Click here to enlarge image

Officials at Teledyne Relays in Hawthorne, Calif., are offering two plastic six-pin dual inline package solid-state relays for military, aerospace, and commercial applications. The relays, called the ZD20CF and the ZD24CC, offer extended operating temperature range, overload protection, and screening options. The ZD20CF is a 2-amp, 60-volt DC relay, while the ZD24CC is a 500-milliamp, 80-volt DC relay. Overload protection detects a short in the circuit and trips the relay off.

Board Products

Remote solid-state power-controller board

Data Device Corp. (DDC) in Bohemia, N.Y., is offering the remote solid-state power-controller (RPC) boards that enable military ground vehicles, commercial aircraft, and military aircraft to protect wiring from overloading. These boards, which are sometimes called solid-state power-controller modules, combine several channels on one board, and use surface-mount technology to accommodate as many as 16 channels with a total current rating of 160 amps per board. The RPC board technology uses a digital signal processor to provide on-board intelligence and control enable, disable, or reset each channel independently. The RPC boards, which are designed to withstand rugged military environments such as humidity, vibration, EMI, and temperature, are conformally coated to provide moisture resistance and are EMI tolerant. The mechanical design complies with standard ground vehicle and aircraft environmental requirements. The standard operating temperature range is -40 to 85 degrees Celsius.

Devcon in Danvers, Mass., is offering Syon electrically conductive adhesive solders to form conductive paths in applications where hot soldering would be ineffective or impractical. The Syon solders are epoxy and spoxide formulations that cure with minimal air entrapment, company officials say. The Syon Tru-Bond 206A solder is a pourable liquid for bonding electrical components that hot solder could damage, or for uses where hot solder would not bond well. Tru-Bond 214 is a silver-filed non-sagging epoxy paste for ­applications where a conductive bond is necessary, but where hot solder is impractical. For more information contact Devcon online at
