Elimko E-72P Series Universal Advanced Digital Controllers - Quick Start Guide

1. Description

The E-72P Series are universal process controllers, designed as industrial devices with 72x72 mm IEC/TR 60668 dimensions. They utilize new-generation microcontrollers and support on/off, PID, and other control forms, with user-programmable inputs and outputs. The controllers feature two 4-digit displays capable of showing set and measured values from -1999 to 9999. General-purpose inputs (T/C, R/T, mV, mA) can be programmed.

2. Dimensions and Panel Cut-Out

Physical Dimensions: 72 mm (Length) x 72 mm (Height) x 100 mm (Width).

Panel Cut-Out: 68 mm (Length) x 68 mm (Height).

Minimum spacing required: 10 mm front, 35 mm rear.

3. Connection Diagram

Description of terminal connections:

• Power Supply: Terminals 5, 6, 7.
• Relay Outputs: RL1 (Terminal 1), RL2 (Terminal 2).
• SSR Outputs: SSR1 (Terminal 3), SSR2 (Terminal 4).
• Communication: RS-485 (Terminals 8, 9: GND, TRX+, TRX-).
• Analog Outputs: AO1 (Terminal 10), AO2 (Terminal 11).
• Analog Inputs: Terminals 12-21 for various input types (Thermocouple, Resistance Thermometer, Current, Voltage).

Note: 1st and 2nd control outputs can be selected as Relay (RL1, RL2) or SSR (SSR1, SSR2). Analog output (AO1, AO2) can be selected as mA or 0-10 V DC.

4. Warnings

• E-72P controller is designed for panel mounting and should be used in an industrial environment.
• The package of E-72P controller contains: Controller, 2 pieces of mounting clamps, User manual and Guarantee certificate.
• Before installing and operating the controller, please read the user manual thoroughly.
• The installation and configuration of the controller must only be performed by a person qualified in instrumentation.
• Keep the unit away from flammable gases, that could cause explosion.
• Do not use alcohol or other solvents to clean the controller. Use a clean cloth soaked in water tightly squeezed to gently wipe the outer surface of the controller.
• It is not used in medical applications.

EU Directive Compliance: Low Voltage Directive EN 61010-1, EMC Directive EN 61326-1.

5. Type Coding

The E-72P Series model number is structured as: E-72P - W - X - Y - Z

• W (Relay Outputs): None, 1 relay (RL1), 2 relays (RL1, RL2), 1 SSR (SSR1), 1 SSR (SSR1) + 1 relay (RL2), 2 SSR (SSR1, SSR2).
• X (Analog Outputs): None, 1x 0-20/4-20 mA (AO1), 2x 0-20/4-20 mA (AO1, AO2), 1x 0-10 V DC (AO1), 2x 0-10 V DC (AO1, AO2), 1x 0-20/4-20 mA (AO1) + 1x 0-10 V DC (AO2).
• Y (Communication): None, RS-485.
• Z (Operating Voltage): 85-265 V AC / 85-375 V DC, 20-60 V AC / 20-60 V DC.

* Analog outputs are isolated from each other.

** When E-72P Series devices are ordered with communication, the E-IB-11 USB-RS485 converter can be used for PC connection. There are various control and monitoring software provided by Elimko.
