Simple Operation & Advanced Features

Programmable Alarm Annunciator with 36 Digital Inputs, 36 potential contacts in the field are activated by connecting them to the device input ends.
Each digital input can be assigned to the HORN auxiliary relay with a red LED or BELL (BELL) with a green LED, depending on the operator’s preference. In the BELL auxiliary relay assignment, the corresponding channel is illuminated in GREEN, and in the HORN assignment, it is illuminated in RED. (Optional Red/Amber color option available)

RS-485 Communication Port (optional)

It supports Modbus RTU protocol with galvanic isolation protection and RS485 serial communication port integrated into the device. In this way, it can be easily integrated into SCADA systems. Instant status information for each digital input can be read and written remotely.
Horn, Test, Ack and Reset keys can be controlled remotely via SCADA or other systems.

Rapid Commissioning

With the push buttons positioned on the front panel, auxiliary relay ( Red LED HornGreen Led Buzzer ) selections for each input can be made independently of software, without the need for a Dip Switch. Thanks to this special design, settings can be made safely in an energized state without touching the panel. For a detailed explanation, you can read our article titled How to Make Quick Configuration in Telepro Annunciators

Advanced Configuration Software (Optional)

(*) Note: You can download ISPsimTM software here

With ISPsim™(*) software; relay selection (Horn – Bell), response and release times and ModbusID settings can be performed.
ISA18.1 Sequence Code M (Manual RESET) code is provided as standard.

Digital Inputs

All Inputs are opto coupler insulated, varistor protected, common return end and filtered. It fully complies with EU Electromagnetic Qualification (EMC) and Low Voltage Regulation (LVD) requirements. The possibility of false alarms is completely eliminated.
Input voltages can be ordered as 24/48Vdc, 110/220Vdc and 220Vac as options.

Auxiliary Relay Outputs

One of the most important parts of Alarm Annunciators is the auxiliary relay outputs. High-quality SCHRACK relays are always used to avoid any malfunctions or errors.
The TELEPRO ISP-36 Digital Input Programmable Alarm Annunciator has two Normally Open 1-FormA type dry contact relay outputs as standard.
In addition, there is an orptional FAULT and WATCHDOG relay with common end Form C Type NC / NO outputs that are activated in case of internal system failures.

Adjustable Response and Release Times (Optional)

Adjustable response-release times can be adjusted between 3ms and 250ms with software control, offering flexible and reliable operation against magnetic fields that may occur during maneuvers.
The factory response time is 5ms, the release time is 20ms.

Why Are Response and Release Times Important?

High-Quality Power Unit

One of the most important parts of an Alarm Annunciator is the Power Supply
In the Programmable Alarm Annunciator with 36 Digital Inputs, Mean Well brand power modules specially designed for industrial control and electrical energy are used. In this way, our products have 3000VAC input and output isolation as well as short circuit, overcurrent/voltage and temperature protection.
This guarantees a long life and safe use of the Alarm Annunciator with 36 digital inputs.

Dashboard & Tagging

All LEDs are masked on the high-quality, membrane-enabled front panel, designed to be seen even in high-light environments.
Our easy-to-change printer-printed labeling system has a user-friendly design with a width of 51.5×11 mm allocated for each channel.
The windows of each entry are named with the label template provided by TELEPRO® in the computer environment. Label information can be easily changed at any time. The tagging template is available in the documentation.

Indicator LEDs

Insulated, ultra-bright 5mm energy-saving LEDs are used for each input. This provides excellent visibility for operators, even in high light.

Case & Mounting

The TELEPRO-ISP36 has a 288x144x82.5mm panel case. The protection class on the front panel side of our standard cases is IP51 and it can be assembled/disassembled quickly and safely with an easy-to-use screw mounting system weighing 1,310 gr.
