E5CZ-Q2MT

Product information

Product Overview

A 48 × 48 mm digital temperature controller with voltage output for driving an SSR, two alarm outputs and a 100 to 240 VAC supply. The “T” in the model number identifies the terminal-block version of the E5CZ-Q2M.

This page is written for buyers and maintenance engineers sourcing E5CZ-Q2MT 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: E5CZ digital temperature controller, 48 × 48 mm. Official catalogue code for this model: E5CZ-Q2MT.

Why Buyers Specify This Model

Q2 is the SSR-driving output — check what it connects to

The control output is a 12 VDC signal at up to 21 mA, intended for the input of a solid-state relay. It does not switch a heater directly. On a machine where the heater is cycled frequently, an SSR removes the mechanical contact that would otherwise be the first thing to fail — which is exactly why this output type exists.

Two alarm outputs, and what they are rated for

Two SPST-NO alarm outputs at 250 VAC, 1 A. That is enough to drive a panel lamp, a buzzer or a PLC input directly, and the 1 A rating is the figure to hold against the load — alarm outputs are frequently overloaded by assuming they can carry the same current as the main control contact.

The “T” suffix is the difference between two real part numbers

Omron’s own legend lists E5CZ-Q2M as the previous model and E5CZ-Q2MT as the current one. That is not a cosmetic revision — the two are separate entries in the official catalogue, and ordering the wrong one on a replacement job is the kind of error that only shows up when the controller does not fit or does not match the panel cutout drawing.

48 × 48 with a 78 mm body and dual display

Dual PV/SV indication with an 11 mm PV character height in a 1/16 DIN body. In a multi-zone panel that is the practical combination: the panel cutout is standard, and the operator can read the process value and setpoint together without cycling displays.

Read directly from Omron’s official E5CZ model number legend: “Q2” is the voltage output for driving SSR with two alarm outputs, “M” indicates the no-option-unit mounting, and the trailing “T” is what distinguishes this from the predecessor E5CZ-Q2M. The relay-output equivalent in the same table is E5CZ-R2MT.

Lifecycle and availability

E5CZ is documented in Omron’s own catalogue (Cat. No. H209-E1-03) covering E5AZ, E5CZ and E5EZ, with the model number legend, ratings, characteristics and dimensions reproduced on this page.

This is an established controller family that Omron’s newer E5CC/E5CD generation sits alongside. For machines already using E5CZ, matching the existing model number is normally the right answer — panel cutout, wiring and parameter set are then unchanged. For new builds, the E5CC is worth pricing alongside. Either way, give us the label details of the existing unit and we will confirm the exact number.

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 E5CZ-Q2MT (and the model number E5CZ-Q2MT 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

E5CZ-Q2MT or E5CZ-R2MT?

Q2 is the voltage output for driving an SSR; R2 is a relay output that switches a load directly. Both carry two alarm outputs, both are 100–240 VAC, both are 48 × 48 mm. Choose based on whether an SSR is in the circuit or the controller switches the load itself.

What is the difference from E5CZ-Q2M?

Omron’s model number legend lists E5CZ-Q2M as the previous model and E5CZ-Q2MT as the replacement. Match against the label on the controller being replaced — that is the only reliable way to confirm which one your installation uses.

Can I use it with a Pt100 sensor?

Yes. The temperature-input models accept thermocouple types K, J, T, E, L, U, N, R, S and B, or Pt100 / JPt100, plus the ES1B infrared sensor. Irrespective of sensor type it is the same part number, because the input is not fixed at order time on these models.

Does it have serial communication?

The E5CZ family has separate communications models (Communications Manual Cat. No. H208 covers them), and there is a family of models with communications functions. This code is not one of them. If the PLC must read the controller, tell us and we will identify the communications variant.
