Relay Output Connection - Gicam RQ Installations- Und Bedieningsanleitung

Logic inputs connection
The logic inputs are electrically isolated from the instrument by opto-isolators.
 The logic input connection cables must not be channeled with power or power supply
cables.
 Use a connection cable that is as short as possible.
To activate a logic input, it must be brought to the positive of a 24 V DC power supply while the common
must be connected to the negative of the same.
The following diagram shows connections using, for example, a button on input 1 and a switch on input 2.

Relay output connection

The two outputs are relays with a single common. The capacity of each contact is 24 VDC / VAC, 1A.
Serial RS485 connection
 To make the serial connection use a shielded cable, taking care to connect the shield
to one of the two ends: to pin 13 if connected on the instrument side, to ground if con-
nected on the opposite side
 If the cable has a greater number of conductors than those used, connect the free
conductors to the shield.
 The cable must not be channeled with other cables (e.g. outputs connected to remote
control switches or power cables), but must possibly follow its own path.
