HoneyWell M7284 1004 Servo motor control dampers and valves 100% orignal

It took 3 calls to find someone willing to research this. Double click on above image to view full picture. Product Data Sheet Coming Soon. Ive placed some calls to our honeywell people, but I cant seem to find anyone at honeywell that actually knows. Shipping and Returns All honeywwell are shipped same-day if the order is received by 1: The motors accept a current or voltage signal from an electronic controller to position a damper or valve at any point between open and closed.

I am surpised that an “industrial” control motor has mm7284 poor performace. I did it, it worked. You are encouraged to confirm that the manufacturer part number or SKU matches the product you seek.

This has helped, but not as much as a working valve would! I am going to switch the motors out. Usually Ships in 1 – 3 Weeks. But I’ve seen first hand the effect of an acuator that can not resolve sufficient positions to control a gas valve. This class of actuator can be had with Modbus, as can Rotork. I suspect the nmber of repositions steps doesn’t matter a heck of lot when the motor drives a damper in an air handler.


So it follows that your motor doesn’t have the adjustment. Email to a Friend. I was never able to clarify why the apparent fewer reposition steps. It would seem that if the motor only runs when the input voltage is applied through the control circuit, the motor could run 0.

I have seen that with pneumatic actuators. Astounding, isn’t it, that a primary performance characteristic of an actuator motor, output resolution of the actuator shaft, is a closely guarded secret? All models have dual shafts slotted and tapped on both ends.

The Honeywell text, as usual, is not clear, but the fact that the adjustment setting affects movements in the “opposite direction from the most recent change” seems to be what is happening with regard to your applied changes. Hey all, ive noticed some odd behavior of a honeywell modutrol motor actuating a port valve. All models have auxiliary switch cams. There is some interplay between a deadband adjustment in the motor and its resolution, but I can’t recall the details.

Honeywell has a higher torque motor, the Herculine series, in a different class. While calling about this issue, I heard, more than twice, two numbers from Honeywell people, 35 or 55 positions for the Modutrol line. 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.

Motor and circuitry operate from 24 Vac. 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.

The Series ModutrollV Motors are non-spring return motors used to control mm7284 and valves. I’ll try my Honeywell contact on Monday to see if he can shed any light on your problem, honeyqell if he knows who can. Is it only the Q model that does this? So bear in mind there’s still some question on that value. Being scanned indicates that maybe it was a draft, most probably is no longer current and is obsolete? Isnt user generated content great! Have you seen our Winter Catalog or Special?
