Telem-RTA-XA

RTA-XA is a new extended version of RTA-A.

RTA-XA is based on Voipac's i.MX25 Controller.

RTA-XA has 2 HW versions - ver.A (main) and ver.B (optional). Versions have different front panels.

Both have 32 LED's for main digital inputs status indication, one bi-color LED for device status indication and one acknowledge button.

Ver.B has six additional multi-purpose buttons with their status LED's.

Features

• Concentrated data acquisition and control using different communication protocols

5 serial ports: one RS232 full-modem port galvanically isolated, one RS232/485 (4-wire), one RS232, one RS232/GPS and one RS485 (2-wire) galvanically isolated port.

Ethernet

• Analog signal measurements

Six quasi-differential inputs with following HW factory configurable parameters:

1. Ground - real (power source low "-" level) for unipolar measurement or virtual (approx. +1.5V) for bipolar measurement.

2. ADC input range 0...3V.

3. Current measurement with shunt resistors 100 ohms (+-10 or 20 mA range) or 200 ohms (+-5 or 10 mA range).

4. Possibility to configure one input for voltage measurement (with restrictions).

Note: Not all HW configure possibilities have firmware and configuration SW support!

• Digital contact and acquisition of pulse counting info

32 main digital inputs + 2 additional (on the controller board), all optically isolated.

• On/Off control functions

8 x 2 digital outputs (dry contacts).

• "Execute" signal output (dry contact)
• Time synchronization using GPS
• Analog outputs for control (optional)

2 outputs 4...20 mA

• IFR output (dry contact)
• Power input from 10 to 72Vdc
• Temperature sensor (1-wire) input.
