Comparison with Similar Modules
-
Compared with standard TDC 3000 output modules, the 621‑2201R provides full electrical isolation for all channels, minimizing the risk of cross-channel faults.
-
Modules without isolation may be less expensive but require additional external safety relays.
FAQ
Q: Can this module switch inductive loads like motors?
A: Yes, the module is rated for AC inductive loads, but ensure the connected load does not exceed the maximum amperage per channel.
Q: Is this compatible with other Honeywell DCS systems?
A: The 621‑2201R is specifically designed for the TDC 3000 series and may not operate reliably in other Honeywell platforms.
