MAR1

Product catalog summary

Product Overview: The MAR1 Timer is a DIN rail mountable device with a 17.5 mm width, featuring a single relay with an 8A capacity. It offers both multi-function and mono-function capabilities, multi-range and multi-voltage options, and can be connected via screw or spring terminals. The device includes an LED status indicator and supports external load connections in parallel to the control input. It is compatible with 3-wire PNP sensors.

Specifications:

Functions: Timing ranges from 0.1 seconds to 100 hours with a changeover relay output rated at 8A.
Connections: Screw terminals with a supply voltage of 24 V DC or 24 to 240 V AC.
Timing Accuracy: Repetition accuracy is ±0.5% with constant parameters, and display accuracy is ±10% at 25°C.
Supply: Multi-voltage power supply with a frequency of 50/60 Hz and an operating range of 85 to 110% Un.
Output Specification: Rated power of 2000 VA/80 W with a maximum breaking current of 8 AAC at 250 VAC resistive.

General Characteristics:

Conforms to standards IEC/EN 61812-1, IEC/EN 61000-6 series, and is certified by CE, UL, cUL, CSA, GL.
Temperature limits for use range from -20°C to +60°C, with storage limits from -30°C to +60°C.
Protection ratings include IP20 and IP40, with a front face protection of IP50.
Electromagnetic compatibility includes immunity to electrostatic discharges and radiated electromagnetic fields.

Installation and Connections:

Designed for symmetrical DIN rail 35 mm installation.
Terminal capacity varies for single-wire and multi-wire connections, supporting both flexible and rigid wires.
Housing material is self-extinguishing, and the device has undergone shock and vibration resistance testing.

Dimensions and Weight: The casing measures 17.5 mm and weighs approximately 63 grams, depending on the model.
