Waters Model Code EST e-SAT/IN Satellite Interface

The Waters e-SAT/IN (Ethernet-SATellite INterface) module is a single-time base, dual-channel, analog-to-digital (A/D) converter. A data acquisition system (Empower) can collect data from either a single channel or both analog channels. The data start and stop times are identical for both channels. The e-SAT/IN module uses a dedicated local area network (LAN) to communicate to the chromatography data acquisition computer. You can control the e-SAT/IN module using Waters Empower software. e-SAT/IN module, front view 

The e-SAT/IN module provides the following: 

• Software-selectable setting for local power line input frequency (50 or 60 Hz). 

• Fixed data acquisition rates at 50 or 60 Hz from 2 to 480 samples per second (Hz). Refer to the table titled “AC line frequency sampling rates” on page 1-4 for specific sampling rates. 

• Up to 24-bits of A/D conversion, depending on the sampling rate. CHANNEL2 POWER DATA 1 0 Waters e-SAT/IN CHANNEL1 Power switch Analog LEDs inputs I/O connector RELAY TTL1 TTL2 INJ START Features 1-3 

• Internal storage buffer (225 K) with a capacity of 1 minute of data when both channels are operating at a data rate of 100 samples per second. 

• One Ethernet 10 base-T connector for communication.

• Two analog data input channels. 

• One BCD input port. 

• Three programmable event outputs. Two use TTL and one uses relay event output. 

• Self-test and internal calibration at power-on. 

• Power-on self-test status indicator (LED). 

• Data status indicator (LED). 

• Dedicated external voltage autosensing power supply
