FMR15108 8-Channel 151MHz Receiver with Open Collector Outputs ELSEMA 8-Channel 151MHz Receiver with Open Collector Outputs, FMR15108 Features · Eight channel receiver with open collector outputs · Supply voltage can be 12 24 Volts AC or DC · Low current consumption · Built-in noise or signal strength indicator · User can select 8 different frequencies · Momentary, Latching and Security latching modes are all user selectable · Easy code setup with dip switch settings · Optional QM100 bracket available for easy mounting to cases or walls. C1015 or C1020 case is also available Applications · Pump Control · Long distance panic button · On/Off applications in agricultural devices · Security alarm · Basic Telemetry eg. Water level indication Description This receiver gives you eight open collector outputs. The output mode can be set to momentary, latching or security latching. The user can select 8 different narrow band frequencies and program unlimited number of transmitters to the receiver. With a narrow band FM 151MHz signal from the transmitter a line of sight operating range of 5000 metres is possible. The receiver uses a crystal oscillator circuit that ensures high frequency stability allowing optimal performance in the receiving range. - 1 - ELSEMA 8-Channel 151MHz Receiver with Open Collector Outputs, FMR15108 Different Modes for each Output Modes are user selectable from the 4-way dip switch, shown below. DIP Switch Mode Settings The output relay will respond in the following manner when receiving the correct signal from a transmitter "All Momentary": Relay on, only while correct signal is received "All Latching": Outputs alternate at every correct incoming signal "Momentary & Latching": Outputs 1-4 are momentary & 5-8 are latching "Security Latching on": Outputs will be on until supply to receiver is momentarily interrupted "Momentary & Latching ": Outputs 1-6 are momentary & 7-8 are latching "Momentary & Latching ": Outputs 1-2 are momentary & 3-8 are latching "Momentary & Latching ": Outputs 1-3 are momentary & 4-8 are latching "Security Latching on": Output 1 is security latching & 2-8 are momentary " Security Latching on ": Output 1-7 is latching & 8 is momentary. Momentary - Output is active for as long as the transmitter button is pressed. This is a standard mode on most automatic gates or garage door openers. Latching - Output remains active until next press of the transmitter button. Similar to switching "on" and "off" a light. Security - Output remains active until power to the receiver is removed. Similar to security alarms Latching and fire alarms. Customised Software Custom output modes can be programmed to do special functions. Call Elsema for more details. Coding The 12 way dip switch on the receiver sets the 12 bit unique code for the system. This has to be matched to that on the transmitter. Do not use the factory default code. - 2 - ELSEMA 8-Channel 151MHz Receiver with Open Collector Outputs, FMR15108 Signal Strength Indicator The 151MHz receivers have five blue LED's on the board. The table below indicates the level of the valid transmitted signal. 5 LED's on 4 LED's on 3 LED's on 2 LED's on 1 LED on -70dBm -75dBm -80dBm -90dBm -100dBm Very Strong signal Very Strong signal Very Strong signal Strong signal Good signal Very Reliable operating conditions Very Reliable operating conditions Very Reliable operating conditions Very Reliable operating conditions Reliable operating conditions Noise Strength Indicator If more than 1 led is "ON" without a valid transmission, this indicates that there is noise on the frequency selected. Change the 3-way dipswitch on the receiver module to select a different frequency. Following is a table with the Dipswitch settings and the corresponding frequencies. Frequency 151.600 MHz 152.375 MHz 151.775 MHz 151.400 MHz 151.175MHz 151.025 MHz 150.900 MHz 150.825 MHz 1 2 3 On On On Off On On On Off On Off Off On On On Off Off On Off On Off Off Off Off Off - 3 - Technical Data Supply Voltage ELSEMA 8-Channel 151MHz Receiver with Open Collector Outputs, FMR15108 12 24 Volts AC or DC. Can use Elsema's AC power pack (12PP-1000) Supply lines should be less than 3 metres long to comply with radio frequency authorities. Current Consumption 22mA Standby at 12VDC, 35mA if all outputs "On" Receiving Freq 151.6MHz (8 selectable frequencies. See table above) Operating Temperature Range -5 to 50°C Sensitivity Better than 0.5uV (For output to activate) Type of Demodulation Narrow-Bandwidth Frequency Modulation (FM) Eight Open Collectors (See chart for Collector Currents) Output Chart indicates that eight outputs can be ON simultaneously with each output collector current being 125mA. Outputs can hold 40 Volts in "Off" state. Connections Supply, Antenna & Outputs - Screw type terminal block Antenna 50, 151MHz Antenna, Elsema ANT151M for maximum performance A piece of approximately 1metre wire can be used for short range applications Dimensions 90 X 70 X 15 mm Mounting hole size 3.97 mm or 5/32" Weight 83g Microcontroller Can be re-programmed to suit your customised needs Useable Transmitters All FMT151 series (with correct setting on the dip switch).

This is done by connecting diodes across your DC inductive load. Inductive loads such as DC relays must be clamped with a diode across the relay coil. If this is not done the spikes generated by the DC relay can lock-up the receiver. When a lock-up occurs you will need to remove the power and re-connect it.
