This is a 4 – 20 system, and the ma value does change when I change the plc output. The motors accept a current or voltage signal from an electronic controller to position a damper or 7m284 at any point between open and closed.

While calling about this issue, I heard, more than twice, two numbers from Honeywell people, 35 or 55 positions for the Modutrol line. Ill check to see if it has a dead band.

Isnt user generated content great! The Series ModutrollV Motors are non-spring return motors used to control dampers and valves.

Images and descriptions may not accurately represent the product. I suspect the nmber of repositions steps doesn’t matter a heck of lot when the motor drives a damper in an air handler. Double click on above image to view full picture. All models have dual shafts slotted and tapped on hineywell ends.

Models available with factory installed transformer, or a field added internal transformer. JPG But it’s given its cost, a can only be justified where the torque and resolution performance is required, like ID or FD control honneywell on boilers. There seems to be some kind of deadband effecting the repsone of the valve. It is a C Terms Of Use Privacy Statement.

Is it only the Q model that does this?

Why not an actuator where you could send the requred position and get feedback on the actual position, maybe hkneywell alter the speed of travel, all via serial comms? So it follows that your motor doesn’t have the adjustment.

This has helped, but not as much as a working valve would! All models have auxiliary switch cams.

Fixed torque throughout the entire voltage range. Be the first to review this product. Ive placed some calls to our honeywell people, but I cant seem to find anyone at honeywell that actually knows. I found a guy at the Honeywell support numberwho had to do 10 minutes of research to find out how many steps of resolution any Modutrol motor would provide not exactly public information.

The ideal cotnrol position was in between motor reposition-steps. Quick-connect terminals are standard; screw terminal adapter is available. It specs the reposition resolution. You can also find answers to some common questions on our FAQ page.

I did it, it worked. Astounding, isn’t it, that a primary performance characteristic of an actuator motor, output resolution of the actuator shaft, is a closely guarded secret? There are 4 ‘enhanced’ Modutrol IV models, all of which are mA proportional honfywell, each of which has more than 55 repositions.

It sure wasnt easy getting it out of honeywell, I am glad you did. The oven lined out nicely with a slower honeyqell and the motor did not goneywell. And since the major market for this category of actuator is HVAC, well, you take what you get. Maybe such a device exists that I’m unaware of – anybody come across one?

BC’s support response was to replace the motor with a slower motor. Models available with 4 to 20 rnA input signal. While investigating a “poor control” complaint, I discovered that Barber Colman motors this was 20 years ago used the same die cast housing, same electric motor, same slidewire, but just changed the gear train.

I tend to go for Kromschroder GT motors, GT31 usually and GT50 for bigger valves, they do a good range of different supply voltages and travel times and the end of stroke and signalling limit switches are easy to adjust. Email to a Friend.
