Model 645T two-wire transmitters from this company feature two independent I/O channels in a single package. The product is said to receive dc voltage input signals, provide isolation, and create output proportional to 4 to 20 mA dc current signals. The product also is said to provide two independent high-voltage isolation circuits, so that power loss on one channel does not affect the other.

PGA ZIF test sockets from this company now include a 9 x 9 grid size version, allowing just one socket to handle a full range of device sizes, footprints, and pin counts. A metal cam in each socket activates the product's normally closed contacts, eliminating a dependency on plastic to sustain contact force. A stainless steel handle can be provided on either the right or left side, and the product plugs into standard PGA sockets.

IR2170 is an over-current sensing IC for ac or brushless dc motor drive applications up to 230V ac input. The product is designed to sense motor current directly through an external sense resistor and report an error if the current exceeds a preset threshold in either negative or positive polarities. Applications include light industrial ac and brushless dc motor drives, and appliances such as washing machines and air conditioners.
