The solid-state relay PI 9260 was developed for switching resistive threephase A.C. current loads, and therefore serves as a replacement for an electronic contactor. Both 2-phase and 3-phase controlled versions are available. The DCB technology (direct copper bonding) ensures very good thermal transmission, so that high load currents are possible. The solidstate relay can be mounted on a variety of cooling surfaces. The device is also available as a ready-to-use version with a pre-dimensioned heat sink. This can simply be snapped onto a wide DIN rail. An LED display signals the status of the control input. The voltage range of 4 to 32 V allows for operation on digital controllers (PLC) or simple temperature regulators.
