Models 5843, 5844, 5843S and 5844S
RS232 or TTL
1.2.10.2
Model 5844HRT or Model 5844SHRT can be ordered to accommodate 24 Vdc - 48 Vdc power.
1.2.11 Peripheral Equipment
1.2.11.1
Regardless of the power connection used, Model 5843HRT requires
250 mA (340 mA for the 5843SHRT) within a range of 9 to 15 VDC.
An inadequate power supply not capable of supplying 250 mA over
the entire operating temperature range may cause the Link/Repeater
to malfunction.
Powering the Model 5844HRT
Model 5844HRT may be powered either through pin 9+ (and pin 5-) of the 9 Pin D-
connector or the power connector located on the side of the unit:
1) When powering Model 5844HRT via pin 9 of its D-connector, the IED must supply
at least 250 mA (340 mA for the 5844SHRT). The voltage should be regulated and
within a range of 9 to 15 Vdc.
2) Model 5844HRT has an internal regulated power supply that may be connected
directly to ac or dc station power. The station power may be 90 to 250 Vac, 50/60
Hz or 90 to 250 Vdc. The station voltage may be unregulated, but the circuit must
be capable of providing a minimum of 35mA (50mA for the 5844SHRT)
continuously. Model 5844HRT has a ground stud (#6-32 bolt) and a power
connector on the side of the case. If Model 5844HRT is powered through the power
connector, then connect a suitable earth ground to the grounding stud on the side
of the Link/Repeater. Remove the power plug from the power connector of the
Link/Repeater. Connect the power lines to the power plug being careful not to
leave any wire strands exposed.
This power input to the Model 5844HRT is Surge Withstand Protected to IEC
61000-4-4, EN61000-4-5 Standard and ANSI/IEEE C37.90.1-1989.
When installing a Model 5844HRT or a 5844SHRT Link/Repeater, an
earth Ground must be attached to the Ground Stud on the side of the
case before connecting to power. Failure to follow this procedure
may result in electrical shock to personnel.
IED
An IED is any intelligent electrical device such as; a computer, RTU, PLC, "smart" meter,
relay, etc., that has the ability to communicate data via RS-232 or TTL format. The IED
should have a communication port for the connection of the Link/Repeater. If the IED's
communication port connector does not accept the Link/Repeater to be plugged in directly,
an adapter must be made to accommodate the connection. Care should be taken to assure
