B&R is further miniaturizing the 'X20' series with two new modules: While the X20DO8323 offers eight push/pull outputs in the X20 form factor, the X20DO6639 is a 6-fold relay module for 30 V(DC) or 230 V(AC). The digital outputs of the DO8323 are electrically isolated and can be wired as either high-side, low-side or push/pull variants. This allows the module to control up to four DC motors as a full bridge with a rated voltage of 12 to 24 V(DC) and a rated current of up to 0.5 A. When operated as a half bridge, it can control up to eight motors. The DO6639 has six separate relays with normally open contacts, which can be loaded with 2 A each at 30 V(DC) and 230 V(AC).
