8 Channel SSR / logical output board
Product Code: A8SSR
The 8 Channel SSR / logical
output board provides 8 SSR output channels and 8 logical output
channels. The SSR can be treated as a relay. Each SSR channel can be
used to control ON/OFF of external devices, to drive external high
power devices to activate alarms. Etc. There are 8 LED indicators
correspond to 8 SSR channels, when SSR is energized, the corresponding
LED is light.
The output voltages of logical output channel are user selectable; user may select +5V, 12V, or the external voltage lower than 40V DC. There are 8 LED indicator corresponds to 8 logical output channels, when output voltage is low, then the corresponding LED is light.
The output voltages of logical output channel are user selectable; user may select +5V, 12V, or the external voltage lower than 40V DC. There are 8 LED indicator corresponds to 8 logical output channels, when output voltage is low, then the corresponding LED is light.

2.1 Configuration For Jumper
Before you use the 8 Channel SSR/ Logical Output board, you must ensure that the jumpers and connectors are set correctly. Observe the figure in the following, the proper settings for the 8 Channel SSR / Logical Output boards are described in the follows.

|
| JP1
is used to select output voltage, when JP1-1 is short, then the output
voltage is 5V. When the Jp1-2 is short, we select 12V as the output
voltage. Suppose the output voltage we required is not 5V or 12V, the
JP1-3 is short, to use the VEXT voltage. TB3 is used to connect external power; the configuration is shown in the follows. The maximum input voltage is 40V DC. |
