Time Relay FF PCU-511 DUO, control voltage 230V and 24V AC/DC, multifunction timer

FF PCU-511 DUO is a multifunction time relay designed for control circuits that require compatibility with both 230 V and 24 V AC/DC supply voltages. The device provides accurate timed switching and delay functions suitable for industrial equipment, building automation, and machinery control where a single relay must serve multiple voltage environments. The compact design and multifunction capability allow it to replace or upgrade existing timers while keeping wiring and panel space minimal.

Advantages

The timer supports dual control voltages (230 V and 24 V AC/DC) and integrates several timing modes in one unit, reducing the need for multiple separate devices. It delivers repeatable timing performance and reliable contact switching for control and automation tasks. The compact footprint simplifies installation in control panels and DIN-rail assemblies, while a clear set of terminals enables straightforward wiring. The multifunction nature helps standardize spare parts and maintenance procedures.

Suitable for

• Control and automation circuits in industrial machinery
• Building systems such as ventilation, lighting and access control
• Sequence control and interlocking applications
• Replacement or retrofit where both 230 V and 24 V control voltages are used

Key specifications

• Control voltage compatibility: 230 V and 24 V AC/DC
• Function: Multifunction timer with adjustable timing modes
• Timing range: configurable intervals for delays and cycles (factory documentation specifies available ranges)
• Relay output: mechanical contact(s) for switching loads in control circuits
• Mounting: panel or DIN rail compatible housing for compact installation
• Connection: screw or push-in terminals for secure wiring

How to use

Install the relay in a suitable control panel or DIN-rail enclosure, ensuring the supply voltage selected matches the intended control circuit (230 V or 24 V AC/DC). Connect supply and load wiring to the designated terminals following safety and local electrical regulations. Select the desired timing function and set the timing value according to application requirements using the device controls. After wiring and setting, power the circuit and verify correct operation by observing relay switching during a test cycle.

Usage recommendations

Verify voltage selection and wiring before energizing; use proper overcurrent protection and follow manufacturer instructions for mounting, ambient temperature limits, and preventive maintenance to ensure long-term reliable operation.
