More Information

Overview Manuals Applications Protection Configuration & Programming Installation & Integration

Features:

  • Four independent relay switching points support separate temperature control decisions.
  • A four-digit red LED display provides local temperature and status indication.
  • A selectable analog output supports integration with PLC and monitoring systems.
The current configuration is the ETS 1701 display version with a 0 to 100 °C measuring range and standard modification code 000.

The electronic controller is intended to process a PT 100 signal and operate relay-based heating, cooling, or alarm functions in hydraulic equipment.

Before installation, verify the separate probe type, terminal arrangement, relay grouping, supply voltage, and required analog signal format.

Availability: Configuration and condition should be confirmed before ordering.

  • Hydraulic heating-process control for maintaining the required fluid temperature during machine operation.
  • Hydraulic cooling-process control for supervising temperature reduction and protecting hydraulic equipment.
  • Temperature monitoring through PLC-based systems for reliable process feedback and control decisions.
  • The controller stores the maximum temperature reached since power-up or the last reset.
  • Display filtering can be selected to provide slower, medium, or faster indication behavior.
  • Reverse-polarity, overvoltage, override, and short-circuit protection are provided.
  • Relay switch-on and switch-off delays can be configured independently within the controller.
  • Each relay can be set for normally open or normally closed switching direction.
  • Programming disable prevents unauthorized changes after commissioning.
  • The separate temperature probe connects through the specified five-pole Binder interface.
  • The 14-pole plug-in terminal block provides the electrical connection for supply and outputs.
  • The analog output can be connected to a PLC or supervisory monitoring input.
Description
HYDAC ETS 1701-100-000 is an electronic temperature switch designed for use with a separate PT 100 temperature probe. The four-digit red LED display can show the measured temperature, configured switching values, or the stored maximum value.

The unit provides four independently adjustable relay switching points and switch-back points for controlling heating, cooling, and temperature-limit functions in hydraulic systems. A selectable 4–20 mA or 0–10 V analog output supports connection to supervisory systems and PLC-based monitoring equipment.

The ETS 1701-100-000 includes keypad-based configuration functions such as relay direction, switching delays, display filtering, unit selection, and programming lockout. Installation must account for the separate TFP 100 probe, relay wiring groups, supply polarity, and the electrical load connected to each output.

Technical notes
ETS 1701-100-000 requires a separately connected PT 100 temperature probe; the TFP 100 sensor is not the same item as the electronic switch.Relay direction, delays, display behavior, and programming lockout should be verified before commissioning because they directly affect the control sequence.

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.
Is the temperature probe included with HYDAC ETS 1701-100-000?
The probe is a separate component and must be verified as a separate line item.
Which sensor is used with HYDAC ETS 1701-100-000?
The controller is designed for a PT 100 sensor, typically the HYDAC TFP 100 family.
The probe is a separate component and must be verified as a separate line item.
Yes. The switch-back points or switch-back hysteresis can be configured independently for the relay channels.
Does the controller support delay functions?
Yes. Separate switch-on and switch-off delay settings are available for the relay channels.
Is HYDAC ETS 1701-100-000 suitable for hydraulic equipment?
Yes. HYDAC identifies the ETS 1700 family for temperature control and monitoring in hydraulic systems.
What should be checked when replacing an existing ETS 1700 unit?
Confirm the complete model code, sensor connection, measuring range, relay wiring, analog output, and supply voltage before replacement.
