E5CC-CX2ASM-800

Product information

Product Overview

An E5CC-800 series temperature controller with a linear current control output (4 to 20 mA / 0 to 20 mA) and two auxiliary outputs, on a 100 to 240 VAC supply. The current output is what lets the controller drive a power controller or valve positioner rather than switch a load directly.

This page is written for buyers and maintenance engineers sourcing E5CC-CX2ASM-800 as a new part or a replacement. Every specification below is taken from Omron’s own published data for this model; no third-party or estimated figures are used, and where Omron publishes two different figures or two variants for the same parameter, both are shown.

Omron catalogue designation: E5CC-800 series — 48 × 48 mm, linear current control output. Official catalogue code for this model: E5CC-CX2ASM-800.

Why Buyers Specify This Model

A current output is what a power controller expects

4 to 20 mA or 0 to 20 mA into a load of up to 500 Ω. Where the heating is controlled by a thyristor unit, a power controller or a valve positioner rather than switched on and off, this is the output type that talks to it directly — no converter, no relay, and the controller retains continuous authority over the setpoint.

Two auxiliary outputs, no communication — a deliberately simple configuration

Omron’s −800 lineup separates the options into distinct model numbers. This one has two auxiliary outputs for alarms but no RS-485 and no event inputs. If the machine needs the controller read by a PLC, the RS-485 variants in the same table (E5CC-CX2ASM-804 and the −802 codes) are the ones to look at. This model is the right answer only when the controller works standalone.

The −800 suffix is the region, and it is not cosmetic

Omron catalogues the E5CC with different model numbering per region: the “−000” series and the “−800” series are distinct catalogue entries with their own lineup tables. Both are official Omron products; they are not interchangeable model numbers, and a page that treats “−800” as decoration will get the order wrong. This page uses Omron’s own −800 lineup table.

Universal input removes a specification decision

The “M” input code means the controller accepts thermocouple, Pt100/JPt100 and analog current or voltage. In practice that means the same spare part covers a machine regardless of which sensor type each zone uses — which is the main reason to hold one model rather than three.

Read from Omron’s official E5CC-800 lineup table: the “CX” pair means control output 1 is linear current and there is no second control output; the “2” is the auxiliary output count; “A” is the 100–240 VAC supply; “S” is the screw-terminal body of the E5CC series and “M” is universal input. The sister codes are E5CC-QX2ASM-800 (voltage output for SSR drive) and E5CC-RX2ASM-800 (relay output).

Lifecycle and availability

E5CC-800 is an official Omron catalogue family with a published model lineup table, of which this model forms part. Omron’s E5CC platform is current and actively developed.

The −800 range is dense: control output, auxiliary output count, communication, heater burnout and event inputs each change the model number. Which means a near-miss is easy to supply by accident and hard to notice until commissioning. Send the full number from the label of the controller you are replacing, or the complete requirement, and we will match it against Omron’s official table before quoting.

Availability, condition of supply and lead time are quoted per enquiry because they depend on quantity and on where the goods are held. We do not publish stock or lead time as fixed figures on this page. Tell us the quantity and the date you need it and we will answer with a firm position rather than a promise.

Full technical detail — wiring diagrams, derating curves, installation requirements and the complete ordering tables — is in that document. If you need a specific figure we do not show here, ask and we will point you to the exact page rather than paraphrase it.

Ordering This Part

Send us the full catalogue number E5CC-CX2ASM-800 (and the model number E5CC-CX2ASM-800 you are replacing), the quantity, your delivery address and the date you need the goods. If it is a replacement, attach a photograph of the existing unit’s nameplate — it removes any doubt about the revision, the output type or the supply voltage, which are the three things that most often cause a wrong part to be shipped.

We do not publish stock, condition or lead time as fixed figures here, because they change: they are quoted per enquiry against the quantity and date you actually need. If a machine is down, say so and give us the required window — that is the information that determines how we source it.

Frequently Asked Questions

What is the difference between E5CC-CX2ASM-800 and E5CC-QX2ASM-800?

Only control output 1. CX is the linear current output (4–20 mA / 0–20 mA); QX is the voltage output for driving an SSR (12 VDC, 21 mA max.). Everything else — two auxiliary outputs, 100 to 240 VAC supply, universal input, 48 × 48 mm, screw terminals — is the same. Choose by what the controller has to drive.

Does this model have serial communication?

No. The official lineup table shows no communication method for this code. The RS-485 variants are E5CC-@X2ASM-802 (RS-485) and E5CC-CX2ASM-804 (RS-485 plus event inputs). If the PLC must read or write the setpoint, order one of those instead.

Is “−800” a different product from “−000”?

It is a different catalogue entry with its own model lineup, published by Omron for the China/Asia region. Both are official. Because the numbering differs between the two, we quote against the exact number you are replacing rather than translating between them.

Can I get the heater burnout option?

Not on this code — the official table marks heater burnout detection as not fitted. In the −800 lineup the heater burnout options sit on other model numbers (the −801 group). Tell us the full requirement and we will identify the correct number from Omron’s table.
