Product Overview
The Omron E5CC-RX2ASM-802 is the 48x48 mm (1/16 DIN) PID temperature controller in the E5CC lineup. manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The face is 48 x 48 mm with a 15.2 mm-tall white PV display, four front buttons, and an IP66 panel seal; the body is 60 mm deep and fits the standard 45 x 45 mm panel cutout. The bare R suffix means a single SPDT relay control output -- this is the SKU for ON/OFF or PID switching of a contactor, SSR, or alarm horn, NOT a linear 4-20 mA valve actuator.
The E5CC-RX2ASM-802 ships from Xiamen with full datasheet documentation. Add the E58-CIFQ1 USB-serial conversion cable for CX-Thermo programming from a PC.
Key Features
- E5CC-series 48x48 mm (1/16 DIN) digital PID temperature controller
- AC 100-240 V supply at 5.2 VA (D suffix is the 24 V sibling)
- 50 ms high-speed sampling, 15.2 mm-tall white PV LCD display, +/- 0.3 % FS accuracy at 25 C
- ON/OFF or 2-PID control with auto-tuning
- SKU: E5CC-RX2ASM-802
- Series: E5CC-RX2ASM-802
- Voltage: 100-240 V
Best-Fit Applications
- Oven / furnace temperature control with alarm and event-based setpoint switching
- Heater-band temperature control on plastic-extrusion dies with SSR drive via the aux output
- Day / night setpoint switching on a climate chamber via the event input
Buying Checklist
- Pick E5CC-CX2ASM-802 instead when the load is a 4-20 mA proportional valve or phase-angle thyristor.
- Pick E5EC-PR2ASM-804 when the panel cutout is 48 x 96 mm, and E5AC-CX3ASM-804 for 96 x 96 mm.
- Pick E5CC-RX2DSM-802 for AC/DC 24 V cabinet supply (the D suffix swaps the 100-240 V supply for 24 V).

FAQ for E5CC-RX2ASM-802
What is the difference between the E5CC, E5EC, and E5AC?
Body size. E5CC is 48 x 48 mm (1/16 DIN) and the most common pick. E5EC is 48 x 96 mm (1/8 DIN) for taller cabinets with a larger display. E5AC is 96 x 96 mm (1/4 DIN) for big process panels. All three share the same PID algorithm, the same RS-485 CompoWay/F protocol on the -800 / -802 / -804 suffix SKUs, and the same CX-Thermo configuration tool. The electronic specs are identical -- the only difference is the front face and the depth.
What does the -802 suffix add over the bare E5CC-RX2ASM-000?
Three things. RS-485 CompoWay/F serial for SCADA / PLC polling. Two event inputs for external RUN/STOP, auto/manual, or setpoint switching. One heater-burnout CT input for 1-phase heater or SSR failure detection. The bare -000 has none of these. The intermediate -801 adds comm only; the -802 is the full set.
Can the relay output drive a 4-20 mA proportional valve?
No. The R suffix means SPDT relay dry contact -- it switches ON or OFF, it does not output a linear 4-20 mA signal. For a proportional valve, step up to the E5CC-CX2ASM-802 (current 4-20 mA output) or the E5CC-CX2ASM-804. For a fast-cycling SSR with a DC logic input, the E5CC-QX2ASM-802 (voltage output for SSR drive) is the faster pick -- the relay's 100,000-operation mechanical life is the limit on cycle speed.
Does the controller need a separate 24 VDC supply for the event inputs?
No. The E5CC powers the event inputs from its own internal supply -- dry-contact or PNP signals from the field land directly on the event-input terminals. The CT input likewise is a passive current transformer input -- the controller reads the AC current through the heater wire without needing a separate 24 VDC rail.
