5.3 Connection points

There are a number of connection points on the UP-2210-R for connecting to the measured object

and for communication links. The connections are described below:

Figure 25

A. Digital outputs. The digital outputs are relays, which can be used for alarms and for

controlling other equipment. The recorder can also be programmed to activate the digital

outputs under certain conditions, for example when a transient of a certain level is recorded.

The digital outputs are configured using the PQ Online program.

B. Digital inputs. The digital inputs all have galvanic isolation with a common terminal for

each group of 8 inputs. The digital inputs are used by the fault recorder application. You have

the option of capturing various types of power quality events, for example switch

connections, relay status, etc. The digital inputs can also be used for monitoring other events,

for example when the door of a particular station is opened or closed, the temperature, status,

etc. The digital inputs are easily configured using the PQ Online program.

C. Connection for the Graphical display unit, which can be supplied as an option.

D. RS-232 connection for direct communication with the Computer. This connection is

primarily used for configuration of the unit at site, and can always be used regardless of the

other communication options.

E. RS-232 connection for communication with External modem.

F. Connection for RS-485 communication, which is available as an option.

G. RJ-45 connection for 10-BaseT Ethernet communication, which is available as an option.

H. Connection for Power Supply. If a suitable DC voltage is available this is preferred choice. If

there is no station/internal battery backup, Unipower recommends that you connect the

instrument to an external UPS type battery source in order to prevent power failure

disturbances. The cable connected to the power supply unit of the UP-2210 unit must be

fitted with a 2A fuse. If an AC supply is used, the phase is connected to the + input and the

neutral conductor is connected to the - input on the UP-2210 measure unit. Always ensure

that the UP-2210 unit is grounded, using the input marked with the ground symbol. The UP-

2210 can be ordered with different DC supplies.
