61 Auto Switch Internal Circuit Diagnostic Output Operation Dimensions D-H7NF (With indicator light) Auto switch part no. Wiring type Output type Diagnostic output type Applicable load Power supply voltage Current consumption Load voltage Load current Internal voltage drop Leakage current Indicator light Standard D-H7NF 4-wire NPN Normal operation IC circuit, Relay, PLC 5, 12, 24 VDC (4.5 to 28 VDC) 10 mA or less 28 VDC or less 50 mA or less at the total amount of normal output and diagnostic output 1.5 V or less (0.8 V or less at 5 mA) 100 μA or less at 24 VDC Conforming to CE Operating position .......... Red LED illuminates. Optimum operating position .......... Green LED illuminates. Since the output signal can be detected in an unsteady detecting area, the difference of detecting position can be confirmed by the side of PLC (Programmable Logic Controller).  The optimum operating position can be determined by the color of the light. (Red → Green ← Red) The diagnostic signal is output within unsteady detecting area (where indicator light is Red), and the diagnostic output becomes OFF when the detecting position remains within the optimum operating position (where indicator is Green). When the detecting position is not adjusted, the diagnostic output becomes ON. OUT (Normal output) Black DC (+) Brown DC (.)
