FAQ
Q1: Can this module replace an older TDC 2000 CPU directly?
A1: Yes. The 620‑0636 is fully compatible with TDC 2000 backplane and I/O architecture and can be used as a direct replacement.
Q2: How many I/O channels does it support?
A2: The module communicates with all digital and analog I/O modules connected via the backplane. The total number of I/O channels depends on the system configuration.
Q3: Does it have battery-backed memory?
A3: Yes. It uses battery-backed SRAM or EEPROM to retain configuration data even during power loss.
Q4: Can it operate in high-temperature environments?
A4: The module operates within 0–60°C and can be stored at −20–85°C, suitable for most industrial applications. Avoid exceeding operating limits.
