Functions & Features

blank: none

• Used for 24 - 200 V AC electric actuator position control

• Controls the electric actuator to a pre-configured target

position based on contact input

/Q: Option other than the above (specify the specification)

• Position feedback via potentiometer (100 Ω - 10 kΩ

unadjusted)

SPECIFICATIONS OF OPTION: Q (multiple selections)

COATING (For the detail, refer to M-System's web site.)

/C01: Silicone coating

• Direct motor driving with built-in SSR (with zero-cross

circuit)

/C02: Polyurethane coating

• Restart control timer built-in to prevent motor overheating

due to frequent on/off switching

/C03: Rubber coating

TERMINAL SCREW MATERIAL

/S01: Stainless steel

Typical Applications

• Position damper control using sequencers without analog

output

GENERAL SPECIFICATIONS

Construction: Plug-in

Connection: M3.5 screw terminals

Screw terminal: Chromated steel (standard) or stainless

steel

(2.83)

Housing material: Flame-resistant resin (black)

Full-closed position adjustment range: 0 - 25 % (front)

Full-open position adjustment range: 75 - 100 % (front)

Preset adjustment range: 0 to 100 % corresponding to Full-

(5.35)

Deadband: 0.6 - 10.6 % (front)

mm (inch)

Timer adjustment: 1 – 30 sec. (front)

Isolation: Contact input to feedback potentiometer to

control output to power

MODEL: MEX-P-[1][2]

Lock protection timer: If the motor doesn't enter the

deadband for approx. 2 minutes, then power supply is cut;

reset is performed by power OFF or repeating full-open and

full-close actions

EXPLANATIONS OF TERMS

• SSR (Solid State Relay)

Composed only of semiconductor parts, SSR is free from arc discharge or chattering which is typical with electromagnetic

relays. It features excellent characteristics against vibration, physical impact or other environmental conditions.

• Zero-Cross Function

SSR with zero-cross function turns on when AC power voltage is near zero, creating delay of switching when input is provided in

the middle of an wave cycle, thus limiting transient switching noise voltage and rush current.

Specifications are subject to change without notice.
