About Appoldt
Appoldt GmbH from Düsseldorf is an engineering office for industrial electronics and interface technology with its own manufacturing and distribution. The product range includes relay couplers, solid-state relays (SSR) in DC/DC, DC/AC and AC/AC versions including heat sinks, building automation relays, safety and brake-switching relays, time and impulse relays as well as monitoring modules such as current monitors, motor protection relays, power supplies, DC/DC converters, current transformers and redundancy modules. In addition, the company offers handover modules and bus components for PLC interfaces (including S7-300), pre-assembled S7 and Mitsubishi PLC system cables as well as special modules, machine controls and PCB-based controls. Alongside module manufacturing, Appoldt develops customer-specific solutions for interface technology and optoelectronics. The company is also an authorized distributor of CRYDOM solid-state relays. The products are designed for use in building automation, control cabinet construction and machine controls and are documented in a German/English product catalog.
