Turbine Extended connectors

Item	Description	Comment
1¹	2 Relays	Double Throw (SPDT) relay contact with 60W switching power. Max: 250VAC/220VDC, 2A, 60W
2¹	I/O interface	6 general purpose I/Os. Each I/O can be configured either as an input or 12mA LED driver output
3¹	Line Output	Balanced 600 ohm audio line out. Suitable for external induction loop amplifier, PA amplifiers etc
4¹	Speaker Output	Connection for 8 ohm loudspeaker
5¹	Microphone Input	Electret mic input
6	TA-10 connector	Connection for TA-10 Relay Module
7¹	Power Input	Optional 24VDC power input from external power supply (if PoE is not provided)
8	LAN Port	Dual 10/100Mbps RJ-45 port for Ethernet connection (inbuilt switch). PoE is supported
9	AUX	Auxiliary connector for Handset and Headset, and Line IN * Headset/handset speaker (pin 6/7): Minimum 32 Ohms * Microphone input (pin 4/5): For electret type. Bias voltage is 1,25V. * Line In: Maximum input level is 1.228 Vrms (Professional line level).

¹) Connectable conductors: 0.20 - 1.5 mm² (IEC) / 24 - 16 AWG (UL). Use of ferrules is recommended. Max cable size is then 0.75 mm².

Relay switching capacity: Max. 60 watt (Max voltage: 250VAC/220VDC. Max current: 2A) The 5,3V output can deliver 200mA current maximum

If connected to two PoE-capable switches, only one of the ports will negotiate PoE; hence this is not a good solution for power redundancy (switch failure might lead to a reboot). Instead a “dumb” PoE injector (spare-pair power) should be used for the two Ethernet ports or a local 24 VDC local power backup. If used together with PoE the station can be powered by 24 VDC as a local power backup.
