        Features:

        • Dual response modes: High-speed and low-overshoot PID behavior support different thermal-process priorities.
        • Flexible input platform: The controller accepts multiple sensor and analog input families when switches and parameters are configured correctly.
        • Documented legacy identity: The complete suffix preserves output and option details needed for migration from a discontinued controller.
        TZ4W-24S combines temperature indication, setpoint control and event handling in a wide panel format.

        Its exact model record distinguishes installed settings and terminal use that may differ from another unit with the same front dimensions.

        The product description owns functional identity; the FAQ owns migration, evidence-capture and terminal-boundary decisions.

        Apter Power can help document the Autonics TZ4W-24S Dual-Speed PID Temperature Controller with Protection Cover and review replacement interfaces before quotation.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Process requirement: Record the installed sensor, setpoint range, output action and event duties before selecting a successor.
        • Evidence package: Require an official specification and a complete panel drawing for any proposed successor.
        • Physical envelope: Compare front dimensions, depth and terminal clearance as separate mechanical checks.
        • Quotation scope: State whether the offer is unused stock, repaired stock or an engineered successor.
        • Power isolation: Disconnect supply and output circuits before moving conductors.
        • Terminal-by-terminal transfer: Label every wire and map it to the new controller; do not transfer by physical position.
        • Input configuration: Set the internal selection and software input type consistently before energizing the sensor circuit.
        • Controlled start-up: Restore one isolated circuit at a time under the approved machine procedure.
        • Fault separation: Check the sensor, SSR, wiring and process response before declaring the controller failed.
        • Terminal condition: Inspect looseness, heat damage and conductor identification before moving the unit.
        • Legacy preservation: Retain the removed controller and photographs until the replacement is accepted.
        • Migration file: Store the final old-to-new terminal map with the machine maintenance record.
        • Legacy heating machines: Maintains documented temperature control in established equipment.
        • Ovens and furnaces: Supports installations that use SSR switching and event contacts.
        • Process skids: Provides local setpoint and alarm functions where the existing panel design is retained.
        • Controlled migration: Serves as the reference identity for engineering a replacement controller.
        Description
        The selectable PID behavior of TZ4W-24S lets an integrator balance faster temperature response against overshoot control for the actual process. This turns the controller’s dual-speed design into a practical tuning choice rather than a fixed response pattern.

        As the wide-format TZ-series configuration, TZ4W-24S combines an SSR drive control output with two event outputs. The exact suffix identifies how the controller connects to the panel and surrounding control circuit.

        The two event outputs on TZ4W-24S allow panel logic to signal operating conditions separately from the primary heat-control command. Its supplied protection cover remains part of the complete wide-format assembly.
        Alternative Names

        Technical notes
        Isolate supply and output circuits before handling TZ4W-24S terminals. Label every conductor by terminal number, keep the legacy controller available as a reference and transfer no wire by physical position alone. Use the approved machine procedure to restore power in stages and record the final terminal map after commissioning.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        A supplier offers another 96 x 48 mm PID controller for TZ4W-24S. Is the matching cut-out enough to approve it?
        No. Confirm the installed sensor, SSR drive interface, two event functions, supply, terminal mapping and programmed control behavior. Mechanical fit is only one part of a safe migration.
        The plant has no parameter record for TZ4W-24S. What should maintenance capture before removal?
        Photograph the displays and wiring, record both input switches, step through all accessible parameters and document how each event output is used. Without that baseline, commissioning becomes an uncontrolled reconstruction.
        An installed TZ4W-24S shows an OPEN indication. Should the controller be replaced immediately?
        First inspect the sensor, compensation or RTD wiring, terminal tightness and configured input type. The indication can result from an open or mismatched input circuit rather than an internal controller failure.
        A replacement for TZ4W-24S drives the heater continuously after rewiring. Which comparison is critical?
        Verify output type and action, the SSR input requirements, heating-versus-cooling configuration and the transferred terminal map. Isolate the heater until the command can be proven safe with a controlled test.
        Purchasing found unused TZ4W-24S stock without a protection cover. Is it the same supply scope?
        The controller may share the electrical model, but the requested identity includes the protection cover. Require the quotation to state whether the cover is present and serviceable before accepting the scope.
        A replacement plan omits the Event 2 shutdown permissive used with TZ4W-24S. May commissioning continue?
        No. Record the original Event 2 setpoint, mode, terminal path and receiving circuit, then reproduce or formally redesign that function before energizing heat. Matching the temperature-control output alone does not restore the permissive logic.
