Siemens 6ES7550-1AA01-0AB0 TM Count 2x24V Technology Module (SIMATIC S7-1500, ET 200MP) CAN Electric — Industrial Automation Parts Supplier

Two independent 24 V counters in one 35 mm module

The 6ES7550-1AA01-0AB0 is the TM Count 2x24V counter module of the SIMATIC S7-1500 and ET 200MP technology module range. Each of its two channels connects a 24 V incremental encoder with A/B tracks (90° phase offset, with or without zero track N) or a pulse encoder — pulse with direction, or one pulse signal per count direction — and counts on a 32-bit counter with a parameterizable counting range.

Per-channel inputs, outputs and comparators

Each channel brings three parameterizable digital inputs for gate start/stop, capture, synchronization, probe or a freely usable function, and two transistor digital outputs switched by the channel comparators (two comparators per channel) or used as freely usable outputs. The module supports continuous counting, event-controlled stop, hardware and software gates, synchronization via digital input, and frequency, cycle-duration and velocity measurement with 100 ppm accuracy.

Technology object engineering

The module is operated with the High_Speed_Counter technology object in STEP 7 (TIA Portal), supports isochronous mode, diagnostic and hardware interrupts, and carries I&M0 to I&M3 identification data. Firmware V2.0 can be updated in the field.

Fast 24 V counting without a separate counter module

Two independent counters up to 800 kHz with quadruple evaluation keep position and speed acquisition inside the S7-1500 station, avoiding an external high-speed counter in the cabinet.

Comparators drive the outputs directly

Two comparators per channel switch the module’s own digital outputs when a count value is reached, so threshold signals react at module level rather than waiting for a program cycle.

Flexible encoder and sensor wiring

Source, sink and push-pull 24 V encoders connect directly; the common short-circuit-proof 24 V encoder supply feeds both channels, and the parameterizable input filter suppresses interference from long sensor cables.

Diagnostics and interrupts at channel level

Supply-voltage, wire-break, short-circuit and A/B transition-error monitoring with parameterizable diagnostic and hardware interrupts bring encoder faults straight into the controller program.

For RS422 / TTL incremental or SSI absolute encoder position acquisition, ask about the TM PosInput 2; for time-stamped digital I/O, PWM and oversampling, ask about the TM Timer DIDQ range.

Speed and position acquisition on 24 V encoders

Conveyor speed, shaft revolutions, flow meters and packaging-machine position feedback connect to the two channels in machine builders’ plants and retrofits running on S7-1500 or ET 200MP.

Threshold switching and measurement tasks

Comparator-driven outputs, capture inputs, frequency and cycle-duration measurement suit sorting stations, rotary tables and feed axes that need fast reaction at the module level — the same controller behind the HMI hardware listed in the Related Siemens HMI Products block below.

Condition stated in writing

We are an independent channel trader, not Siemens and not a factory-authorized distributor. Every unit supplied is genuine new, and that condition is written on every quote.

Stock you can plan a project around

We trade a broad Siemens SIMATIC S7-1500 and ET 200MP inventory; the Related Siemens list on this page shows live USD list prices with EXW Hong Kong terms, and each quote states the exact quantity available.

Export handled on one thread

Cross-border requests are routine: a single thread covers quote, compliance note and dispatch, so buyers in India, Egypt, the Netherlands, Thailand, Malaysia, the Middle East and South America deal with one team.

The TM Count 2x24V mounts on the S7-1500 mounting rail in the standard 35 mm format and works in any S7-1500 CPU station or ET 200MP interface-module station, configured in STEP 7 (TIA Portal) with the High_Speed_Counter technology object or via GSD file. The 40-pole front connector — screw-type 6ES7592-1AM00-0XB0 or push-in 6ES7592-1BM00-0XB0 — is ordered separately from the module.
