Description
The SHD30 and SHD30-45 models are microprocessor-bad digital tachometers with hourmeter and overspeed trip point. The overspeed trip point can be connected as either a form “C”relay output or as a normally open SCR output.
In Class I, Div. 2, hazardous locations the SHD30 form “C”relay contact is restricted for u with Murphy non-incendive or intrinsically-safe instruments. In non-hazardous locations the relay contact may be ud to switch resistive loads not exceeding 0.5 A @ 30 VDC or 125 V AC.
When connected as a normally open SCR, the output is rated 0.5 A, 350 VDC continuous and can switch up to 3 A @ 350 VDC momentary. The SCR output may be ud to switch designated normally open nsor inputs.

Mounting
The SHD30 is designed for installation in panels from 0.032 to 0.125 in. (1 to 3 mm) thick. A round hole, 3-1/8 in. (79 mm) in diameter is needed for mounting. Install the unit within a weatherproof enclosure to protect it from the elements. Keep the unit away from ignition coils and coil leads; a mini-
Plea read the following information before installing . A visual inspection for any damage which may have occurred during shipping is recommended. It is your responsibility to have a qualified person install the unit, and make sure it conforms with NEC and local codes.国外logo设计网站
