Overview
The 140DAO84210C is a Modicon Quantum AC discrete output module delivering 16 isolated outputs rated 4 A rms per output in the 85...132 V AC range and 3 A rms per output at 170...253 V AC, with a dv/dt of 400 V/ms. It occupies one output word of addressing and includes internal protection via a 5 A fuse and RC filter, plus conformal coating (Humiseal 1A33) for harsh environments.
Compared to the 140DAO84000C (16 groups of 1 channel, 1 mA rms off-state leakage at 24 Vrms), the 140DAO84210C handles higher per-output current — 4 A rms per output at 85...132 V vs the 140DAO84000C's lower current — and uses a 4-channel group architecture rather than fully isolated groups. Versus the 140DDO35300C (32-point DC output), the 140DAO84210C is built for AC loads with a higher absolute maximum output of 300 Vrms 10 s AC and 400 Vrms 1 cycle AC.
