The Metz Connect time relay type 110657 is a multifunction time relay for industrial applications. It enables time-controlled operation of electrical loads and is used in control panels where precise time control is required. The device is designed for operating voltages of 230 V AC and 24 V AC/DC and features an integrated function setting via coding switches. Time adjustment is performed using a linear potentiometer on a relative scale, allowing flexible adjustment of delay or pulse times.

Applications
This time relay is suitable for applications in automation technology, such as in production plants, lighting control systems, or machine control systems. It is used wherever a time-delayed or time-controlled switching function is required, for example for motor protection, pump control, or regulation of heating and cooling systems. The five adjustable functions – On-delay, Off-delay, On-pulse, Blinking starting with pause, and Blinking starting with pulse – allow broad adaptation to different control requirements.

Functions and Equipment in Detail
The device offers eight adjustable time ranges, ranging from 0.15 seconds to 10 hours. Function selection is performed via integrated coding switches, enabling easy selection of the desired operating mode. Time adjustment is carried out using a linear potentiometer mounted on a relative scale. This means that time is set not in absolute values, but in proportion to the scale, ensuring quick and intuitive operation. Connections are made via screw terminals, ensuring a secure and reliable connection.

Technology Explained Simply
The time relay operates with an electronic time control system configured via the potentiometer and coding switches. The integrated coding switches allow selection between five different operating modes, with each function defining a specific switching logic. The time delay is determined by the position of the potentiometer on the relative scale, allowing precise adjustment of the time duration within the selected range. The operating voltage of 230 V AC and 24 V AC/DC ensures broad compatibility with various supply voltages in industrial environments.

Compatibility and Accessories
The time relay is designed for use in control panels with 230 V AC and 24 V AC/DC. It can be used in combination with other control elements, such as relays, contactors, or safety relays, to implement complex control sequences. The screw terminals allow easy integration into existing installations.

Mounting and Installation
Mounting is carried out in standard control panels or enclosures. The screw terminals enable quick and secure connection of the wiring. Operation is performed via the potentiometer and coding switches on the front side of the device.

Advantages in Operation
The time relay offers high flexibility through its five adjustable functions and eight time ranges. Operation via the linear potentiometer on a relative scale enables quick and intuitive adjustment. The use of screw terminals ensures a reliable electrical connection. Compatibility with 230 V AC and 24 V AC/DC extends the application range in various industrial environments. The integrated coding switches simplify selection of the desired operating mode without requiring additional tools or adjustment devices.
