4.11 8-CH, Medium-Speed PWM Output Module

(MX120-PWM-M08) Specificaions

Style number:

Number of outputs:

Update interval:

100 ms minimum (not synchronized to the measurement interval)

Output interval:

1 ms to 300 s (can be set channel by channel)

However,

1 ms intvl settg rng: 1 ms-30.000 s can be set in units of 1 ms

10 ms intvl settg rng: 10 ms-30.000 s can be set in units of 10 ms

Output types:

Pulse width

Update timing:

After receiving change command, duty is changed from falling
edge of the next interval

Pulse interval accuracy:

±100 ppm of setting

External power supply:

4 to 28V

Insulation resistance: 20 MΩ or more (500 VDC) between output terminal and earth

Across output terminals: non-isolated

Withstand voltage:

2300 VAC (50/60 Hz) for one minute between the output terminal
and earth

Across output terminals: non-isolated

Duty resolution:

1 ms interval setting range: 12000

10 ms interval setting range: 60000

However, the PC software sets 0 to 100.000% (0.001% resolution)

MX main unit/API, sets 0-100% with 0 to 00000 count.

Duty accuracy (load resistance at 100Ω or less):

1 ms freq. setting rng: the longer of ±0.017% or ±2 µs

10 ms freq. setting rng: the longer of ±0.0035% or ±2 µs

If the load impedance is greater than 100 Ω, the output duty may
vary.

Output format:

External power supply sourcing

ON resistance:

2 Ω or less (however, when output current is 200 mA or more.)

Output capacity:

1A/ch max, however, 4 A or less total for all modules

*1, *2

*1 A 1A current limit circuit is built in to the output circuit. Once the current limit circuit is ON,

the circuit continues to operate unless the external power supply is turned OFF (maintains
the output off status). Once the external power supply has been turned OFF, restart the
external power supply after checking the load status.

*2 This module has a built-in fuse. The built-in fuse protects against fires or abnormal

emissions of heat due to load short-circuiting or other abnormalities.

Power consumption: Approx. 2.5 W (not including power consumption of external

power supply)

Terminal type:

Clamp, attached and removed in units of 4 channels

Applicable wire size: 0.08 to 2.5 mm

(AWG28 to 12)

External dimensions: Approx. 57 (W) × 131 (H) × 151 (D) mm (including the terminal

cover)

Weight:

Approximately 0.5 kg
