Honeywell RA889A1001 Switching Relay with internal transformer
The RA889A Switching Relay provides intermediate switching of line- and
low-voltage devices from a line or low voltage controller and is typically
applied in hydronic heating systems.
High load switching capability.
Replaceable transformer fuse.
Long-life DC relay drive control technology.
Relay for use with external 24 Vac or 24 Vdc supply, with line-voltage
control, or with internal 24V transformer supply.
One model replaces many Honeywell models
Perfect choice when converting from a 2-wire 750 mV system to a low voltage
conventional or WiFi thermostat
