100% New and Original Switzerland Carlo Gavazzi Process Signal Relay Dic01dd48AV0

DIC01 and PIC01 are precise TRMS AC/DC over+under, over+over or under+under current and voltage (select able by DIP switch) monitoring relays. DIC01 can perform also DC plus/minus measurement by short circuiting pins Z3 and Y1. The devices can be con nected to the MI or MP and A82 or E83 current trans formers. Both relays have two indi vidual set levels with their 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.

• TRMS AC/DC over + under, over+over, under+under current and voltage monitoring relays
• DC process signal plus/minus monitoring relay (DIC01)
• Selection of measuring range by DIP-switches
• Adjustable current and voltage on relative scale
• Adjustable hysteresis on relative scale
• Separately adjustable delay functions (0.1 to 30 s)
• Programmable latching or inhibit at set level
• Output: 1 or 2 x 8 A SPDT relay N.D. or N.E. selectable
• For mounting on DIN-rail in accordance with DIN/EN/EC 60715 (DIC01) or plug-in module (PIC01)
• 45 mm Euronorm housing (DIC01) or 36 mm plug-in module (PIC01)
• LED indication for relay(s), alarm and power supply ON
• Galvanically separated power supply

DIC01 and PIC01 monitor both AC and DC current and voltage. DIC01 can also monitor positive and nega tive 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 oper ates and latches when the current drops below the respective set level for more than the re spective delay time. Provided that the current has exceeded the respective set level plus hys teresis, 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 hyster esis the relay releases when the contact input's connec tions is interrupted.

Note:
Different delay times can be used for appropriate reac tion according to the set points.
