IMPORTANT ORDERING INFORMATION

 

Programming requires a computer with internet connection and basic computer skills. Refer to the Instruction Manual below for programming information.

 

The USKI-5 is supplied without output relays which must be installed before the unit can be made operational. Two relay types, with different voltage and current ratings, are available through this website as indicated below. Order the types and number of relays appropriate for the desired application. The USKI-5 has provisions for up to five output relays which can be of mixed types.

 

In most applications, the lower cost high voltage, low current (OMRON G3VM-401BY, 400 V, 120 mA) relay will be more than satisfactory. They are also suitable for many higher voltage applications often found with tube type equipment.

 

When higher current switching is required on specific output channels, use the high current relay option (OMRON G3VM-61BR, 60 V, 2.5 A).

 

The USKI-5 will operate with most common 6-pin DIP MOS type relays available from various manufacturers having the same pinout as the examples listed above.
