Installation & Compatibility
The 1734-IE2C mounts on standard DIN rail. It requires a terminal base (1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS). Set the keyswitch to position 3. It works with CompactLogix and ControlLogix controllers.
Frequently Asked Questions
- Q1: What sensors can I connect to this module?
A1: You can connect any 4-20mA or 0-20mA current output sensor, like pressure transmitters, temperature sensors, or flow meters. - Q2: What is the difference between 4-20mA and 0-20mA signals?
A2: A 4-20mA signal uses 4mA as the “live zero,” which helps distinguish a true zero reading from a broken wire. 0-20mA does not have this feature. - Q3: How do I configure the input filtering?
A3: The filtering (Notch frequency) is configurable in the module’s properties in Studio 5000. This lets you choose between faster response (500Hz) or better noise rejection (50/60Hz). - Q4: Can I use one channel for 4-20mA and the other for 0-20mA?
A4: Yes, each of the two channels on the 1734-IE2C can be independently configured for either signal range. - Q5: Is this module isolated?
A5: No, the 1734-IE2C is a non-isolated module. For applications requiring isolation, consider using external signal isolators.
