Vestec PN2548 Detector Voltage Delay Timer Module

The Vestec PN 25-48 Voltage Delay Timer is a panel-mounted electronic assembly that provides voltage sensing with a time-delay operation for industrial control and monitoring systems. It is designed for detector circuits, process control panels, and monitoring circuits where a controlled, voltage-triggered timing sequence is required, delivering delayed switching to support reliable sequencing and improved system protection, and it is used as a replacement component for existing Vestec control systems. Common replacements include Omron H3CR Series Time Delay Relay, Macromatic TR-6512U Voltage Delay Relay, and SSAC TRDU Series Time Delay Relay; the unit is manufactured by Vestec with origin in Czechia and is commonly found as used surplus in industrial channels.
