3D models for all versions in a variety of popular le formats are
available on request.
Connectors
Signals via front panel connectors:
X connections: 50-pin male high voltage D-type
(one for every 25 pairs of X connections)

For pin outs please refer to the operating manual.
Relay Type
The 60-310 is tted with high quality rhodium contact reed relays
specically designed for high voltage switching. These relays are
leaded types (not surface mount) so eld maintenance is greatly
simplied. Spare reed relays are built onto the circuit board to allow
easy maintenance with minimum downtime (60-310-102 has 1
spare relay, 60-310-202 has 2 spare relays, and 60-310-302 has 3
spare relays).
All reed relays are manufactured by our sister company Pickering

Power Source
Universal AC mains supply, 90-120/200-240V 50-60Hz
Power Inlet: Male IEC connector
Power Rating: 100VA maximum
Fuse Rating: 5A, 250V
LAN Interface
Compliant to LXI Standard 1.4, the 60-310 has a 1000Base-T
Ethernet Interface via a standard RJ-45 connector mounted on the
rear panel with an LCD display showing the unit’s IP address.*
*Note: Legacy units may not have 1000Base-T support or be tted
with an LCD display.
“Hot” Switching
This is when the load is switched with the high
voltage source applied. Hot switching may generate
considerable RFI, both within the switching module and on
interconnecting wiring. Care must be taken to suppress or
shield all cabling.
Note that any precaution which adds extra capacitance to
a cable should be taken with great care, even a very small
capacitance at high voltages can cause very large inrush
current through the module resulting in possible switch
weld and excessive RFI.
The 60-310 modules include extensive built-in RFI
suppression circuits that minimize RFI and surge problems.
“Cold” Switching – The Preferred Option for Reliability & Long Life.
With cold switching, the relay is operated before the high voltage
source is applied. In this case the maximum carry current is much
greater, also there will be much less stress on the reed relays, resulting
in improved reliability and life.
Most high voltage sources include a soft start facility which reduces the
likelihood of generating RFI or temporary over-voltage.
High voltage switching modules are often used for isolation testing
applications (e.g. cable, transformer or semiconductor isolation tests),
in these cases, cold switching is nearly always the preferred option to
reduce the risk of high voltage transients that may cause premature
breakdown.
