[Example] When power supply voltage of 12V

When using H-TIO-B modules together with H-TIO-D modules

As the H-TIO-D module consumes an output current of 80 mA/slot and the H-TIO-B module, an

output current of 40 mA, the following current is obtained.

For H-TIO-D (3 modules): 80 mA

3 = 240 mA,

For H-TIO-B (4 modules): 40 mA

4 = 160 mA

240 mA + 160 mA = 400 mA

1000 mA: Maximum power supply capacity

The above current does not exceed the maximum power supply capacity (1000 mA). However, as one

H-TIO-D module is assumed to correspond to two function modules, up to 7 function modules can

be mounted.

When using H-DO-A-M modules together with H-TIO-B modules

As an example in which the H-DO modules need to be added for outputting the alarm independently

for each channel, when (H-DO-A-M modules: 3 modules) are added to (H-TIO-B modules: 7

modules):

Each consuming output current becomes as follows.

For H-TIO-B modules (7 modules): 40 mA

7 = 280 mA,

For H-DO-A-M modules (3 modules): 140 mA

3 = 420 mA

280 mA + 420 mA = 700 mA

1000 mA: Maximum power supply capacity

As the total current described above does not exceed the maximum power supply capacity (1000 mA),

up to 10 function modules can be mounted.
