MCR91512R & MCR91512RE
Twelve Channel Multicode Series Receiver. MCR91512R
The MCR91512R receiver is a highly reliable solution featuring 12 relay outputs, each with a robust contact rating of 8 Amps at 240VAC, making it ideal for a wide range of industrial and commercial applications. Designed with user convenience in mind, the receiver has screw type terminal blocks for easy wiring, a high quality SMA antenna connector for superior signal reception. For enhanced durability in challenging environments, this receiver is also available in an IP66 rated weatherproof case (MCR91512RE).
Equipped with advanced Multicode Technology (MCT), the MCR91512R offers dual digital coding options: encrypted coding for high security requirements or a 12-way dipswitch for standard applications. This flexibility ensures that this receiver can adapt to a broad spectrum of applications, providing enhanced security where needed.
The MCR series stands out with its sophisticated integration of Frequency Hopping Spread Spectrum (FHSS) and MCT technologies. FHSS, a technology widely used in high end military and medical equipment, provides exceptional resistance to interference and eavesdropping. This advanced yet user friendly receiver is perfect for applications where reliability, security, and ease of use are essential.

Elsema: Frequently Asked Questions
What is the main function of the MCR91512R receiver?
The MCR91512R is a 12 channel industrial-grade receiver that uses 915MHz technology for wireless control. It is designed to provide twelve independent relay outputs, making it ideal for complex automation tasks where multiple devices such as pumps, gates, and industrial machinery need to be controlled from a single location.
How many devices can I control with this receiver?
This model features 12 independent relay outputs. Each channel can be assigned to a different function or device, allowing you to manage a wide array of equipment simultaneously from a compatible 12-button transmitter like the MCT91512.
What is the benefit of Frequency Hopping Spread Spectrum technology?
The receiver utilises Frequency Hopping Spread Spectrum (FHSS) technology, which automatically switches between different frequencies within the 915MHz to 928MHz band. This ensures that the system remains immune to interference and jamming, allowing multiple receivers to operate in the same area.
What are the electrical ratings for the relay outputs?
Each of the 12 relays is rated at 8 Amps at 240VAC. This high rating allows the receiver to switch significant electrical loads directly without always requiring secondary high-power contactors.
Can I mix different output modes (Momentary and Latching)?
Yes. The receiver features a 4-way DIP switch that allows you to select from different operational modes. These modes include:
- Momentary: Relay stays active only while the button is pressed.
- Latching: Relay toggles on/off with each press.
- Mixed Modes: Specifically configured combinations where some channels are momentary and others are latching.
What coding options does the MCR91512R 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.
What is the power requirement for the board?
The receiver operates on a wide supply voltage range of 12 to 24 Volts AC or DC. In standby mode, it consumes only 30mA, and with all 12 relays active, the current consumption is approximately 270mA (at 12VDC).
What is the maximum range I can expect?
When used with an ANT915S antenna under clear line-of-sight conditions, the MCR91512R has an operating range of up to 400 metres.
Can I use multiple receivers in the same area?
Yes, Frequency Hopping Spread Spectrum technology allows you to operate multiple receivers in the immediate vicinity without any interference issues.
Is there a weatherproof version for outdoor use?
While the MCR91512R is an open board designed for enclosure mounting, Elsema offers the MCR91512RE. This version comes pre-installed in an IP66-rated weatherproof case, making it suitable for mounting directly onto walls or poles in outdoor environments.
