application external switching devices. |
| External switching devices:Any type of
ON/OFF metallic or solid state device, such as relays, push.buttons,
optocouplers, TTL, FETs, switches, transistors, etc. |
| DC/DC converters: One DC/DC converter per
channel supplies 3V @ 5mA to the input optocoupler when the external swiching
device is in ON status. |
