ERD-48M Panel Mount Timer Relay - Universal Digital Timer for Industrial and Home Automation

The ERD-48M panel timer relay is a versatile digital timer designed for controlling time cycles, industrial processes, single-use machines, and home automation. It offers 13 different operating modes, precise programming, and a wide range of control options.

The device allows setting simple time sequences, from 0.1 seconds to 99.59 hours, using buttons on the front panel. The dual LED display makes value visualization clear and legible even from a distance.

Key Features:

• Multifunction digital timer with START / RESET / GATE control inputs

• 13 programmable modes for a wide range of applications

• Time units: hours (99:59) / minutes (99:59) / seconds (599.9 s)

• Last state memory: remembers settings and output status during power outage

• Dual LED Display:

  • Top line (red): set value

  • Bottom line (yellow): current measured time or status

• Indication of OUT relay closure with a red LED

• Integrated power supply for sensors: 12 V DC, max 50 mA

• Compatible with 24 V DC (PNP) signals or custom 12 V output from terminal 9

• Robust construction, 48×48 mm panel mounting

Functions and Controls

The device includes 13 different operating modes, allowing full flexibility in control:

• ON timing
