MUR1

Product catalog summary

Overview: The document provides detailed specifications and characteristics of the MUR1 series timers, which are DIN rail mountable and feature a 17.5 mm width with a single relay capable of handling 8A. These timers are available in multi-function or mono-function versions, with multi-range and multi-voltage capabilities. They offer both screw and spring terminal connections and include an LED status indicator.

Specifications:

Functions: Various timing functions including delay on energisation, timing after closing and opening of control contact, timing on energisation with memory, impulse one-shot, pulse output, timing after impulse, flip-flop pause start, and flip-flop pulse start.
Timing Ranges: 0.1 seconds to 100 hours across 7 ranges.
Accuracy: Repetition accuracy is ±0.5% with constant parameters, and display accuracy is ±10% at 25°C.
Supply Voltage: 24 V DC / 24 to 240 V AC with a frequency of 50/60 Hz.
Output: 1 changeover relay with a nominal rating of 8A.
