Technical FAQ
Does the AER4D-00 support 4-wire RTD sensors?
Standard design is optimized for 3-wire RTDs. For 4-wire applications, consult wiring schematics for compatible cross-terminal arrangements.
What does the “-00” suffix indicate?
It represents the base hardware revision without integrated surge absorbers, suitable for standard control room installations prioritizing cost and space efficiency.
Can this board be used for thermocouples?
No. The AER4D-00 is specific to RTDs. Thermocouple inputs require a dedicated terminal board such as AED5D, which includes cold-junction compensation.
