Remote Relay Connection - Macurco DVP-1200 Manual

Macurco TM DVP-1200 Manual
between the power supply and the MRS-485 should not be an issue if the recommended power wire gauge guidelines are
followed.
The terminals will accept wire from 16 to 28 AWG. To install a wire, strip back approximately 0.25 in. (6 mm) of insulation and
insert the bare wire into the terminal. Tighten the screw clamp and ensure that the wire cannot be easily pulled from the
connector.
3.2.4.12 4-20mA Connection
There are three 4-20mA output modular connectors. The wire terminals for the three 4-20 mA connectors are available at the
connector labeled "4-20mA O/P". The connector accepts wires from 16 to 28 AWG. Refer to Figure 3-4 for details.
3.2.4.13 Relay Connection
The wire terminals for the four onboard relays are available at the connectors labeled "R1", "R2", "R3", and "R4". The wire
terminals for the optional expansion relays are available at the connectors labeled "R5", "R6", "R7", and "R8".
Each relay will be wired to be either normally open (NO) or normally closed (NC). There is no polarity for these connections.
Each terminal can accommodate a wire size from 12 to 24 AWG.
Connect one wire to the COM terminal. For normally open (NO) configuration, connect the other wire to the NO terminal. For
normally closed (NC) configuration, connect the other wire to the NC terminal.
To connect wires to the relay terminals,
1. Strip each wire back 1/4 in. (6.5 mm).
2. Press down the white button of the connector.
3. Insert the bare wire into the wire cavity of the connector.
4. Release the white button.
5. Ensure that the wire cannot be easily pulled from the connector.

3.2.5 Remote Relay Connection

In addition to the onboard relays (four standard and four optional), the DVP-1200 can be connected to two additional remote
relays. Each remote relay box includes two relays.
The wire terminals for the Remote Relay are available at the connector labeled "REMOTE RELAY CONNECTION".
Remote Relay (RR-24) Mounting:
Macurco RR-24 is shipped with mounting brackets and screws. Install mounting brackets on the back four corner of the
enclosure. RR-24 should be mounted with sufficient space all round for access to conduit entry holes provide on the top and
bottom side of the unit.
Remote Relay (RR-24) Wiring
All the connectors in RR-24 are spring tightening and will accept wire from 14 to 24 AWG. To connect the wires to terminals,
press down the white button of the connector (use flat-headed screwdriver), insert bare wire into respective wire cavity of the
connector and release the white button. Ensure that the wire cannot be easily pulled from the connector. Refer to figure below
for location of different connectors in RR-24.
The power connections to the RR-24 should be size AWG18 (minimum) for short runs. For longer run follow recommended
power wire gauge guidelines. Match the polarity for power connection.
