Schneider Electric TSX3721101 Modicon TSX Micro Modular Base Controller
The Schneider Electric TSX3721101 is a modular base controller within the Modicon TSX Micro 37 21/22 PLC automation platform. Powered by a 24 V DC supply, it provides a compact control architecture for industrial machine automation. The controller features three expansion slots, an integrated real-time clock, TER/AUX serial communication supporting Uni-Telway and Modbus RTU protocols at 19.2 kbit/s, and expandable RAM/Flash memory via PCMCIA cards.

Processing Performance and Memory Capacity
The base controller executes boolean logic instructions in 0.13 us without a PCMCIA memory card (0.19 us with a PCMCIA card) and floating-point operations in 4.5 us. System task management supports 1 master task, 1 fast task, and up to 16 event-driven tasks for deterministic control routines.
Verification: Ensure application program structures stay within internal RAM/Flash memory constraints unless a dedicated PCMCIA expansion card is inserted.
Onboard memory resources include 20 Kwords of internal RAM data, 15 Kwords of Flash memory, 128 constant words (%KWi), 1,024 internal memory words (%MWi), and 256 internal bit markers (%Mi). Installing a PCMCIA expansion card increases total program and data capacity up to 128 Kwords.
Powering and Serial Communication Interface
The unit operates on an external 24 V DC power source spanning an operating window of 19.2 to 30 V DC, with voltage dip immunity protecting against power interruptions under 10 ms. The internal power converter delivers up to 16 W of useful secondary power to installed expansion modules.
Verification: Confirm that total current draw from modules populated across the 3 slots does not exceed the 16 W secondary power budget.
Serial connectivity is available via TER and AUX mini-DIN ports, supporting Uni-Telway and Modbus RTU protocols at transmission speeds up to 19.2 kbit/s. The enclosure measures 341.4 mm wide, 151 mm high, and 152 mm deep with an overall weight of 1.72 kg for panel or rack mounting inside control enclosures.
Frequently Asked Questions
Q: What power supply parameters are required for the TSX3721101 base controller? A: It requires a nominal 24 V DC external supply operating within a tolerance range of 19.2 to 30 V DC.
Q: How is memory expanded on the TSX3721101 module? A: Program and data capacity can be expanded up to 128 Kwords by inserting a compatible PCMCIA memory card.
