KURODA RCS2413-01-D24L-Z Replacement for FONTAL Series

Product Overview

KURODA RCS2413-01-D24L-Z Replacement for FONTAL Series: Seamless Transition from Legacy Pneumatic Control Systems

The KURODA RCS2413-01-D24L-Z is a direct-acting solenoid valve from KURODA’s FONTAL series, rated at DC24V with an R1/8 port connection and integrated LED indicator. As industrial facilities phase out aging pneumatic control architectures — including legacy valve manifolds, discontinued pilot-operated valves, and first-generation directional control assemblies — the RCS2413-01-D24L-Z provides a verified drop-in replacement path that minimizes rewiring, reduces commissioning time, and preserves existing tubing layouts.

Many facilities operating older KURODA RCS-series or equivalent third-party solenoid valves encounter supply chain disruptions when original part numbers are discontinued or lead times extend beyond acceptable maintenance windows. The RCS2413-01-D24L-Z addresses this directly: its R1/8 threaded port is compatible with standard pneumatic manifold blocks and inline fittings used across a wide range of automation panels, and its DC24V coil rating aligns with the 24VDC control voltage standard found in the majority of PLC-driven I/O output modules — including sink/source transistor output cards from Mitsubishi MELSEC, Siemens S7-300/S7-1200, Omron CJ/CS series, and Keyence KV series controllers.

In retrofit scenarios, engineers replacing older RCS-series valves or equivalent FONTAL-type units will find that the coil connector pinout and DIN rail-compatible valve body dimensions of the RCS2413-01-D24L-Z match common industry standards, reducing the need for custom adapter brackets or connector rework. The integrated LED indicator simplifies field diagnostics — technicians can visually confirm valve energization without a multimeter, which is particularly valuable during live commissioning or fault-finding on densely wired control panels.

For systems where the solenoid valve is driven by a PLC digital output module — such as a Mitsubishi QY10 transistor output unit, an Omron CJ1W-OD211, or a Siemens SM 322 DO module — the RCS2413-01-D24L-Z’s DC24V coil draws within the standard current budget of most 24VDC output channels, eliminating the need for intermediate relay amplification in most applications. Where relay isolation is still required (e.g., in high-cycle or safety-rated circuits), standard DIN rail relay modules such as Phoenix Contact or Weidmüller relay bases can be inserted without modifying the valve wiring harness.

Seamless Upgrade Solutions

A complete pneumatic control upgrade typically involves more than a single valve replacement. When migrating from a legacy system, procurement teams and maintenance engineers commonly source the following components alongside the RCS2413-01-D24L-Z to ensure a fully integrated and tested assembly:

For systems using valve manifold blocks — such as KURODA’s own multi-station manifold bases or equivalent SMC VQ/SY series manifold rails — the RCS2413-01-D24L-Z can be mounted in multi-valve configurations, sharing a common supply port and reducing individual pipe connections. Where the existing manifold uses a D-sub or multi-pin connector for centralized wiring, a DIN rail-mounted terminal block module (e.g., Phoenix Contact PTFIX or Weidmüller WDU series) provides a clean interface between the PLC output card and the valve coil wiring harness.

In control cabinets where 24VDC power distribution is managed by a MEAN WELL SDR-series or OMRON S8VS power supply unit, the RCS2413-01-D24L-Z integrates without additional power conditioning. For applications requiring electrical isolation between the PLC output and the valve coil — particularly in CE-marked or safety-assessed panels — a slim relay module such as a Phoenix Contact PLC-RSC or an Omron G2RV relay socket provides the necessary isolation barrier while maintaining the 24VDC control signal standard.

Where the solenoid valve is part of a larger pneumatic axis controlled by a servo drive or stepper driver — for example, a Mitsubishi MR-J4 servo amplifier coordinating with a pneumatic clamp or gripper — the valve’s fast response time and direct-acting design support synchronized motion sequences without introducing latency into the control loop. Signal conditioning modules such as WAGO 750-series analog input cards or Beckhoff EL1xxx digital input terminals can be used to monitor valve feedback signals within the same I/O rack.

For facilities upgrading HMI visualization alongside the valve replacement, GOT2000 series HMI panels (Mitsubishi) or Siemens KTP700 Basic panels can display valve status via the PLC’s digital input channel connected to the valve’s return signal or pressure switch feedback, providing operators with real-time pneumatic system status without additional field wiring.

Retrofit Guidance FAQ

Q: Can I replace my existing FONTAL-series solenoid valve with the RCS2413-01-D24L-Z without modifying the tubing?
A: In most cases, yes. The R1/8 port size is a standard thread used across KURODA FONTAL-series valves. Verify the existing fitting type (R/PT thread vs. NPT) before installation. If the existing system uses NPT fittings, a thread adapter is required.

Q: Is the coil connector compatible with my existing wiring harness?
A: The RCS2413-01-D24L-Z uses a DIN 43650 Form A connector, which is the most common industrial solenoid valve connector standard. If your existing harness uses a flying lead or a different DIN form factor, a connector adapter or short pigtail extension resolves the mismatch without rewiring the panel.

Q: Will the DC24V coil overload my PLC output module?
A: Direct-acting solenoid valves in this class typically draw 0.5–1.5W at steady state. Most 24VDC transistor output channels (e.g., Mitsubishi QY10, Omron CJ1W-OD211) are rated for 0.1–0.5A per point. Verify the inrush current specification against your output module’s per-point current rating. For high-cycle applications, a relay interposing module is recommended.

Q: What communication protocol does this valve support?
A: The RCS2413-01-D24L-Z is a discrete on/off solenoid valve controlled by a 24VDC digital signal. It does not use fieldbus communication (no IO-Link, PROFIBUS, or EtherNet/IP interface). Control is via standard digital output from any PLC or relay logic system.

Q: How do I confirm the valve is energized during commissioning?
A: The integrated LED indicator illuminates when the coil is energized, providing immediate visual confirmation without test equipment. This is particularly useful during initial loop checks and fault isolation in multi-valve manifold assemblies.

Q: What is the physical installation space requirement?
A: The FONTAL-series body dimensions are compact and suitable for standard DIN rail panel layouts and inline pipe mounting. Confirm the valve body length and port-to-port distance against your existing manifold or pipe bracket before ordering if space is constrained.
