*1: When SDV144-S6 or -SF is selected, you cannot choose the option code for a pressure clamp terminal block and MIL

cable connector.

*2: When this module is used in dual-redundant configuration, order an additional module with the same specification but

without option codes.

*3: When SDV144-S6 or -SF is selected, you can choose the option code for prevention pin of false insertion.

A mechanism to prevent wrong type I/O module insertion is supported with signal cable. The signal cable used with this I/O

module must have option code /SDV144.

Approx. 0.41 kg (With signal cable interface adapter)

External connection

Pressure clamp terminal

MIL cable

Dedicated signal cable (AKB331)

*1: These voltages show the case using the field power supply floating. When the field power supply is grounded, the system

(functional) ground is connected to the field ground, which is not isolated. For the higher noise immunity, floating the field

power supply is recommended.

*2: When the withstanding voltage of the field power supply between the secondary side and the ground is lower than the value

shown in the table above, these voltages are adopted as the withstanding voltage of the field power supply.

*3: Number of input channels which a user can use and external power supply are restricted in case of SDV144-SC.

Refer to “ProSafe-RS Outline of I/O Modules (for FIO)” (GS 32P06K60-01EN).

*4: The contact rating and the external power supply of SDV144 style code S1, S2 and S3 are 24 V DC ± 5 %.

*5: When connecting SDV144 and SED4D terminal board using the dedicated signal cable, the withstand voltage is 500 V AC

(between input signal lines and system). If MIL connector cables are used, the withstand voltage depends on their cable’s

electrical specifications

If SDV144 field wiring diagnostic functions are used, the following diagnostic elements should be installed for

individual channels in the vicinity of the field equipment:

• SCB100 (for defective open circuit detection while accepting off signals) (*1)

• SCB110 (for defective short-circuit detection while accepting on signals) (*2)

*1: Input signals are normally off while in normal operation.

*2: Input signals are normally on while in normal operation.
