Function
MultiSlot is an extension module for up to
four communications cards.
The MultiSlot module may be connected to
a UPS (Uninterruptible Power Supply) in
either of two connection modes:
◗ direct connection to the UPS BUS port;
◗ connection via a U-Talk/Basic acquisition
card.
Using one of the two connection modes, the
MultiSlot module acquires measurements,
status information and alarms from the UPS
and transmits the information to the installed
communications cards.
The communications cards provide the
interface for user access to the information
via a wide range of communications
protocols.
The currently available protocols are:
◗ SNMP 10BaseT;
◗ JBus RS232 or RS485;
◗ U-Talk RS232 (ASCII-type protocol,
property of MGE UPS SYSTEMS);
◗ Basic (status information coded using dry
contacts).
MultiSlot-module characteristics:
◗ input voltage: 230 or 120V AC;
◗ input current: 150 or 300 mA;
◗ fuse protection: 500 mA, 250V AC,
delayed;
◗ maximum operating temperature: 35°C;
◗ dimensions: 1 U x 19" (44.45 x 482.6 mm);
◗ weight: 2.8 kg.
