E5CC-QX2ASM-800

Product information

Product Overview

An E5CC-800 series temperature controller with a voltage control output for driving an SSR and two auxiliary outputs, on a 100 to 240 VAC supply. This is the configuration for a panel where the heater is switched by a solid-state relay rather than a mechanical contactor.

This page is written for buyers and maintenance engineers sourcing E5CC-QX2ASM-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, SSR-driving voltage control output. Official catalogue code for this model: E5CC-QX2ASM-800.

Why Buyers Specify This Model

The voltage output is a control signal, not a load switch

12 VDC at up to 21 mA drives the input of a solid-state relay. It is deliberately not rated to switch a heater directly — the SSR does that. Getting this right matters: an SSR driver supplied where a relay output was needed leaves the panel with nothing to switch the load, and a relay output used to drive an SSR wears its contacts out through frequent switching.

SSR switching is why you would choose this over RX

Where a machine cycles a heater on and off frequently — fast packaging seal bars, small thermal zones, anything with a short cycle — mechanical relay contacts are the life-limiting component. Driving an SSR removes the moving part. The short-circuit protection circuit on the output is part of what makes that reliable.

Two auxiliary outputs, and the option codes that go with them

This code carries two auxiliary outputs and no RS-485 and no event inputs. Omron’s −800 lineup assigns the communication and heater-burnout options to separate model numbers. If the requirement includes reading the controller from a PLC or detecting a failed heater, this is not the code — the −802 and −801 groups in the same official table are.

Universal input, one spare for the whole machine

Thermocouple, Pt100/JPt100 and analog current or voltage on the same part number. On a multi-zone machine with a mixture of sensor types, that is one spare to hold instead of one per zone.

Read from Omron’s official E5CC-800 lineup table: the “QX” pair means control output 1 is the SSR-driving voltage output and there is no second control output; the “2” is the auxiliary output count; “A” is the 100–240 VAC supply. The sister codes are E5CC-CX2ASM-800 (linear current output) and E5CC-RX2ASM-800 (relay output).

Lifecycle and availability

E5CC-800 is an official Omron catalogue family carrying its own published model lineup table, and E5CC is a current platform in Omron’s temperature controller range. Nothing in the official data for this code carries a discontinuation notice.

Because the −800 numbering encodes output type, auxiliary output count, communication and options in a single string, the safest way to order is from the label of the existing controller or from a complete statement of the requirement. We match against Omron’s own table and tell you the number rather than assuming a near-equivalent will do.

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.

Ordering This Part

Send us the full catalogue number E5CC-QX2ASM-800 (and the model number E5CC-QX2ASM-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

Can this drive a heater directly?

No. The control output is a 12 VDC signal at up to 21 mA, intended for the input of an SSR. The SSR switches the heater. If you want the controller to switch the load itself, the relay-output version is E5CC-RX2ASM-800 in the same official lineup.

What SSR should I pair it with?

An SSR whose control input accepts 12 VDC and draws no more than 21 mA. Tell us the heater voltage, current and whether switching is single- or three-phase and we will quote the controller and the SSR together so the drive level is matched.

Is the switching continuous or on/off?

With 2-PID control and an SSR, the output is time-proportioning or continuous depending on the model’s output configuration — which for a 12 VDC SSR drive output means a fast duty cycle. That is what gives tight control on a short thermal cycle.

E5CC-QX2ASM-800 or E5CC-CX2ASM-800?

QX drives an SSR with a voltage signal. CX produces a 4–20 mA current loop for a power controller or valve positioner. Both are 48 × 48 mm, 100–240 VAC, two auxiliary outputs, universal input. The choice is entirely about what the output connects to.
