About product:
The AAR181-S00 S2 is an RTD Input Module designed to provide 16 outputs of 4-20 mA signals. This module supports dual-redundant configurations, which can be achieved by using two identical modules with the same suffix codes. When used in this configuration, it enhances system reliability and ensures continuous operation.
The module generates a voltage between the connecting terminals for 2-wire transmitters. When calculating the minimum operating voltage for the transmitters, it's important to account for voltage drop in the external wiring to ensure accurate operation.
Additionally, when the module is installed in an ER bus node unit with HART functionality, the EB401 firmware must be revision 2 or later for proper operation.
FAQ:
1. What is the main function of the AAR181-S00 S2 RTD Input Module?
The AAR181-S00 S2 module is designed to provide 16 outputs of 4-20 mA signals. It interfaces with RTD (Resistance Temperature Detectors) sensors to measure temperature and then transmits the corresponding 4-20 mA analog signals to the connected system.
2. Can the AAR181-S00 S2 be used in a redundant configuration?
Yes, the module supports dual-redundant configurations. By using two identical modules with the same suffix code (e.g., S00 or S2), you can achieve high availability and system reliability.
3. What is the operating voltage for the AAR181-S00 S2 module?
The module generates a voltage between the connecting terminals to support 2-wire transmitters. When calculating the minimum operating voltage, ensure that you account for voltage drops in the external wiring to maintain accurate readings.
