Notes
• In the case of voltages above 30 VAC/DC and if inductive
components are to be connected to relays switching
more often than once every 2 minutes, these com-
ponents must be prevented from causing harmful
interference to radio or television reception (conformance
with EN 55014).
• Max. voltage for UL 864-compliant applications is 24 V.
Status LEDs with Manual Overrides
Fig. 75 Manual overrides (sliding switches)
The …R824 Relay Output Modules are equipped with
manual overrides: one for each relay output. These sliding
switches can manually be set to either "auto" or "0" or "1".
