TORNADO SPECIFICATIONS
RELAY DESCRIPTION
using Tornado-PLC cable
The solid-state relay is mounted on a PCB, which is
Part number 351-063
housed in a 15 pin D-type connector.
Connection to the relay output is via a 5 metre length
screened cable. The end of the cable is left with bare
wires to allow appropriate termination to the peripheral
PLC device.
ELECTRICAL
Supply voltage:
The relay is powered from a 5V regulator inside the Tornado.
Input control:
The relay state is controlled via a TTL signal from the Tornado and
is in a 'closed position' when a logic '1' input is applied.
Output characteristics of Relay (351-063)
Peak relay ac voltage:
350 V
Continuous relay load current (PEAK AC):
120 mA
Maximum relay peak load current:
300 mA
Typical relay contact resistance at 100 mA:
17
(Ohm)
Isolation voltage between Tornado and relay output:
1500 V ac
WATER RESISTANCE
The Tornado is rated to IP54 water resistance.
Note: This IP rating is only valid when no charger or comms cables are connected, and the
charger socket cap and comms connector cover are in place.
ADAPTOR/CHARGER UNIT
The mains adaptor/charger supplied with the Tornado is a constant-current type.
Primary:
230V - 50Hz (110V - 60Hz version also available)
Secondary:
100mA constant current at 9V
Charger output plug:
Centre = positive Outer = negative
