Specification
Two sets of (+, -) terminals that allow other LC devices to delay an
injection
Boolean operator selects whether one or both inputs delay the
injection
Input voltage range: ±30 Vdc
Logic high = > 3.0 Vdc ±10%, logic low = < 1.9 Vdc ±10%
Minimum pulse width = 10 msec
Two terminals (+, -) for recording the following user-selectable
outputs:
• Programmed flow rate
• Sample loop pressure
• System pressure
• Primary head pressure
• Programmed composition (%A, %B, %C, %D)
• Sample temperature
• Column temperature
• Degasser vacuum
Contact closure indicating:
• Sample set is suspended
• Current function is suspended
Maximum allowable current = 0.5 A
Maximum allowable voltage = 30 Vdc
Contact resistance = 0.2 ohms
Contact closure (across terminals 1 and 2) for 1 second on injection
Maximum allowable current = 0.5A
Maximum allowable voltage = 30 Vdc
Contact resistance = 0.2 ohms
Connected to signal ground and used as reference for
outputs
