Efficient heat dissipation means not wasting space for cooling. Phoenix Contact's solid-state Electronic Load Relays (ELRs) feature a large integrated heat sink at the base to deal with heat from switching high-power loads (up to 500V ac at 9A per phase). The devices can be used for motor control with inductive loads up to 4 kW or with resistive loads up to 7.5 kW without contact wear. A 24V dc signal activates the ELR switching circuit. The four types of ELRs can be wired with individual discrete terminations or ribbon-cable connectors used in the company's PLC System Cabling and INTERBUS(TM) systems. Other applications include injection molding, materials handling, and high-speed packaging. Phoenix Contact: Product Code 4311
Sensor deployment in automated factories should be done slowly and conservatively, otherwise engineers may face the loss of hundreds of thousands or even millions of dollars, an Internet of Things expert will tell attendees at the upcoming Design & Manufacturing Show in Minneapolis.
