Pilz / PSS controllers, PIT operator devices and PMC drives

The F versus S letter decides whether a module is part of your safety function. Plus what PITmode needs that is not in the box.

This page covers the rest of the Pilz range: PSS and PSSuniversal safety controllers, PIT operator and access devices, PMD monitoring relays, PMC servo drives and PMI terminals.

PSSuniversal: F is failsafe, S is standard

The most important thing here, and it repeats the trap that runs through the PNOZmulti range.

F and S modules look alike, fit the same base and appear to work identically. Only the F modules are part of the safety function.

The same letter convention runs through the PSS u2 range: EF modules are failsafe, ES modules are standard.

When you send us a module number, we will flag which category it is in. If you are replacing a failed module, check the original rather than matching on I/O count.

PSSuniversal modules

Head modules

Electronic modules

Base modules

Electronic modules sit on base modules. Both are separate order lines, the same pattern as FLEX 5000 and Compact 5000 on the Allen-Bradley side.

PSS u2

PSS67, IP67 on-machine

Legacy PSS

These are long discontinued and secondary market only. We do get enquiries for them.

PITmode needs a PITreader

An ordering catch worth knowing before you quote a job.

The PITmode safe evaluation unit handles operating mode selection: four operating modes OM1 to OM4 plus a special mode OM5, with a Key ID interface that reads the transponder key.

Pilz lists required accessories, not optional ones:

You need one of the two base units and the key adapter. A PITmode evaluation unit on its own cannot read a key and cannot select a mode.

Optional accessories are the connector set, order number 402306, and the PIT oe 4S, order number 402311.

PITmode and PITreader models

Keys are ordered per operating mode. KEY MODE 01 through 04 are separate parts. If a machine has four modes and someone has lost the key for mode 3, that is a specific part number.

PITestop E-STOP devices

The difference between those two is the housing. If you are mounting into an existing panel cutout you want 400432; if you need a standalone box on a machine frame you want 400447.

PIT es pushbuttons and accessories

The installation wrench is a real part. If you are fitting several E-STOPs it is worth having rather than improvising.

PSENmlock guard locking, full model list

Expanding on the PSEN page, since these numbers are easy to confuse.

The b and s letters are the wiring version. b is basic for individual wiring; s is for series connection. If your gates are daisy-chained you need the s version.

Escape release and auxiliary release are different things. An escape release lets someone trapped inside open the guard from within. An auxiliary release allows manual release from outside, typically with a tool. Check which your machine has before ordering.

PSENslock models

Note again the switch and actuator distinction in the naming. The 0.5 and 1.0 refer to magnetic holding force in kilonewtons, so PSEN sl-0.5 is 500 N and PSEN sl-1.0 is 1000 N.

PMC servo drives and motors

The PMCtendo numbering carries the voltage. A DD5.03/230V and a DD5.03/480V are the same frame at different supply voltages. Read the whole designation.

PMI operator terminals

Monitoring relays

Important: safety replacements

Safety components are certified as part of a machine's safety function, with a rated Category or Performance Level.

A like-for-like replacement of the same order number preserves that assessment. A substitution may not. Substituting a standard-rated module for a failsafe one, a basic guard lock for a series-connection version, or a unit without escape release where one is fitted, can change the achieved Performance Level or leave someone unable to exit a guarded area.

We will supply the exact order number you specify. If you ask us to suggest an alternative we will tell you what we think is equivalent and what differs, but the decision on whether a substitution is valid for your safety function belongs to whoever is responsible for the machine's safety assessment. We are a parts supplier, not your safety engineer.

What we can supply

Current production. PSSuniversal and PSS u2 modules, PSS67, PIT operator and access devices, PITreader, PSENmlock and PSENslock, PMD monitors, PMC drives. Quoted with a delivered lead time.

Discontinued. Legacy PSS controllers, older PMI terminals and earlier PMC drives. Surplus and tested used.

The small accessories. Transponder keys, key adapters, mounting brackets, door handles and installation tools. Frequently what is actually needed and awkward to source.

We buy Pilz

If you are decommissioning a machine, controllers, modules and safety devices all hold value. See Sell To Us.
