Eltako wireless antenna module for the Eltako RS485 bus with interchangeable antenna. With integrated power supply 12V DC/8W. Bidirectional. Encrypted wireless communication. Standby loss is only 1 watt. If needed, a wireless antenna FA250 or FA200 can be connected. It is a rail-mounted device for installation on a mounting rail. 36 mm wide, 58 mm deep. Supply voltage 230V. The package includes 2 termination resistors with printed labels, 1/2 TE, 3 jumper bridges 1 TE (including 1 spare), 2 jumper bridges 1/2 TE (including 1 spare), and a jumper bridge mounting tool SMW14. The wireless antenna module FAM14 receives and checks all signals from the transmitters and repeaters within its reception area. These are forwarded via an RS485 interface to downstream RS485 bus switching actuators: Up to 126 channels can be connected to the RS485 bus. Cross-wiring for bus and power supply is done with jumper bridges. The included second termination resistor must be attached to the last actuator. Up to 128 encrypted sensors can be learned in. Mini-USB for connecting a PC to create a device list, configure the actuators using the PC tool PCT14, and for data backup. A legalization code for downloading PCT14 is included with the FAM14. If the load exceeds 50% of the rated power of 8W, a half unit ventilation gap with the spacer is required on the left side.
