Siemens 6ES7552-1AA01-0AB0 TM Timer DIDQ 24x24V Technology Module (SIMATIC S7-1500, ET 200MP) CAN Electric — Industrial Automation Parts Supplier

Time-stamped digital I/O for fast process events

The 6ES7552-1AA01-0AB0 is the TM Timer DIDQ 24x24V technology module of the SIMATIC S7-1500 and ET 200MP range. Its configurable mix of digital inputs and outputs — up to 8 DI and 16 DQ, up to 24 channels with time stamp — records input events and triggers output events at hardware timing accuracy, independent of the program cycle. The “24” in the designation refers to the maximum 24 timestamped channels; the 24V refers to the 24 V DC signal level.

Counting, PWM, oversampling and hardware enables

Up to four counters (including counters for asymmetrical incremental encoders) run at max. 200 kHz with quadruple evaluation; up to sixteen outputs deliver PWM signals; inputs and outputs support oversampling; and hardware enables for digital inputs and outputs can be wired per channel. Two load voltages — 1L+ for the inputs and encoder supply, 2L+ for the outputs — each rated 24 V DC, keep the input and output power groups separate.

Isochronous mode and firmware update

The module operates in isochronous mode with a minimum bus cycle of 250 µs and max. 1 µs jitter, supports parameterizable replacement values, diagnostic alarms and I&M0 to I&M3 data, and carries firmware V2.0 that can be updated in the field.

Data per the official Siemens data sheet and TIA Portal manual collection for TM Timer DIDQ 24x24V (6ES7552-1AA01-0AB0); confirm the current Siemens data sheet before ordering large quantities.

Hardware time stamping without cycle dependency

Up to 24 channels record or drive events with hardware timing, so the module keeps its timing accuracy even when the CPU cycle lengthens — the standard solution for fast machine sequences that a regular digital module cannot resolve.

PWM, oversampling and counters in one module

Sixteen PWM outputs, oversampled inputs and outputs, and up to four counters at 200 kHz cover valve control, proportional output control and fast signal acquisition without adding separate function modules.

Separate input and output power groups

The 1L+ and 2L+ load voltages split the supply between inputs/encoder supply and outputs, so output switching transients do not disturb the sensor side of the station.

High-speed outputs for short pulses

High Speed outputs switch 0.1 A with microsecond delay, alongside standard 0.5 A outputs for general-purpose switching, all short-circuit and overload protected.

Fast sequence control in machines

Sorting, marking, blow-forming, clamping and riveting stations — any sequence where input events must be time-stamped and outputs driven in microsecond order — run on this module in packaging, textile and general machine automation.

Proportional and PWM control

PWM outputs drive proportional valves, heaters and lamp banks; oversampled inputs capture fast probe and encoder signals for the motion program — 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 Timer DIDQ 24x24V 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) V19 with HSP or higher. The 40-pole front connector — screw-type 6ES7592-1AM00-0XB0 or push-in 6ES7592-1BM00-0XB0 — is ordered separately from the module.
