The Wireless Analogue Output Modules provide a configurable analog output for a single T24 radio telemetry acquisition module. The output can be selected from the pre-calibrated voltage and current ranges of 0-10Volts, ±10Volts, 0-5Volts, ±5Volts, 0-20mA and 4-20mA (All current outputs both sink and source).
The LED indictors on the T24-AO1 provide status indication of the condition of the radio link, remote battery life and remote sensor status.
These Wireless Analogue Output Modules are configured and scaled using free T24 Toolkit software which runs on a PC connected to a T24 base station.
The T24-AO1 industrial version (T24-AO1i) is housed in an IP67 sealed enclosure and offers a digital input allows for zeroing of the incoming data value. This version also offers extended range over the desktop version.
The license free 2.4GHz direct sequence spread spectrum (DSSS) radio technology offers high integrity, error free communications which can co-exist with other wireless technologies such as Wi-Fi, Bluetooth® and Zigbee®. FCC, ETSI and IC approvals.
