\"\"<\/p>\n

The simply constructed analog 4-way distributor enables the PTT signal to be passed on to up to 4 outputs almost instantaneously.\u00a0For example, several PAs can be addressed at the same time by pressing the PTT button.\u00a0A status LED signals to the user that a PTT signal is present. The PTT input and the outputs are designed as RCA sockets.\u00a0The power supply (9 – 15 V) is provided via a barrel connector; a suitable cable with an open end is included. The fully assembled board is available both individually and completely in a compact, blue aluminum housing.<\/p>\n

Parameters:<\/b><\/p>\n

 <\/p>\n<\/div>\n

– Sequencer delay is fixed 60 ms<\/div>\n
– Sequencer from RX to TX PTT IN to: T0 = 0 ms, T1 = 60 ms, T2 = 120 ms, T3 = 180 ms<\/div>\n
– Sequencer from TX to RX PTT IN to: T0 = 0 ms, T1 = 180 ms, T2 = 120 ms, T3 = 60 ms<\/div>\n
– Optocoupler isolator protection at PTT IN port<\/div>\n
– OUTPUTS are open while input PTT is in RX, shorted to GND while input is in TX<\/div>\n
– When you need to switch positive voltage (LNA) you can use P-FET switch example<\/div>\n
– Input PTT logic: active when grounded<\/div>\n
– Input PTT logic current typ. 15mA<\/div>\n
– Output FET switch 50V 500mA for each port<\/div>\n
– DC power supply 9 V to 15 V typ. 30 mA DC cable connection (included for enclosure version)<\/div>\n
