Yokogawa Electric Corporatio Models FH1A FH1V Isolator

n General The FH1A/FH1V is a compact, front terminal connection type isolator that converts DC current or DC voltage signals into isolated DC current or DC voltage signals.

n Ordering Information Specify the following when ordering. 

• Model and suffix codes: e.g. FH1V-A6*C n Input/Output Specifications Input signal: DC current or DC voltage signal Input resistance: See the table on next page. Maximum allowable input: Voltage input: ±30 V DC or less Current input: Any level that satisfies the following condition. (Input current)2 x Input resistance ≤ 0.5 W Output signal: DC current or DC voltage signal
