The Schneider Modicon TM3XFHSC202G is the high-speed counting module for the TM3 I/O expansion system, handling counts up to 200 kHz on its 10 sink/source inputs with automatic reset.
Counting and Event Capabilities
Two main expert counting functions support frequency meter or period meter modes, plus up to 8 simple counting channels. Event management triggers thresholds with response under 10 µs, and latch inputs accept fast pulses at the full 200 kHz rate. The 8 transistor outputs are source-logic, each rated 300 mA on Q0…Q7, with overload and short-circuit protection. Output voltage is 24 V DC, limited to 30 V DC maximum. Power draw is 100 mA from 5 V DC backplane and 50 mA from 24 V DC external supply. Supply voltage tolerance is -15% to +20% of 24 V DC.
Mounting and Environmental Compliance
The TM3XFHSC202G snaps onto TH35-7.5 or TH35-15 DIN rail (IEC 60715) or mounts on a plate/panel with the fixing kit. With the protective cover fitted, IP20 is maintained. Rated for pollution degree 2 environments. Storage temperature spans -40…85 °C; operating altitude is 0…2000 m, storage altitude to 3000 m. Vibration and shock resistance follow EN/IEC 61131-2:2007. Listed under UL 508, CSA C22.2 No 142, CSA C22.2 No 213, ANSI/ISA 12-12-01, and EN/IEC 61131-2:2007. Electromagnetic emissions meet EN/IEC 55011 Class A for conducted and radiated ranges.
