It runs on 100 to 240 VAC, 50/60 Hz — the same supply you'd feed a panel transformer — so it doesn't need a separate 24 VDC power supply in a standard control cabinet. The screw-terminal blocks on both the main unit and terminal unit make field wiring straightforward with ring or fork terminals; no special tools beyond a screwdriver. ## What the options and outputs mean for a control loop The '802' option code means this unit includes communications capability plus one current transformer (CT) input — the CT lets you monitor heater current directly, so the controller can detect a blown heater or open load without an external sensor. The single relay output (RX code) switches loads up to the contact rating — typical for driving a solid-state relay or a small contactor in a temperature control loop. Two auxiliary outputs (code '2') give you additional discrete signals — alarm outputs, event inputs, or retransmission of the process value — without adding an expansion module. The 'M' sensor input accepts thermocouples or RTDs, covering the common temperature ranges for industrial process control.","metaTitle":"Omron E5DC-RX2ASM-802 Digital Temperature Controller","metaDescription":"Omron E5DC-RX2ASM-802 digital temperature controller with relay output, 100-240 VAC supply, communications & 1 CT option.
