Description

The GLR08 can be connected with the R433 data receiver to form an 8-channel receiver. Connecting both units is simple. The GLR08 has a 3-way terminal block marked as + D - which should be connected directly to the R433 3-way terminal block marked as + D - . If the R433 is with a plastic case the connection is via a socket which is marked + D - . This connection is graphically shown at the bottom. The receiver can be used with the GLT08 / T433 transmitter to give an operating range of 1 Kilometres, line of sight, for each of the eight channels.

Each channel is addressed via the terminal block or the IC socket. The channel is activated when the corresponding channel number is shorted to ground. Each of the eight digital channel codes is stored in a microcontroller, which replaces the traditional dip switch.

The GLR08 and R433 can be purchased with Elsema's C160 weatherproof case and ANT433S UHF antenna.

Channels

The eight channels are solid state outputs using the ULN2803 Integrated Circuit. This IC is inserted to a socket that enables the user to easily change the output stage in case of a damaged output. The ULN2803 IC is available from Elsema. Output 1 being at the left and output eight to the right of the terminal block.

Different Modes for each Output

Modes are user selectable from the 3-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": Outputs on, only while correct signal is received
"All Flip-Flop": Outputs alternate at every correct incoming signal
"Momentary & Flip-Flop": Outputs 1-4 are momentary & 5-8 are flip-flop
"Latching on": Outputs will be on until supply to receiver is momentarily interrupted
"Momentary & Flip-Flop": Outputs 1-6 are momentary & 7-8 are flip-flop
"Momentary & Flip-Flop": Outputs 1-2 are momentary & 3-8 are flip-flop
"Momentary & Flip-Flop": Outputs 1-3 are momentary & 4-8 are flip-flop
"Latching on": Output 1 is latching & 2-8 are momentary

Case

The GLR08 can be supplied with or without a case. This allows the receiver to be integrated according to your needs.
