Function:
The IUC-X9-TXC is a telephone line transmitter which takes in one of a number of standard analog signals and two dry contacts. It has a 600 Ohm impedance matched output which can connect directly into a class C telephone line. A frequency signal is sent to the IUC-7X-RXC telephone line receiver where it is converted back to an analog signal and two "C" Contacts. The IUC-7X-RXC also has an impedance matched input to allow direct connection to the phone line. A built in line monitor detects line failures and ramps the analog output to 0% or 100%.

Specifications: Isolation: Input to Output to Power 1500 VAC (test) Accuracy/Linearity: 0.3% max., 0.1% typ. (@ 20-100% Output) Operating Temperature: -40 Deg.C. to +50 Deg.C Temperature Effects: 0.5% max., 0.2% typ. (for 40 Deg.C. change) Loop Drive: Max. 1000 Ohms at 20mA
