TURCK MS13-S01-R/M23 Replacement/Upgrade Solution for MS Series

Product Overview

TURCK MS13-S01-R/M23 Replacement/Upgrade Solution for MS Series: Smooth Transition from Legacy Safety Systems

When your existing safety switching amplifier reaches end-of-life or becomes obsolete within a legacy machine-safety architecture, sourcing a verified drop-in replacement is critical to minimizing unplanned downtime. The TURCK MS13-S01-R/M23 is a single-channel safety switching amplifier from TURCK’s proven MS Series, designed for direct integration into safety relay circuits, emergency-stop loops, and two-hand control systems. Whether you are retiring an older TURCK MS11 or MS12 variant, migrating from a third-party safety relay module, or simply replenishing critical spare inventory, this unit delivers the electrical and mechanical compatibility your control cabinet demands.

The M23 connector interface is a key advantage during retrofit projects. Unlike bare-wire or screw-terminal alternatives, the M23 circular connector format allows technicians to disconnect and reconnect the amplifier without disturbing the existing cable harness — a significant benefit when working inside a densely populated control cabinet where rewiring would introduce risk and extend commissioning time. The connector pinout is consistent with the broader TURCK MS Series family, meaning that a cabinet previously wired for an MS11-S01-R/M23 or MS12-S01-R/M23 can accept the MS13-S01-R/M23 without cable modification.

Power supply compatibility is another critical factor in any safety system upgrade. The MS13-S01-R/M23 operates on a standard 24 V DC supply, consistent with the majority of modern PLC-based safety architectures. This means the existing 24 V DC rail in your control cabinet — whether sourced from a TURCK PSU or a third-party DIN-rail power supply — can power the replacement unit directly. No additional transformer, voltage converter, or power conditioning equipment is required.

Seamless Upgrade Solutions

A successful safety system migration rarely involves a single component. In practice, upgrading the MS13-S01-R/M23 is most effective when coordinated with the surrounding safety architecture. During commissioning, engineers frequently pair this amplifier with a TURCK BL20 gateway module to bridge the hardwired safety circuit into a PROFINET or EtherNet/IP network segment, enabling remote diagnostics without altering the core safety loop. Where the existing cabinet uses a TURCK FEN20-4IOL IO-Link master, the MS13 can be integrated into the same DIN-rail assembly, sharing the 24 V DC bus and simplifying cable management.

For projects migrating from older Siemens S5 or early S7-300 safety PLCs, the MS13-S01-R/M23 is commonly installed alongside a Siemens 3SK1111-1AB30 safety relay or a Pilz PNOZ X2.8P to form a hybrid safety layer during the transition period — allowing the new amplifier to be validated in parallel with the legacy system before full cutover. In cabinet layouts where space is constrained, the compact housing of the MS13 pairs well with TURCK IM12-14EX-I/24VDC signal isolators mounted on the same rail, maintaining signal integrity between the safety amplifier output and the PLC input card.

Wiring continuity is preserved when the M23 cable assembly — such as a TURCK RKM 40-2M or equivalent M23 cordset — is reused from the decommissioned unit. This eliminates the need to re-terminate field cables, which is particularly valuable in food-processing or pharmaceutical environments where cable routing is fixed and documented. Where the safety circuit feeds into a TURCK TBPN-L1-FDIO1-2IOL remote I/O block, the relay output of the MS13 can be wired directly to the digital input channel without additional signal conditioning. For installations requiring monitored manual reset, the MS13 integrates cleanly with standard TURCK B1N360V-Q20L60-2LU3-H1151 inductive safety sensors already present in the machine guarding circuit.

Retrofit Guidance FAQ

Q: Can I reuse the existing M23 cable harness from the old MS11 or MS12 unit?
A: Yes. The M23 connector pinout is consistent across the TURCK MS Series. The existing cable assembly can be disconnected from the old unit and connected to the MS13-S01-R/M23 without re-termination, provided the cable is in serviceable condition.

Q: Do I need to modify my PLC safety program after replacing the amplifier?
A: In most cases, no. The MS13-S01-R/M23 presents the same relay output behavior as its predecessors. If your safety PLC (e.g., Siemens S7-1500F or Allen-Bradley GuardLogix) monitors the relay contact state, the logic block does not require modification. Verify the output contact rating against your PLC input card specification before energizing.

Q: Is the MS13-S01-R/M23 compatible with PROFIBUS or PROFINET safety protocols?
A: The MS13 operates as a hardwired safety device and does not natively support fieldbus protocols. It interfaces with the safety PLC via relay contacts. If fieldbus integration is required, a gateway module such as the TURCK BL20 series can be used to monitor the relay state over PROFINET without compromising the hardwired safety function.

Q: What is the physical footprint, and will it fit in my existing cabinet layout?
A: The MS13-S01-R/M23 uses the standard TURCK MS Series housing, which mounts on a 35 mm DIN rail. The width and depth are consistent with MS11 and MS12 variants, so no cabinet rework or rail extension is required for a direct swap.

Q: How do I handle the monitored reset function during commissioning?
A: The monitored manual reset input is wired identically to the legacy MS Series configuration. Connect the reset pushbutton to the designated input terminals per the MS13 wiring diagram. After installation, perform a full safety function test — including fault injection and reset verification — before returning the machine to production.

Q: What if the original unit was from a third-party brand, not TURCK?
A: Cross-brand replacement is feasible if the third-party unit used a compatible M23 connector and 24 V DC supply. Verify the output relay contact rating, safety category, and reset behavior against the MS13 datasheet. TOPNLMS technical support can assist with cross-reference validation prior to purchase.
