MR-GU1M2P-TR2

Product catalog summary

Overview: The MR-GU1M2P-TR2 is a multifunction monitoring relay designed for DC and AC voltage monitoring in a 1-phase network. It features adjustable thresholds, fault latch mode, and timing adjustments for start-up suppression and tripping delay. The relay is housed in an industrial cover and is suitable for direct mounting on a 35 mm rail.

Specifications:

Output Circuit: 2 changeover contacts, rated voltage of 250 V AC, and a maximum breaking capacity of 750 VA (3 A / 250 V AC) or 1,250 VA (5 A / 250 V AC).
Input Circuit: Supply voltage range of 12 to 400 V AC, with a power consumption of 2.0 VA / 1.5 W.
Measuring Circuit: Capable of measuring DC or AC sinusoidal voltages from 16.6 to 400 Hz, with overload capacities and input resistances specified for 30 V, 60 V, and 300 V AC/DC.
Insulation: Rated surge voltage of 4,000 V, overvoltage category III, and insulation pollution degree 3.
General Data: Electrical life of over 200,000 cycles at 1,000 VA, mechanical life of over 20 million cycles, dimensions of 90 x 22.5 x 108 mm, and weight of 100 g.
Environmental Conditions: Operating temperature range of -25 to +55°C, storage temperature range of -25 to +70°C, and relative humidity of 15 to 85%.

Functions:

Overvoltage and Undervoltage Monitoring: The relay can monitor overvoltage and undervoltage conditions with or without fault latch mode. It uses LED indicators to show the status of the supply voltage, start-up suppression time, and tripping delay.
Window Function: Monitors voltage within a specified range between MIN and MAX values, with fault latch mode available.

Installation and Mounting: The relay is designed for direct mounting on a 35 mm rail according to PN-EN 60715 standards. It requires a TR2 supply transformer, which must be ordered separately and installed by removing the protective cap from the relay.

Precautions: Ensure the product is used within its specified parameters, avoid touching live parts, and ensure correct connection to prevent malfunction or fire risk. For critical applications, a double safety system is recommended.

MR-GU1M2P-TR2 monitoring relays Functions When the supply voltage U is applied, the output relay R switches into on-position (yellow LED illuminated) and the set interval of the start-up suppression (Start) begins (green LED flashes). Changes of the measured voltage during this period do not affect the state of the output relay R. After the interval has expired the green LED is illuminated steadily. For all the functions the LEDs MIN and MAX are flashing alternating, when the minimum value for the measured voltage was chosen to be greater than the maximum value.
