Introduction
The MDP series motor controls are compact, microprocessor-based units capable of being either field
or factory configured for a number of industry's motion control needs. These controls are designed
around a pulse-accumulation PI algorithm. They can be easily configured to operate as a digital speed
controller, time-based process controller, or a ratiometric follower controller in master-slave systems.
Utilizing Dart's new modular bus design techniques, the MDP series is ideal for volume OEM
applications requiring specialized inputs and outputs. Contact Dart Controls' Sales Department for
details. This flexibility makes the MDP series ideal for applications such as:
Water and Waste Treatment Systems
Conveyor Oven Controllers
Synchronized Conveyor Lines
Its durable 1/8 and 1/4 DIN aluminum housings can be easily mounted in a panel or control cabinet. New
optional pluggable terminal block allows the installer to quickly install or replace units without the hassle
of physically removing and reattaching wires. The units can be ordered with either standard European-
style terminal block or optional “pluggable” connector.
General Features
- Microprocessor-based design combines the ultimate in responsiveness and accuracy in one package
- Digital closed-loop algorithm ensures long-term accuracy of +/-1/2 RPM of set speed or equiv.
- Non-volatile memory stores adjustable parameters even when power has been removed
- Factory or field programmable via front-panel keypad
- Adjustable parameters include min, max, accel, decel, display options, alarm options, etc.
- Internal program-enable jumper selectively prevents tampering with unit’s configuration
- Universal power supply accepts line voltages inputs from 85-265VAC @ 50-60Hz without switches
or jumpers. The unit automatically adjusts as needed.
- Transient voltage protection prolongs unit's life in harsh industrial environments
- Compatible with a variety of signal input types including: Hall-Effect Pickups, Photoelectric, TTL, etc.
Note: Open collector devices must be capable of sinking 3mA.
- Self-contained power supply for external sensor, limited to 5V @ 50mA
- Programmable alarm output with Form C contacts rated to 250VAC @ 5A
- Flexible user inputs support inhibit, emergency stop, and jog functionality.
- 1/8 and 1/4 DIN durable aluminum housing for panel mounting the MD10P and MD3P, respectively.
- Large 4 digit, 1/2” LED display
- G.E. Lexan membrane and gasket (which are included) meet NEMA 4X standards when used with
NEMA 4X enclosures
- European terminal block or pluggable terminal block available
- Recognized, file #E78180 (MD10P, MD3P & MD3E)
- Wide operating ambient temperature range of -10C to 45C (14F to 113F)
- Multiple operating modes including:
•
Master, Rate Mode – Controls in rate unit such as RPM, Gallons per Second, etc.
•
Master, Time Mode – Controls in time unit such as HH:MM, MM:SS, SS:TT, or other unit
•
Follower Mode – Controls in percentage of master rate. This mode allows the MDP control to
precisely follow the actions of a master process without any long-term loss of position
