5.12 8-CH, Medium-Speed PWM Output Module

(MX120-PWM-M08) Specifications

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 interval setting range: 1 ms to 30.000 s (can be set in

units of 1 ms)

10 ms interval setting range: 10 ms to 300.00 s (can be set in

units of 10 ms)

Output types:

Pulse width:

Update timing:

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

Pulse interval accuracy: ±100ppm of Setting
External power supply: 4 to 28 V
Insulation resistance: Between output terminals and earth terminal: 20 MΩ or more (500

VDC)

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

Set at 0 to 100.000% (0.001% resolution)

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

For 1 ms interval setting range, ±0.017% or ±2 µs whichever is
longer

For 10 ms interval setting range, ±0.0035% or ±2 µs whichever is
longer

When the load resistance is greater than 100 Ω, the output duty
can shift.

Output format:

External power supply sourcing

ON resistance:

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

Output capacity:

1 A/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)

After turning OFF external power supplies, check the load, then start up the external power

supply again.

*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:

Approx. 0.5 kg.
