- 115VAC to 24VDC -

Bonitron’s M3402 Logic Interface is a drive option module which permits existing 115 VAC control wiring (Start, Stop, Run, Jog, etc.) to be interfaced to the Reliance GV3000 AC Drive. Additional interface options are available for other Variable Frequency Drives.

Many modern drives have input control logic that is designed for operation with sourced 24 Volt DC levels which are compatible with PLCs. Also, standard pushbuttons, toggle switches, or dry relay contacts can be used to source 24 VDC.

However, many existing systems have 115 VAC control wiring. The Bonitron Logic Interface converts these high voltage AC control signals to the 24 VDC logic signals required by the drive. The interface board provides high noise immunity and optical isolation and is UL approved.
