Siemens 6ES7522-5EH00-0AB0 DQ 16×24…48VUC/125VDC/0.5A ST Digital Output Module (SIMATIC S7-1500, ET 200MP) CAN Electric — Industrial Automation Parts Supplier

The wide-range output of the SM 522 family

The 6ES7522-5EH00-0AB0 is the DQ 16×24…48VUC/125VDC/0.5A ST digital output module of the SIMATIC S7-1500 automation system and the ET 200MP distributed I/O system. Unlike a standard 24 V DC output, it switches a wide range of loads: 24 V and 48 V DC, 24 V and 48 V UC (50…60 Hz) and up to 125 V DC, sinking or sourcing, 0.5 A per channel.

ST — basic version with substitute values

“ST” stands for standard: the module carries configurable substitute values per channel and the usual channel status LEDs, but it has no per-channel short-circuit, wire-break or supply diagnostics and no diagnostic alarm. The outputs must be protected by an external fuse (recommendation: Siemens 2 A fuse 3NW6002-4 in holder 3NW7014-4).

Fully isolated channels

Each of the 16 channels is isolated in its own group, so different load potentials can be mixed across the module; the permissible potential difference between circuits is 125 V DC / 48 V AC. The front connector is ordered separately, and the potential jumpers included with the connector must not be inserted.

Data per the official Siemens Equipment Manual DQ 16×24…48VUC/125VDC/0.5A ST (6ES7522-5EH00-0AB0) and the Siemens Industry Mall data sheet; confirm the current Siemens data sheet before ordering large quantities.

One module for several load voltages

The same 16 channels switch 24 V DC, 48 V DC, 24/48 V UC and 125 V DC loads, so mixed-voltage machines do not need a dedicated output module for each potential.

Sinking and sourcing on every channel

Each output works as a high-side (sourcing) or low-side (sinking) switch, matching NPN- or PNP-style actuator wiring and legacy load circuits without an external relay interposer.

Per-channel isolation for mixed potentials

Groups of 1 isolate every channel, with a 125 V DC / 48 V AC permissible potential difference between circuits — suitable for independent load loops that must not share a common return.

Defined state on CPU STOP

Configurable substitute values per channel define the output state when the CPU stops or the connection drops; module-internal shared output (MSO) supports PROFINET shared-device configurations.

For plain 24 V DC actuators with per-channel diagnostics, the DQ 16x24VDC/0.5A HF listed above is the matching high-feature module.

Mixed-voltage control circuits

Machines that combine 24 V DC pilot loads with 48 V UC and 125 V DC actuators — braking contactors, older DC solenoid valves, large indicator lamps and legacy relay circuits — where a standard 24 V output could not reach the load potential directly.

Retrofits and mixed-generations panels

Refits of older equipment where the new S7-1500 station inherits 125 V DC or UC field wiring, and custom panels with independent load loops kept apart by per-channel isolation — the same machines that display on the HMI hardware 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 DQ 16×24…48VUC/125VDC/0.5A ST mounts in any S7-1500 CPU station or ET 200MP interface-module station and is configured in STEP 7 (TIA Portal) or via GSD file. The 40-pin front connector is not included; order the screw-type or push-in version separately, do not install the potential jumpers, and fit the recommended external 2 A fuse per load group. Observe the current derating in the Siemens manual for your voltage, ambient temperature and mounting position.
