Dual 1x48, High Density Multiplexer Specifications
96 differential channels, 300V Volts/1 Amp
MULTIPLEXER CONFIGURATION: Two independent 1x 48 2-pole Multiplexers. Banks can be connected together
via relays creating a single 1 x 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: 300V DC or RMS, 1A switched (2A carry), 60W, 125VA.
COMMON MODE VOLTAGE: 300V DC or RMS between any terminal and chassis.
