1.2 Precautions

1-7

• Connect an AC power supply (100/200 VAC) or a DC power supply (12/24 VDC) to

the Power Supply for driving loads of the Relay Contact Output Module.

Do not connect both an AC power supply and a DC power supply to one Module
at the same time. If unsuitable power supplies are connected, in overheating or
fire may result.

• Although a 0.6-A load can be connected to each output point for the AC 16-point

Output Module, the total load must be 2.4A or less for each common. Keep the
maximum load at 2.4A for each common.

If this limit is exceeded, damage may occur to the output circuit.

• Although a 0.5-A load can be connected to each output point for the DC 16-point

Output Module, the total load must be 1.0 A or less for each of the four output
points. Keep the load distribution within the 1.0 A limit.

If this limit is exceeded, damage may occur to the output circuit.

• Although a 0.3-A load can be connected to each output point of the DC 32-point

Output Module, the total load must be 0.4 A or less for each of the four output
points. Keep the load distribution within the 0.4 A limit.

If this limit is exceeded, damage may occur to the output circuit.

• If using an Output Module, connect a fuse that complies with the load specifications

in series with the load.

• 100/200-VAC 8-point Output Module: Model No. JAMSC-120DAO83000

• 100/200-VAC 16-point Output Module: Model No. JAMSC-120DAO84300

• 12/24-VDC 16-point Output Module (sinking output):

Model No. JAMSC-120DDO33000

• 12/24-VDC 16-point Output Module (sourcing output):

Model No. JAMSC-120DAO34320

• 12/24-VDC 32-point Output Module (sinking output):

Model No. JAMSC-120DAO35410

• 12/24 VDC 64-point Output Module (sinking output):

Model No. JAMSC-120DAO36410

• Relay Contact 16-point Output Module: Model No. JAMSC-120DAO84300

If a fuse is not connected, a fire or damage to the device or output circuit may
occur if the load is short-circuited or the circuit overloaded.

• If connecting an inductive load in parallel with AC Input Module, connect the surge

absorber in parallel with the inductive load to prevent surge voltage.

Failure to connect a surge absorber may result in damage to the AC Input Mod-
ule.

• If connecting an inductive load to the AC Output Module, connect the surge

absorber in parallel with the inductive load to prevent surge voltage.

Failure to connect a surge absorber may result in damage to the AC Output
Module.
