MULTIPLEXER CONFIGURATION: Two independent 1 × 48 2-pole Multiplexers. Banks can be connected together via relays creating a single 1 × 96 Multiplexer. Banks can be isolated from the backplane by relays. Card can be configured for 2 and 4 wire mode.
CONTACT CONFIGURATION: 2 pole form A.
CONNECTOR TYPE: Two 104 pin female D-shells.
MAXIMUM SIGNAL LEVEL: 300 V DC or RMS, 1A switched (2A carry), 60W, 125VA.
COMMON MODE VOLTAGE: 300 V DC or RMS between any terminal and chassis.
VOLT-HERTZ LIMIT: 8 × 107
CONTACT LIFE: > 105 operations at max signal level.
< 108 operations no load.1
