MCR91504R & MCR91504RE
Four Channel Multicode Series Receiver. MCR91504R
The MCR91504R receiver delivers reliable performance with four relay outputs, each boasting a contact rating of 8 Amps at 240VAC, making it ideal for a variety of industrial and commercial applications. Designed for ease of use, the MCR91504R features pluggable terminal blocks for simple wiring, a high quality SMA antenna connector to ensure excellent signal reception, and a quick mount (QM100) for hassle free installation. For enhanced durability in demanding environments, this receiver is also available in an IP66 rated weatherproof case (MCR91504RE).
Powered by Multicode Technology (MCT), the receiver offers dual digital coding options, including an encrypted coding for high security needs or a 12-way dipswitch for standard applications. This flexibility makes this receiver a versatile and secure solution for a wide range of uses.
These receivers are distinguished by its advanced integration of Frequency Hopping Spread Spectrum (FHSS) and MCT technologies. FHSS, a technology often used in high end military and medical equipment, provides exceptional resistance to interference and eavesdropping. This sophisticated yet user friendly receiver is perfect for applications where reliability, security, and ease of use are paramount.

Elsema: Frequently Asked Questions
What is the Elsema MCR91504R receiver?
The MCR91504R is a 4-channel, high-security receiver operating on the 915MHz frequency band. It is designed to provide four independent relay outputs, making it an ideal choice for complex industrial automation and multi-device control systems.
What is the benefit of Frequency Hopping Spread Spectrum (FHSS) technology?
The Frequency Hopping Spread Spectrum technology allows the receiver to switch between different frequencies automatically. This significantly reduces the risk of signal jamming or interference from other wireless devices, making it highly reliable in electrically noisy environments like factories or warehouses.
What are the load capacities for the four relay outputs?
Each of the four channels features a voltage-free relay output. These relays are rated at 8 Amps at 240VAC, allowing the receiver to handle enough capacity to switch various industrial loads, motors, and lighting systems directly.
What coding options does the MCR91504R support?
The receiver offers dual digital coding options:
- 12-Way Dipswitch: For simple, manual code matching between the transmitter and receiver.
- Encrypted Coding: A high-security encrypted code (with over 16 million combinations) programmed wirelessly for protection against unauthorized access.
Can the MCR91504R be used for outdoor applications?
The standard MCR91504R is an open-board unit for protected environments. For outdoor use, Elsema offers the MCR91504RE, which is housed in an IP66-rated weatherproof enclosure to protect the electronics from rain and dust.
What is the typical operating range of the MCR91504R?
When used with a external 915MHz antenna, the MCR91504R has an operating range of up to 350 metres in line-of-sight conditions. This range makes it suitable for expansive industrial sites, farms, or large commercial properties.
What are the different output modes available?
Users can select between Momentary and Latching modes for each relay via an on-board 4-way dipswitch:
- Momentary: The relay stays on only while the transmitter button is held.
- Latching: The relay toggles between ON and OFF with each press (like a light switch).
How many remotes can I program into a single receiver?
The MCR91504R offers unlimited remote storage. Because it relies on matching the 12-way dipswitch or an encrypted key, you are not limited by internal memory slots, allowing a single receiver to support hundreds or thousands of users.
What power supply is required for the MCR91504R?
The receiver is designed for wide compatibility, operating on a supply voltage between 12 and 24 Volts AC or DC. This versatility allows it to be powered directly from most gate control boards or industrial power supplies.
Is the installation process straightforward?
Yes, the receiver is designed for professional efficiency. It features pluggable terminal blocks for fast wiring, a high-quality SMA antenna connector for superior reception, and is compatible with Elsema’s QM150 quick-mount system.
