em4 Accessories Digital expansions

Product catalog summary

Digital Expansions:
Up to two digital/analog expansions can be added to the em4 nanoPLC, expanding up to 46 I/Os. It includes 6 configurable digital/analog inputs (0-10 VDC, 0-28.8 VDC, Potentiometer) for NTC temperature sensors or LDR light sensors without additional converters. There are 4 relay outputs (2x 6A/250VAC & 2x 8A/250VAC) for controlling power actuators like valves and pumps.

Specific Characteristics:
Part number: 88 982 113, Type: E10R. It features 6 digital inputs configurable as analog, and 4 relay outputs. The supply is 24 VDC powered by the controller. The finish is glossy black with a black RAL 9011 front panel and blue RAL 5017 terminal block. Protection rating is IP 40 on the front panel and IP 20 on the terminal block. Weight is 130 g without packing and 170 g with packing. Dimensions are 60.4 x 90 x 60.6 mm without packing and 93 x 103 x 65 mm with packing.

General Characteristics:
Certified with CE, cULus Listed, and conforms to IEC/EN 61131-2, IEC/EN 61000-6-1, 61000-6-2, 61000-6-3, and 61000-6-4. It has no earthing, overvoltage category 3, and pollution degree 2. Maximum utilization altitude is 2000 m for operation and 3000 m for transport. It is resistant to vibrations, shock, electrostatic discharge, HF interference, and has conducted and radiated emissions class B. Operating temperature is -20°C to +60°C, and storage temperature is -40°C to +80°C. Relative humidity is 95% max.

Inputs:
Digital 24 VDC and analog inputs are 12 bit/28.8 V with 6 inputs from I1 to I6. Input voltage is 24 VDC with a current of 1.8 mA at 20.4 V, 2.1 mA at 24 V, and 2.5 mA at 28.8 V. Input impedance is 11.6 kΩ. Logic 1 voltage threshold is 11 VDC, and logic 0 is 9 VDC. Response time is 1 to 2 cycle times. Input type is resistive with no isolation between power supply and inputs.

Outputs:
6A relay outputs (O1 to O2) have a breaking voltage of 250 VAC max and a breaking current of 6 A. Mechanical life is 5,000,000 operations. 8A relay outputs (O3 to O4) have a breaking voltage of 250 VAC max and a breaking current of 8 A. Mechanical life is 20,000,000 operations. Both have built-in protections against short-circuits and over voltages.

Diagrams and Connections:
Includes detailed diagrams for dimensions and connections for inputs and outputs, specifying cable lengths and configurations for PNP and relay outputs.
