Processor Architecture and Memory Organization

The TSX3708001 uses an 8-bit processor running at 20 MHz. This processor executes boolean instructions in just 0.5 microseconds. The module stores user programs in 16 KB of battery-backed RAM memory. It keeps runtime data in 4 KB of on-board RAM. The Schneider TSX3708001 supports up to 80 timers and 80 counters. Its compact design suits small control cabinets with space limitations.

Built-in I/O and Field Connections

This Modicon TSX Micro PLC features 16 digital input channels on board. Each input accepts 24 V DC signals from sensors, switches, and pushbuttons. Twelve transistor output channels switch loads up to 0.5 amperes at 24 V DC. The outputs suit solenoids, indicator lamps, and small relays. The TSX3708001 includes 28 status LEDs for I/O point monitoring. Green LEDs show input and output states at a glance.

Programming and Communication Features

The Schneider TSX3708001 programs using PL7 Micro software for TSX platforms. A built-in RS-232 port connects directly to a PC for program download. The module supports ladder diagram and instruction list programming languages. You can monitor and force I/O points through the programming port. The TSX3708001 stores the user program in battery-backed RAM. A power-down retention time of 30 days requires a healthy battery.

Physical Dimensions and Installation Guidelines

The Schneider TSX3708001 weighs 0.400 kilograms for DIN rail or panel mounting. Its height measures 103mm, width 70mm, and depth 84mm. Install this Micro PLC on standard 35 mm DIN rail inside the cabinet. The unit consumes 18 VA of power from the AC supply. It operates reliably from 0°C to +55°C ambient temperature. Use screw terminal connections for all field I/O wiring.

Energy Storage and Battery Maintenance

The TSX3708001 uses a 200 mAh lithium battery for program and data backup. This battery preserves user logic, data registers, counters, and timers. The battery lasts approximately two years under normal conditions. Replace the battery when the low battery LED indicator lights up. Always replace the battery with the Schneider TSX3708001 powered on. The Micro PLC loses no program during battery replacement with power applied.
