The Non-incendive field wiring concept allows interconnection of two FM Approved Non-incendive
Apparatuses with Non-incendive field wiring parameters not specifically examined in combination
as a system when:
Voc ≤ Vmax, Isc ≤ Imax, Ca ≥ Ci + C cable, La ≥ Li + L cable
*1: Upon condition that a shunt resistor YS021 (250 Ω ±0.1%, 3W) is attached.
Input signal Signal name Vmax (V) Imax (mA) Ci (uF) Li (mH) Remark
Analog Input (X1 to X2) Voltage input 30 0.034 0.001 0
