2.Core Features:

The Siemens 6RY1703-0GA01 (full order number C98043-A7009-L1-6) is a "Power Interface Board" (PIB) specifically for the SIMOREG DC Master 6RA70 series. It plugs into the back of the 6RA70 chassis and amplifies six fiber-optic pulses from the CPU into 1200 V / 3 A gate trigger signals. It also performs SCR commutation absorption, current detection and amplification, temperature monitoring, and fuse status feedback.
