Panel Time Relay ERD-48M - Universal digital timer for industrial and home automation

The ERD-48M panel clock relay is a multi-purpose digital timer designed for time cycle control, industrial processes, single-purpose machines and home automation. It offers thirteen different operating modes , precise programming and a wide range of control options.

The device allows for easy time setting from 0.1 seconds to 99.59 hours using the front panel buttons. The dual LED display makes the display of values ​​clear and readable even from a distance.

Main features:

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

• 13 programmable modes for a wide range of applications

• Time units: hour (99:59) / minute (99:59) / second (599.9 s)

• Last state memory - remembers settings and output status even in the event of a power failure

• Dual LED display:

  • Top line (red): set value

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

• Indication of OUT relay closure with red LED

• Built-in power supply for sensors: 12 V DC, max. 50 mA

• Compatible with 24 VDC (PNP) signals or individual 12 V output from terminal 9

• Robust construction, can be mounted in a 48×48 mm panel

Features and controls

The device includes 13 different operating modes that provide complete flexibility in control:

• Timed switch-on

• Time delay off

• cyclical on/off
