find the rare and obsolete equipment that our customers need in order to get back to business. There are other companies who claim to do what we do, but we're confident that our commitment to quality and value is unparalleled in our field.

Warranties differ by part and by which suppliers we use to procure it for you. Sometimes, a part will be sold as-is and without a warranty. Our specialty, single board computers, tend to receive a one-year warranty.

Elite.Parts can ship via FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. However, we can use other carriers if it will be more convenient for you.

Absolutely! We are happy to serve customers regardless of location. We work with international clients all the time, and we are familiar with shipping to destinations all across the globe.

HARD TO FIND A BETTER PROVIDER

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

Applied Materials

CONSISTENTLY DELIVERS QUALITY SOLUTIONS

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
