Pre-assembled Device with P.I.D. or ON/OFF Temperature Control
Compact temperature control device with safety shutdown for versatile use, both in simple ON/OFF operation and for controlling a complex P.I.D. control loop. Pre-assembled in a compact desktop housing with dimensions approx. 137x80x180 mm (W x H x D). The controller is connected to a properly secured household Schuko socket. The consumer to be controlled is plugged into the device socket at the back of the controller housing (plug included).
The temperature controller is designed for connecting PT100 sensors or various thermocouples. Please choose the sensor suitable for your application and temperature range from the "Individual Accessories" offered for this device or from our standard program! If you order a matching sensor at the same time, we will mount and configure it on the device.
Alternatively, versions with housing sockets for different temperature sensors are available.
The control of the load to be regulated is done via an integrated SSR relay with a generously sized rated load of 25A / 230VAC (max. switching load = 10A for resistive load). A standard glass fuse size 5x20mm (at the front) provides protection for the control unit. The protection of the connected load is ensured by the external fuse of your home installation. After plugging in, the controller is turned on via a front ON/OFF switch. Operation is entirely through the membrane keypad of the control unit.
Any alarm temperature can be preset, which leads to an emergency shutdown via an integrated load relay, disconnecting the load from the mains in all poles. Re-activating after an emergency shutdown is only possible manually via the "START - Reset" button once the temperature has cooled to the normal value.
To adapt to your control task, the controller offers a variety of special functions that can be selected via easily accessible parameterization:
-
ON/OFF operating mode with freely selectable hysteresis 0...50°C (acting on both sides)
-
Alternatively, P.I.D. control loop with autotuning function
-
Password-protected parameterization (if needed)
-
Limitation of the maximum possible set temperature to prevent misoperation
-
Calibration function to eliminate sensor deviations
-
Shutdown of the load in case of sensor break or short circuit with error message display
-
Optional heating or cooling operation
The control range of the device is 0...1750°C, depending on the sensor used, with a resolution of 1/10°C, or exact degree resolution for measurement ranges >999°C. The actual measurement range depends on the sensor used. Please choose a sensor appropriate for your application from "Individual Accessories" or from our delivery program.
Technical Data
-
Housing: Ventilated two-part aluminum housing with a stainless steel look. Housing dimensions without attachments approx. 137x100x180mm (W x H x D). Four feet provide about 10mm of ground clearance. Ventilation slots milled into the base and side walls ensure sufficient air circulation inside. Due to its design, this temperature controller is only suitable for use in dry rooms.
-
Control Unit: A-senco TR-81 built-in controller with integrated membrane keyboard. Can be parameterized as an ON/OFF controller or for comfortable P.I.D. control loops. With a two-line display and status LED indicators for active output and autotuning mode. Via menu function, selectable for heating operation or optionally for cooling operation.
-
Various useful additional functions like limiting the set temperature, calibration function for compensating measurement tolerances (not legal for trade), automatic shutdown in case of sensor break or short with error message, optional password protection, etc., recommend this temperature control for many applications.
-
Temperature Range: Controller measurement range: -199...+1750°C with 1/10 degree accuracy resolution, or exact degree for ranges >999.9°C. The internal measurement resolution is always 1/10 degree Celsius. Sensor not included in the price. If you order a sensor suitable for your application at the same time, it will be mounted and configured on the device without additional charge.
-
Load Relay: SSR semiconductor relay. Rated load 25A 230VAC, with zero-crossing switching. Control voltage 3-32VDC including LED indication when the load is active. Maximum switching load of the controller: 10A at 230VAC resistive load (for inductive loads, the switching load must be adjusted accordingly).
-
Load Connection: The controller is designed for switching a load at 230VAC, max. 10A (AC1). Inductive loads must be fitted with appropriate suppression according to the requirements of SSR semiconductor relays.
-
Fuses: 1x glass fuse (front) size 5x20mm 250mA, fast-acting for protecting the control voltage of the control unit. The load is protected externally via a 10A thermal circuit breaker (230VAC).
-
Connections: The load is switched through a rear-mounted cold device socket C13, with plug C14 according to IEC-60320 standard. Two cable glands introduce the main supply line included in the scope of delivery (rubber cable H07RN-F 3G1.0 or similar) for power supply (230VAC), and another M12 cable entry (max. cable diameter approx. 6mm) for introducing the measurement line (e.g., temperature sensor).
-
Accessories: Delivered plug-ready and operational if a sensor is ordered simultaneously. Including wiring diagram and German CE-compliant operating instructions for the entire device and the included built-in controller.

Intended Use
Other Information
-
The controller is delivered with a protective foil on the housing, which must be removed before commissioning. Max. ambient temperature 45°C. Max. allowable humidity: 85% in a non-aggressive environment (e.g., do not place near acid-containing batteries).
