## **Product Descri tion p** 

DIC01 and PIC01 are precise TRMS AC/DC over+under, over+over or under+under current and voltage (selectable by DIPswitch) monitoring relays. DIC01 can perform also DC plus/minus measurement by short circuiting pins Z3 and Y1. The devices can be connected to the MI or MP and A82 or E83 current transformers. 

own time delay. Only for DIC01 each set level can work with a single SPDT relay. 

Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relays. 

Both relays have two individual set levels with their

**DIC01, PIC01** 

## **Mode of O eration p** 

DIC01 and PIC01 monitor both AC and DC current and voltage. DIC01 can also monitor positive and negative DC voltage connecting terminals Y1 and Z3. 

## **Example 1** 

(no contact input - under+over voltage - 2 x SPDT N.D. relays (1 x SPDT for PIC01) - TRMS) DIC01: One relay operates when the voltage drops below the under voltage set point for more than the respective delay time. It releases when the voltage exceeds the set level plus the set hysteresis. The other relay operates when the voltage exceeds the over voltage set point for more than the respective delay time. It releases when the voltage drops below the set level minus hysteresis. 

PIC01: The relay operates when the voltage drops below the under voltage set level for more than the respective set delay time or when it exceeds the over voltage set level for more than the relative set delay time. The relay releases when the voltage exceeds the under voltage set level plus hysteresis and it drops 

below the over voltage set level minus hysteresis (the hysteresis is the same for both set levels). 

## **Example 2** 

(latch enable active - under+under current - 2 x SPDT relays (1 x SPDT for PIC01) - TRMS) 

DIC01: Each relay operates and latches when the current drops below the respective set level for more than the respective delay time. Provided that the current has exceeded the respective set level plus hysteresis, each relay releases when the contact input’s connection is interrupted. 

PIC01: The relay operates when the current drops below the higher set level for more than the respective delay time. Provided that the current has exceeded the higher set level plus hysteresis the relay releases when the contact input’s connections is interrupted. 

## **Note** 

Different delay times can be used for appropriate reaction according to the set points. 

## **Example 3** 

(inhibit enable active - over+over current with MI CT - DPDT relay (SPDT for PIC01) - TRMS) 

Provided that the contact input’s connection is interrupted, the relay operates when the current flowing in the MI CT exceeds the lower set level for more than the respective delay time. It releases when the current drops below the lower set level minus hysteresis or when the contact input’s pins are connected. 

## **Example 4** 

(inhibit enable active - over+over current with A8210 CT - DPDT relay (1 x SPDT for PIC01) - TRMS Provided that the contact input’s connection is interrupted, the relay operates when the current flowing in the A82-10 CT exceeds  the lower set level for more than its delay time. It releases when the current drops below the lower set level minus hysteresis or when the contact input’s pins are connected. 

## **Example 5 (DIC01 only)** 

(no contact input - under+over voltage - 2 x SPDT N.D. relays - plus/minus DC 

One relay operates when the voltage drops below the under voltage set point for more than the respective delay time. It releases when the voltage exceeds the set level plus the set hysteresis. The other relay operates when the voltage exceeds the over voltage set point for more than the respective delay time. It releases when the voltage drops below the set level minus hysteresis. 

In this case the spare front label has to be placed on the device for proper level adjustment. 

## **Note** 

When the inhibit contact is opened, if the input signal is already in alarm position, the delay time needs to elapse before relay(s) activation.
