Module overview and lifecycle status
The Schneider Electric 140DAM59000C is a Modicon Quantum mixed discrete I/O module classified as end-of-life (EOL). It provides 16 115V AC inputs in two groups of 8 and 8 solid-state outputs in two groups of 4, with a maximum module load current of 8A. The module conforms to CSA C22.2 No 142, FM Class 1 Division 2, and UL 508 standards, making it suitable for use in hazardous locations and UL-listed industrial control panels. Input voltage limits are 85–132V AC typical (156V for 10s, 200V for 1 cycle); output voltage limits are 85–132V AC typical (156V AC for 10s, 200V AC for 1 cycle). Network frequency range is 47–63Hz.
Key electrical and protection specs
Output protection includes an internal 5A fuse per group and an RC filter per output. Fault indication is provided via blown-fuse detection and loss of field power signaling. Eight local LEDs show communication active, voltage status, output on, and fault conditions per point. The module draws 250mA from the Quantum backplane, requiring one input word and 0.5 output word of addressing. Isolation between output groups is rated at 1000Vrms for 1 minute. A conformal coating (Humiseal 1A33) protects the board against moisture and contaminants. Operating altitude is up to 5000m, and relative humidity tolerance is 95% without condensation.
Response times and switching characteristics
Response time: 4.9...0.75 ms (0→1) and 7.3...12.3 ms (1→0); output turn-off ≤0.5 ms. DV/dt is 400 V/µs; leakage 2.1 mA (input) and 2 mA (output).
