Noncontact current detector

DA30 is a noncontact current detector that locates current flow even where voltage detectors cannot work. The unit detects ac current from 200 mA to 1000 A through shielded wires, conduit, and metal circuit breaker junction boxes. Sensitivity adjustments help to locate wires and conduits through walls. The detector provides audible and visual indication when current-carrying conductors are located.

Ethernet interface

The 1761-NET-ENI Series B module allows any computer on the connected Ethernet network to access controllers, allowing users to link without running additional network drops. This allows production data, alarm messages, or other status information to be sent to any computer, cellular phone, or pager capable of receiving email messages. The module uses existing cable, hubs, switches, and routers. The interface supports up to six connections. An optional module offers a web-enabled Ethernet interface.

Signal conditioner

Waveanalog OLP is an output loop-powered signal conditioner for use in converting and isolating control signals while deriving the power to operate from the output 4—20-mA current loop. This feature simplifies most applications by eliminating the need for a power supply and associated wiring from remote locations. The signal conditioner uses pluggable connectors that allow easy, quick installation and maintenance. Its slim design allows higher density in panel construction. The signal conditioner has DIP-switch selectable inputs of 4—20 mA, 0—20 mA, 0—5 Vdc, or 0—10 Vdc.
