Radio antenna module for the Eltako RS485 bus with replaceable antenna. With integrated switched-mode power supply 12V DC/8W. Bidirectional. Encrypted radio. Stand-by loss only 1 watt. If required, a radio antenna FA250 or FA200 can be connected. Series installation device for mounting on mounting rail. 36mm wide, 58mm deep. Supply voltage 230V. The delivery includes 2 terminating resistors for attachment with imprint, 1/2 TE, 3 jumpers 1 TE (of which 1 replacement), 2 jumpers 1/2 TE (of which 1 replacement) and a jumper assembly tool SMW14. The FAM14 radio antenna module receives and tests all signals from the radio transmitters and repeaters in its reception range. These are passed on via an RS485 interface to downstream RS485 bus switching actuators: Up to 126 channels can be connected to the RS485 bus. Cross-wiring bus and power supply with jumper. The enclosed second terminating resistor must be attached to the last actuator. Up to 128 encrypted sensors can be taught in. Mini-USB
