Solid-state contactor:These Bulletin 156-B solid-state modular contractors are made by Rockwell Automation. Their primary function is to be complementary devices for the Bulletin 700 line of solid state relays, a series that provides a vast array of solutions to difficult situations. No moving parts or contacts are used in these contractors, which helps minimize the need for costly maintenance, downtime, or part replacement.
Solid-state contactor:The SAL Power Solid State Contactor has a 22.5mm highly compact design and can be used out-of-the-box with its heatsink for DIN rail mounting. It is ideal for resistive loads because of its zero cross structure.
