Turbine Compact Board Connectors

Main PCB

Front

P1 RJ45 PoE port for 10/100 Mbit Ethernet connection.

The station can be powered from this port if the line supports Power over Ethernet (PoE).

P2 5-pin plug-on terminal for relay and external power

Pin 1/2: 24 VDC for external secondary power if PoE is not used. Pin 1 is positive.

Pin 3: COM relay (Common)

Pin 4: NO relay (Normally Open)

Pin 5: NC relay (Normally Closed)

• Relay switching capacity: Max. 60 watt (Max voltage: 250VAC/220VDC. Max current: 2A)
• Connectable conductors: 0.20 - 1.5 mm² (IEC) / 24 - 16 AWG (UL)

P4 Loudspeaker & Electret microphone

Pin 1: Speaker output +

Pin 2: Speaker output -

Pin 3: Electret Microphone +

Pin 4: Electret Microphone -

• Connectable conductors: 0.20 - 1.5 mm² (IEC) / 24 - 16 AWG (UL)
• Recommended loudspeaker impedance: 8 ohms

Note: To enable the electret microphone input when using a TKIS-2, the "Frontboard" 
must be set to "Kit" under Station Main Settings in the web interface of the device.

P3 10-pin plug-on terminal for I/O's and Audio Line Out

Pin 1 5.3V (max. 200mA current)

Pin 2 GND

Pin 3 Button Input or LED Driver

Pin 4 Button Input or LED Driver

Pin 5 Button Input or LED Driver

Pin 6 Button Input or LED Driver

Pin 7 Button Input or LED Driver

Pin 8 Button Input or LED Driver

Pin 9 600 ohm balanced line out +

Pin 10 600 ohm balanced line out -

• Connectable conductors: 0.20 - 1.5 mm² (IEC) / 24 - 16 AWG (UL)

Output Connectors + 1 relay

The extra relay for any of the 6 I/O pins is connected as shown:

Most general purpose P-Channel MOSFET's should work. Recommended example: BSS84

The 5,3V output can deliver 200mA current maximum
