1. Voltage Monitoring Relay (Spannungsüberwachungsrelais) - What it is and why you need it - A device that monitors input voltage and signals when voltage is outside programmable limits. - Helps protect motors, drives, PLCs, and power supplies from undervoltage and overvoltage conditions. - Reduces unexpected equipment trips and associated downtime. - How it works - Monitors the supply voltage and compares it to user adjustable high and low thresholds. - Uses hysteresis and minimal response delay to prevent nuisance trips. - Provides a relay output that can be wired into control circuits or interlocks. - Key attributes - Function: voltage supervision with configurable limits and a relay output. - Compatibility: suitable for standard industrial control circuits; designed for common panel installations. - Size and mounting: compact form factor for panel mounting in control cabinets; compatible with typical mounting schemes in industrial environments. - Material and build: robust enclosure intended for use in demanding environments. - Performance: reliable voltage monitoring with stable switching across a wide operating range. - Typical applications - Protect CNC machines and drives by tripping when input voltage falls outside acceptable range. - Guard essential power rails for PLCs and automation cabinets to prevent unexpected faults. - Provide alarms or interlocks in data centers or telecom equipment racks when supply voltage deviates. 2. Time Relay (Zeitschaltrelais) - What it is and why you need it - A timing relay that introduces a controlled delay in switching a load. - Supports sequencing, interlock functions, and controlled start/stop of equipment. - Improves process reliability and protects devices from sudden changes or inrush. - How it works - Accepts a trigger signal and starts a user adjustable delay. - Activates or deactivates the relay output after the set delay, depending on the configuration. - Can support repeatable or single-shot timing modes as offered by the device. - Key attributes - Function: adjustable delay timing with a relay output. - Compatibility: designed for standard control circuits and common supply voltages; suitable for panel or DIN rail mounting. - Size and mounting: compact, rugged enclosure appropriate for control panels. - Material and build: durable housing for industrial environments. - Performance: accurate, repeatable timing with stable operation over typical industrial temperature ranges. - Typical applications - Delay motor start to reduce inrush and protect electrical components in conveyors or fans. - Sequence control for multi-device operations, such as lights, pumps, or actuators in machinery. - Hold-off or interlock timing in safety circuits to ensure proper ordering of operations after an event. Note: This description preserves the function and intent of Voltage Monitoring Relays and Time Relays for industrial control use. It emphasizes practical benefits, compatibility with standard control architectures, and typical applications without added or omitted technical specifics.
